Abstract

Solenostemon rotundifolius is a tuberous plant with great food and economic potential in Burkina Faso. One of the major problems in its production is the loss of seedlings during storage, resulting in a shortage of raw materials at planting time. The aim of this study was to assess the effectiveness of methods for preserving S. rotundifolius seedlings. A randomized block design with three (03) replicates was used. Twelve (12) preservation methods were tested. Measurements were made on the rate of budded seedlings, budding time, bud length and seedling loss rate. The results showed that six (6) conservation methods produced seedlings with a budding rate of over 80% and low seedling loss rates, ranging from 2.38% to 6.19%. These are: conservation in “Bitatoré” with millet husks as additive (BITA+G) with a seedling budding rate of 89.05 ± 2.27%, canaries with sand as additive (CAN+S) with a budding rate of 87.62 ± 2.17%, “Bitatoré” without additive (BITA) with a budding rate of 86,19 ± 2.33%, Storage in Sand and Sprouting (Tri S) with a budding rate of 85.71 ± 2.72%, canaries with wood shavings as additive (CAN+CB) with a budding rate of 85.24 ± 2.35% and canaries without additive (CAN) with a budding rate of 85.24 ± 2.54%. In addition, the seedlings produced by these methods had respective seed loss rates of 2.86%, 2.86%, 6.19%, 2.38%, 3.81% and 5.71%. The results also showed that seedling budding time varied from 51 ± 4 to 70 ± 3 days, depending on the storage method.

Introduction

Solenostemon rotundifolius (Poir.) J. K. Morton, native to tropical Africa (Tindall, 1983), is an annual herbaceous member of the Labiaceae family (Schippers, 2002). It is cultivated in several African countries, notably in West Africa (Burkina Faso, Ghana, Mali, Nigeria, Togo), in Central Africa (Cameroon, Chad) and in parts of South and East Africa. 

In Burkina Faso, S. rotundifolius is mainly grown for its edible tubers. Indeed, S. rotundifolius tubers are used as a staple food in rural areas and as a dietary supplement in urban areas (Nanema, 2010). S. rotundifolius tubers contain protein, carbohydrates, fiber, lipids and are rich in minerals such as calcium, magnesium, iron, potassium, sodium, phosphorus, manganese, copper, zinc and chromium (Gouado al., 2003; Prematilake, 2005, Enyiukwu et al. 2014, Sethuraman et al., 2020; Kwazo et al.,2021). In addition to these nutritional values, S. rotundifolius is of great medicinal importance. Due to the intermediate glycemic index content of its tubers, S. rotundifolius is recommended as a meal for people with type 2 diabetes mellitus (Eleazu et al., 2017). Tubers reduce blood cholesterol levels (Abraham et al., 2005) and possess strong antioxidant activity (Sandhya et al., 2000, Kwarteng et al., 2018). Also, the leaves and tubers are used in the treatment of several illnesses such as coughs, angina, dysentery, sore eyes (Ouédraogo et al., 2007) and fungal and viral infections in humans (Kwarteng et al.,2018). In addition, the marketing of tubers is a source of income for producers. Thus, a survey conducted in Ouagadougou, Burkina Faso, revealed that the price of one kilogram of S. rotundifolius tubers was 1.2 to 3 USD (Nanéma al., 2017). Grubben (2004) also reported trade in S. rotundifolius tubers between northern Ghana and Burkina Faso. Despite the plant's many potential uses, it remains under-exploited for a variety of reasons. In Burkina Faso, S. rotundifolius is generally grown by elderly people on small areas (Ouédraogo et al., 2007). In addition, one of the major problems is the difficulty of preserving the seedlings that are the agricultural raw material, particularly their loss during storage (Tindall, 1983). Studies have shown that the lack of appropriate methods for the post-harvest conservation of tubers is the cause of huge losses that can reach 20 to 40% of production (Sugri et al.,2013). Indeed, more rotting occurs during seed conservation. Also, pre-harvest and post-harvest operations damage the tuber integuments, making them more susceptible to attack by micro-organisms (Mohammed, 2013).

In rural areas, growers have developed endogenous methods for preserving S. rotundifolius seedlings. These methods involve keeping the tubers in cool, dry conditions, away from light, cooking salt and fats (Bognounou, 1970, Gouado et al., 2003, Ouédraogo et al., 2007). Seedlings are generally mixed with crop residues (millet husks) and stored in containers such as granaries and canaries (Ouédraogo et al., 2007). However, the problem of preservation remains a major constraint, hampering production. The aim of the present study is to identify the best methods for conserving S. rotundifolius seedlings. Specifically, it aims to: (i) assess the effect of conservation methods on seedlings, (ii) identify conservation methods that promote better seedling budding.

Abstract

The present study was conducted from August 2020 to December 2021 to count the vertebrate population and to examine the negative impact cause their scarcity. The Maslakh range forest (30°03′ to 30°21′ N and 66°31′ to 66°49′ E) extends over an area of 115,040 hectors with an altitude of 1406 meter to 4228 meter. Standard methods such as track counts, point surveys, line transects, road side counts, pellet counts, trapping, fresh holes, tracks counting, baited spotlight trick and normal spotlight were used to record the number of mammal species. For aves fauna survey strip census trick was used, and for reptiles, amphibian species direct counting (night observations, one-hour plot searching, stones, rocks and rotten trees turning) were processed, while indirect counting (informations) were obtained from field staff, game inspectors, game watchers, and local villagers. In total 153 vertebrate species including 28 mammals (18.30%), 100 birds (65.36%), 22 reptiles (13.92%) and 3 amphibians (2.06%) were recorded. Threatened species recorded were Striped hyaena (Hyaena hyaena Linnaeus, 1758), Indian wolf (Canis lupus Linnaeus, 1758), Balochistan urial (Ovis vignei blanfordi Blanford, 1894), Chinkara (Gazella bennettii Sykes, 1831), and the imperial eagles (Aquila heliaca Blanford,1894) found to be critically endangered. It was observed that hunting and capturing of animals of the study area and native live-stock grazing were known to be the main reasons of fauna and flora decline. Another important factor was noted to be droughts intensity due to climatic change of the area. It is concluded that prompt management plan of the Forestry Department Balochistan (Balochistan wildlife Protection, Preservation, Conservation and Management) Act 1974 may be implemented in its full spirit at the earliest to save the vertebrate fauna, vegetation and natural fresh water reservoirs of Maslakh range forest, Pakistan.

Introduction

In Balochistan province (Pakistan), the marked decline in biodiversity happened due to anthropogenic activities like deforestation, species migration, and habitat fragmentation (Groombridge, 1998; Qasim et al., 2017). Other factors that violate biodiversity include increased human and live-stock population, habitat destruction, global warming, and also putting the lives in danger of some useful and unique species (Rawat & Agarwal, 2015; Tareen, 2017; Baboo et al., 2017; Javed, 2019). 

Major threats to vertebrate fauna diversity and habitat loss are forest degradation, wood logging, hunting, and disturbance by humans of the area (Khan et al., 2018). Maslakh wildlife protected area was established in 1968. The area was declared as a wildlife sanctuary for chinkara and urial (IUCN, 1997; Groombridge, 1998; WWF-Pakistan, 1998; Government of Balochistan and IUCN Pakistan, 2000; Ghalib et al., 2007) according to Balochistan wildlife (Protection, Preservation, Conservation, and Management) Act 1974. 

The Chinkara population in Maslakh range forest was almost wiped out by large hunting (Virk, 1991). The hill ranges are drained by main rainy Pishin river (Said & Hussain, 1959). The middle belt of about 8-9 km has no surface or groundwater (Said & Hussain, 1959).

Maslakh range (state) forest lies in the Olive-Pistacia vegetation zone. Due to extreme lopping and overgrazing in the past, tree growth in Maslakh is represented only by Pistacia khinjuk and infrequent copies of Fraxinus xanthoxyloides (Rafi, 1965). The predominant tree species are Olea ferruginea, Pistacia khinjuk, Prunus eburnea, Stocksia braubica and Berberis vulgaris. Artemisia maritima and Cousinia minuta constitute the main ground cover above 5,500' while Hammada griffithii replaces Artemisia in lower parts. The major grassses are Sipa pennata, Chrysopogon aucheri, Cymbopogon schoenanthus, Aeluropus littoralis, Poa sinaica and P. bulbosa (Rafi, 1965; Marwat et al., 1989). 

As previously, no literatures are available on vertebrate fauna diversity of Maslakh range forest Quetta. Therefore, to accomplish this gape of scientific knowledge, the vertebrate population count was estimated and the bio-ecological problems of the study area were determined. The management strategy required for conservation and organization of wildlife in the range forest was proposed.

Mycotoxin-Producing Fungi in Eritrean Sorghum: Market-Sourced Incidence Study | InformativeBD

Geofrey Sing’ombe Ombiro, from the institute of Eritrea.  and Nadin Issak, from the institute of Eritrea. wrote a Research Article about, Mycotoxin-Producing Fungi in Eritrean Sorghum: Market-Sourced Incidence Study. Entitled, Incidence of mycotoxin producing fungi in sorghum sourced from different markets of Eritrea. This research paper published by the International Journal of Agronomy and Agricultural Research (IJAAR). an open access scholarly research journal on Agronomy. under the affiliation of the International Network For Natural Sciences | INNSpub. an open access multidisciplinary research journal publisher.

Abstract

Sorghum serves as staple food for over 100 million people in Sub-Saharan African countries. It is the most important nutritional security crop. However, sorghum is susceptible to contamination by molds that produces aflatoxin that causes hepatoxin and carcinogenic effects on humans and animals. This study was conducted to survey sorghum storage conditions in relation to mycotoxin contamination and to determine the efficacy of neem against Aspergillus flavus. The survey was done through questionnaires in Asmara, Keren and Asmat. The survey determined that sorghum is stored together with other cereals in all the markets. It also determined that sorghum sold in Asmara, Keren and Asmat is obtained from different places such as; Anseba, Mendefara, Gashbaka and Halhale. The survey also determined that most of the sorghum in the markets has been in storage for between 3-12 months with very little being stored longer than 1 year. In terms of control, sorghum sellers use a combination of fungicide and local remedies to eliminate pests and diseases. The common fungicide reported to be used was Tanphos with the local remedies used being; chillies, neem, lime and ash. We identified mycotoxins such as Fusarium and Aspergillus spp. in sorghum seed obtained from different markets of Eritrea. Treatment with neem was found effective as it diminished the radial growth of Aspergillus flavus. The concentration of mycotoxins specifically Aspergillus flavus in all sorghum samples was found to be higher. Therefore, attention should be given by responsible authorities to mitigate the effects of the mycotoxins.

Introduction

Sorghum (Sorghum bicolor L. Moench) is the world’s fifth most important cereal crop that is shaped like a little ball coated with an edible hull. Sorghum is used as a major food and nutritional security crop for more than 100 million people in the Horn of Africa (Katile et al., 2010). Ethiopia is one of the major centers of origin and diversity for Sorghum cultivation (Mekbib, 2009). The lives of Eritreans depend on Sorghum as a staple food crop. It's versatile: sorghum can be broken down into flour for baking, boiled to make a side dish, and popped like popcorn. The sorghum plant has a natural drought tolerance, which means it can grow just about anywhere it's cultivated. Sorghum is susceptible to many abiotic and biotic factors and among the biotic factors are diseases caused by fungal pathogens such as moulds. The greatest concern for mould growth in food crops is the production of mycotoxins that are harmful to human and animal health (Prom et al., 2021; Wu, 2015). The mycotoxin producing fungi include; Aspergillus sp., Penicillium sp. and Fusarium sp. (Wogan, 2012). 

Aflatoxins are naturally occurring toxic secondary metabolites of storage fungi (Aspergillus flavus) produced in agricultural production stored inappropriately and at high moisture and temperature. (Chulze et al., 2010). The fungus is common in areas with stressful conditions like drought. Aspergillus sp. contains a diverse group of microorganisms producing different types of mycotoxins (Fung et al., 2004). There has been a report of fungal contamination of cereal crops such as sorghum with aflatoxins worldwide. Bio-fungicides or biological pesticides are formulations made from naturally occurring substances that control pests by non-toxic mechanisms and in an ecologically friendly manner. Bio-fungicides have been defined as a form of pesticides based on microorganisms or natural products (Meena, 2021). Anonymous (2014), reported that plant extracts were likely the earliest agricultural bio fungicides. Farmers surveys carried out in Ghana have highlighted that many farmers do not use commercial synthetics (Belmain and Stevenson, 2001) and instead, use plant-based products. Many farmers in Asia and Africa have been using plant extracts such as neem (Azadirachta indica), wild tobacco (Calotropisprocera), wood ash and dried chillies among others for controlling and repelling some insect pests (Anukwuorji, et al., 2012; 2013; Ahmed et al., 2005).

Surveys of the disease in various African countries have shown high disease incidences sometimes resulting to deaths (Astoreca et al., 2019). Mycotoxins such as aflatoxins in human and animal diets can lead to aflatoxicosis. There has been no report on incidences of mycotoxins in major cereals consumed in Eritrea such as sorghum. Therefore, it’s important to screen sorghum grains for mycotoxins contamination. One of the most important mycotoxins is Aspergillus flavus, the causal agent of aflatoxins. Efforts to control aflatoxins have utilized different methods. However, most of the efforts have utilized synthetic chemicals that are not environmentally safe and can be toxic to human and animals. There is need for development of safe alternatives to control aflatoxins. Many botanicals have been shown to inhibit different fungal pathogens. These botanicals have been shown to be environmentally safe and non-toxic to human and animals. This makes them potential bio-fungicides in the management of aflatoxins in Eritrea.

Abstract

The need to produce a cheap alternative and farmer level technology in the production of clean planting materials of White Potato (Solanum tuberosum L.) prompted the investigation on the rooting response of clones from stem cuttings of different age and number of nodes under different concentrations of synthetic plant hormone Alpha-Naphthalene Acetic Acid (ANAA). A zero generation (G0) mother plant was used as a source of clones to examine whether it could produce roots in a sterilized medium. In a replicated split-split plot experimental design with three factors such as the age of the mother plant, number of nodes and levels of growth regulator, we found that roots emerged from clones 18 days after planting in a sterilized river sand. Significant effect on rooting was influenced by the age of cuttings (p=0.0058), number of nodes (p=0.0058) and ANAA (p=<0.0001). Moreover, significant interactions were found among age of cuttings, number of nodes and ANAA concentrations on rooting (p=0.0044). Implications for the feasibility of mass producing clean planting materials from cloning G0 mother plant are discussed.

Introduction

White potato (Solanum tuberosum L.) is a perennial crop belonging to the Solanaceae family grown mainly for its tubers (Spooner et al., 2014). First cultivated 8000 years ago by the Peruvian farmers in Peru’s Central Andes; now it has more than 4000 different cultivars grown globally (Niekerk et al., 2016; Lutaladio et al., 2009). It was initially introduced in Europe in the sixteenth century and was subsequently distributed throughout the world. Potatoes are the world’s primary non-grain staple food in several countries in Europe and some parts of America due to its nutrient content; with China, India, Ukraine and Russia as top producers (Lutaladio et al., 2009; Shahbandeh, 2022).

The biggest obstacle of the white potato industry in Asia, particularly Philippines is the source of clean planting materials, because potatoes are attacked by bacterial wilt disease caused by pathogen Ralstonia solanacearum. The conventional method of white potato propagation is through the use of tubers, but the risk is high. Other methods are the use of True Potato Seeds (TPS), and through stem cuttings (Morais et al., 2018; Shiwani et al., 2021). At present, the Department of Agriculture’s Northern Mindanao Agri Crops and Livestock Research Complex (DANMACLRC) uses the tissue culture technology to mass produce seedlings and tubers as the source of potato clean planting materials, but cannot cope up with the current demand; thus there is pressure to explore other methods.

Numerous studies were conducted to explore and enhance the propagation of potato through stem cuttings. The work of Zaki and Moustafa (2018) for example, used Indole Acetic Acid (IAA) and Indole Butyric Acid (IBA) at higher concentrations reaching up to 6000 parts per million (ppm) but rooting responses of potato varieties tested differ significantly. Ezzat (2016) dipped the stem cuttings for 1 minute to various rooting hormones such as Indole-3-butyric acid Potassium salt (K-IBA) at 1000 ppm, IAA at 250, and 1-Naphthaleneacetic acid NAA at 500 mg/L. The same hormone IAA was tested by Nikmatullah et al. (2018), but other factors such as age of mother plant and number of nodes was included.

In this study we explored the responses and interactions at different ages of Granola white potato stem cuttings, number of nodes, and levels of hormones in terms of its rooting ability and growth. Results and its potential for tuber production are discussed.

Abstract

Electronic drug delivery systems (EDDS) are an interesting advancement in drug delivery technology. They are portable, interactive, wirelessly networked, and enable patient-administered medication, which lowers overall healthcare costs. Controlled DDS maintains drug plasma levels constantly by releasing the definite dose of the drug at each time point for a predetermined duration. This helps in reducing the dose and dosing frequency and improves patient compliance. Lesser drug exposure to the biological environment reduces drug toxicity and adverse effects. Among controlled release. Transdermal delivery mode (referred to as patches) is more preferably used among them because of great patient compliance. Bioelectronic systems play a crucial role in electronically controlled drug delivery systems by integrating electronic components with biological systems to deliver drugs with precision and efficiency. Their efficiency is further increased when integrated into remotely operated systems. One of the main motivations for developing EDDS was to increase patient adherence to recommended drug regimens. Moreover, EDDS have demonstrated the ability to administer drugs to specific body locations on demand. This review concentrates on electronic medication delivery systems, despite the fact that there are many different types of drug delivery devices on the market. Along with their mechanism of actions are also discussed.

Introduction

Controlled drug delivery system This is the drug delivery system in which a constant level of a drug is maintained in blood and tissue for an extended period. Controlled DDS maintains drug plasma levels constantly by releasing the definite dose of the drug at each time point for a predetermined duration (Tekade et al., 2018). This helps in reducing the dose and dosing frequency and improves patient compliance. Lesser drug exposure to the biological environment reduces drug toxicity and adverse effects.

Evolution of the controlled release dosage forms First-generation: This generation of dosage forms mainly involves four types of mechanisms for drug release, which include the oral and transdermal formulations. The mechanisms involved are dissolution, osmosis, diffusion, and ion exchange. Diffusion and dissolution-controlled systems are the most widely used mechanisms of drug delivery. The success of the first generation of drugs is mainly the development of the oral and transdermal routes (Park et al., 2014).

Second-generation: These are not widely used. Electrically delivery systems were developed for introducing insulin. Due to its lesser bioavailability, it is administered many times higher per dose than is required, which results in toxicity. In the last decade of the second generation, nanoparticles that target genes and tumors were studied. 

The third generation: involves the delivery of poorly water-soluble drugs, long-term and non-invasive technology for delivering proteins/nucleic acids/peptides, and drug delivery to the targeted site using nanoparticles (Yun et al., 2015).

Formulations of controlled-release medication Oral, intravenous, and transdermal patches are easily developed. Among controlled release, transdermal delivery mode (referred to as patches) is more preferably used among them because of great patient compliance.

Abstract

Despite the good nutritional qualities and large production areas of plantain bananas, their production is subject to a lack of inexpensive conservation techniques that are accessible to everyone. For this, a conservation study combining charcoal and polyethylene bags was carried out. For this work, the fruits of the plantain varieties Saci, Big-Ebanga and Orishélé harvested at the mature stage were preserved in six different storage media. Some physicochemical and antinutritional parameters such as polyphenols, flavonoids and phytates of the pulps of the three varieties of plantain bananas were determined according to standard methods. The results obtained indicate that the storage time in the media containing charcoal exceeded 30 days, unlike the control media where the storage times were 12 and 24 days. of polyphenols between 120.66 and 1961.10mg/100g DM and finally of flavonoids between 0.76 and 7.23mg/100g DM. Regarding the antinutritional parameters, the phytate levels vary between 42.66 and 64.05mg / 100g DM.

Introduction

The plantain banana is a fruit which, in addition to contributing to food security, is an excellent source of carbohydrates for its high content of complex carbohydrates (starch), thus providing consumers with the bulk of total energy with rates varying from 89 to 90.52 Kcal per 100g of dry matter (FAO, 2003). Apart from carbohydrate parameters, plantain also contains phytochemicals. Indeed, they are natural and biologically active chemical compounds in plants. They act as a natural defense system for host plants and provide color, aroma and flavor. They are localized on fruits, seeds, stem epidermis, flower and other peripheral surfaces of plants. They are a group of bioactive substances inherent in plants and are responsible for protecting these plants against environmental stress, microbial attacks, insects and other external aggressions (Daramola and Adegoke, 2011). The consumption of foods rich in phytochemical compounds such as carotenoids, polyphenols, isoprenoids, phytosterols, saponins, dietary fibers, polysaccharides, etc., allows, on a curative or preventive basis, to spare consumers from diseases such as diabetes, obesity, cancer, cardiovascular diseases, etc. (Ashwani et al., 2023). In addition, the plantain (Musa spp), like most tropical fruits and vegetables, is highly perishable. Given its perishable nature, a practical, accessible and inexpensive method of preservation, unlike known methods, has been tested with the aim of contributing sustainably to food security by reducing post-harvest losses. The interest of this work is then to evaluate the impact of this charcoal-based preservation method on some phytochemical parameters of these plantain fruits during storage
