Drought is one of the major abiotic factors affecting growth and productivity of plants by imposing certain morphological, physiological and biochemical changes at different growth stages. The objective of this work is to study key morphological, physiological and biochemical response of faba bean (Vicia faba L. var. 'minor') to soil water deficit stress and to assess the contribution of genetic factors in improving faba bean tolerance to water deficit. Plant of 11 faba bean cultivars were grown in the greenhouse and subjected to three levels of water deficit (90, 50 and 30% of field capacity (FC)) in a simple randomized design for 20 days. Water deficit effects on plant growth, relative water content (RWC), gaz exchange, chlorophyll a (Chla) and Chlorophyll b (Chlb) content, osmoprotectant accumulations (such as proline and soluble sugars), antioxydant enzyme activities and grain yield were determined. Soil water deficit stress reduced growth and affected physiological parameters, especially antioxidant enzyme activities. Water deficit also increased proline, soluble sugars and protein contents. The studied cultivars significantly differed in their responses to water deficit stress. Photosynthetic parameters were less affected in the 'Hara' cultivar. Furthermore, this cultivar produced the highest value of grain yield at 30% FC, and showed higher antioxidant enzyme activities (CAT, GPX and APX), osmoprotectant accumulations, Chlb and RWC. The 'Hara' cultivar was found to be more tolerant to water deficit stress than the other cultivars. Our methodology can be used for assessing the response of faba bean genetic resources to soil water deficit. The identified tolerant cultivar can be utilized as a source for water stress tolerance in faba bean breeding programs aimed at improving drought tolerance. [less ▲]

This study explores important information on biology, genetic resources, taxonomy, as well as morphological, biochemical and molecular markers in order to provide a better understanding of the genetic diversity of the onion (Allium cepa L.). The study has a particular focus on the plant as grown in Africa. The onion is a monocotyledonous, allogamous, and entomophilous plant, with a one-year production cycle for bulb production, and a two-year production cycle for seeds. The onion is one of the most significant vegetables in the world because of its use as both a food and a médicine. [less ▲]

The onion is a very important crop in Niger, which has developed a reputation of high quality for ages. In Niger, many analyses have been carried out concerning onion production, but very little research has been done on onion ecotypes. The aims of this work were to identify the different types of onion produced in Niger. About a dozen sites were visited in the main area of mass production of onion in Niger. Interviews were conducted with ten producers on each site visited. These producers have a good knowledge of the different types of onions produced in the area and all over the country. Descriptors for Allium, established by Biodiversity International (ex IPGRI), have been used to characterize the onion ecotypes. Fifty two locally named ecotypes were identified, but after analysis and grouping by synonyms, it was found that 17 of them were produced in Niger. The main criteria for a local ectoype naming are the colour of the onion bulb and the production area. [less ▲]

Cucumis melo ssp. agrestis is among the most important cucurbit consumed in Côte d'Ivoire. Two varities were identified and used in different areas. One is eaten as soup thickener and the second is used as vegetable. In spite of the socio cultural importance of this species, knowledge of its genetic diversity and differentiation is very poor. little information is available on the variety itself or relationships between the both varieties. Amplified fragment length polymorphism (AFLP) markers were employed to determine the genetic relationships between these varieties in Côte d'Ivoire. Five AFLP primer combinations were used for this study. A total of 75 loci were observed in the 24 accessions with 82.16 % of polymorphic loci ranging between 13.3 % and 100 %. The averages of total gene diversity (HT) and within accessions genetic diversity (HS) were 0.313 and 0.273 repectively. The inter accessions genetic diversity (DST) and the coefficient of gene differentiation among cultivars (FST) were 0.040 and 0.129 respectively. Cluster analysis using Unweighted Pair-Group Method using Néi's genetic distance highlighted two main clusters indicating clearly separation between vegetable and thickener cultivars of Cucumis melo L. ssp. agrestis consumed in Côte d'Ivoire. These data are useful for best management of genetics resources of Cucumis melo L. ssp. agrestis. [less ▲]

Rotylenchulus reniformis is one of the most important nematode pests of cotton. Currently, no cotton cultivar resistant cotton cultivar to this pest is available. In the Framework of a breeding program aiming at producing cotton genotype resistant to this nematode, a R. reniformis resistance evaluation protocol based on egg inoculation, extraction and counting, has been established. Two environment conditions (growth chamber and greenhouse), four sieves (75, 50, 20 and 10 µm), three doses of inoculum (1,500 ; 3,000 and 6,000 eggs), and five durations of infestation (20, 30, 40, 50 and 60 days after inoculation) have been tested. The growth chamber programmed to provide 12h of light, 55% - 60% relative humidity and 30 - 26°C day-night air températures revealed to be adequate. The NaOCI (sodium hypochloride) - blender - sieving - centrifugation - flotation method, using 75-µm and 20-µm sieves, kaolin powder and MgSO4 (magnesium sulfate) solution (specific gravity 1.18) proved to be suitable for effective R. reniformis egg extraction (from roots) and counting. Inoculation of 6,000 eggs per seeding and 60 days duration of infestation seemed to be sufficient dose and period for a reliable resistance evaluation. The protocol developed has been tested on known susceptible and resistant cotton génotypes : G. hirsutum L (main cultivated species through the world, susceptible), G. thurberi Tod. (wild cotton species, moderately susceptible) G. longicalyx Hutch. and Lee (wild cotton species, very resistant). The results obtained were in accordance with the response expected from the génotypes tested, proving the reliability of the evaluation procedure developed. [less ▲]

L'agriculture itinérante sur abattis-brûlis est identifiée parmi les principales menaces aux forêts et à la biodiversité de la localité de Baraka-Fizi en particulier et de la République Démocratique du Congo en général. Cet article propose un modèle agroforestier permettant la fixation des champs et la sédentarisation des élevages et conduisant à des utilisations rationnelles des terres. L'usage des émondes d'engrais verts comme fertilisants ; l'optimisation de leurs doses et modes d'application dans différentes associations de cultures ; les assolements collectifs et l'intégration de l'élevage bovin dans le système de production sont les principales directives de ce modèle. Une gestion optimale et durable de la fertilité des sols et l'amélioration de l'économie paysanne peuvent être attendues grâce aux effets synergiques entre les productions agroforestières (engrais verts), vivrières, fourragères et bovines.

Entire plants were regenerated from nodes explants of Jatropha curcas L. following a procedure of bud aggregate induction on MS (Murashige and Skoog) medium supplemented with 25 mg.l-1 citric acid, 12.2 mg.l-1 adenine sulfate, 15 mg.l-1 L-arginine, 2.46 µM IBA (indole-3-butyric acid), 30 g.l-1 sucrose and 7 g.l-1 of agar, and enriched with different balances of BA (benzyladenine) and L glutamine. The histological studies performed on aggregates showed that the buds result from both the development of axillary buds and adventitious budding starting from underlying tissues of the explant. The culture medium containing 6.65 µM BA and 25 mg.l 1 L-glutamine gave the best results with an average of 64 buds per aggregate after three weeks for all accessions tested. The buds developed into shoots when placed in a MS medium supplemented with 2.21 µM BA, 5.70 µM IAA (indole-3-acetic acid) and 15 mg.l-1 L arginine. These shoots were isolated and then rooted in MS containing 2.46 µM of IBA, 2% sucrose and 0.7% agar. The entire process took 13 weeks with a 98% survival rate in terms of plantlets acclimatization. We obtained a multiplication rate of 13 buds per explant and per subculture which is the double of those obtained in other recent works based on the micropropagation of J. curcas from node explants. This protocol is economically more profitable. [less ▲]

To regenerate adventitious shoots from the cotyledon proximal parts of Citrullus lanatus (Thunb.) Matsum. and Nakai ssp. mucosospermus (Fursa) oleaginous type, different concentrations of MS mineral elements, sucrose, 6-benzylaminopurine (BAP) and agar were tested. Shoot induction proved to depend on the interaction between levels of sucrose, BAP and MS mineral elements in the medium. The medium containing 3/2 strength of MS mineral elements, 35 g/l sucrose and 1 mg/l BAP solidified with 6 g/l agar allowed the production of numerous shoots without a callus phase. After 3 weeks of culture, 76.7% of the cotyledon proximal parts induced shoots with an average of 12.26 shoots per explant and a mean shoot length of 17.13 mm. The induced shoots were directly rooted and thus complete plants ready for acclimatization were obtained using a two steps procedure. Depending on the genotype, the shoot induction from cotyledon proximal parts ranged from 54% to 96%. Rooted plantlets were acclimatized and transferred to field, where they grew well, developed flowers and fruits like seeded plants. The assessment of the genetic stability of the in-vitro-regenerated plantlets by means of an Amplified Fragment Length Polymorphism (AFLP) analysis with the combination of 5 primers revealed no differences between regenerated plantlets and mother plants.
