Jatropha (Jatropha curcas L.) is a potential biodiesel plant that gained much attention in non-oil production countries. We investigated the ability of the species to cope with water deficit occurring in semi-arid zones like Senegal climatic conditions. The layout of the experiment was a randomized complete blocks design with two factors (level and frequency of irrigation) and 6 repetitions. The trial was conducted from December 2012 to June 2013 in CERAAS/ISRA at Thiès, Senegal. Potted Jatropha seedlings were exposed, after three months under similar well-watered conditions, to three water regimes (100%, 50% and 25% of field capacity, respectively C100, C50 and C25) and two frequency of watering once and twice watering a week(F1 and F2, respectively). The different treatments didn’t affect significantly collar diameter and plant height during the time of the experimentation. Nevertheless, the trend line is up for collar diameter and plant height in well-watered plants. For the same frequency of irrigation, biomass accumulated was high in C100. No difference was found between plants biomass in C25-F1 and C25-F2. For physiological parameters, there are no differences between the treatments at the onset of stress. However, after 2 weeks of stress, photosynthesis, stomatal conductance and transpiration were affected permanently in treatments C100-F1, C50-F1 and C25-F1 and their values never reached those of plants of C100-F2, 50-F2 and C25-F2. The opposite was noted for leaf temperature. For the same frequency of irrigation, photosynthesis, stomatal conductance and transpiration were higher in C100 and the opposite occurred for the leaf temperature. These results demonstrate that growth and productivity of Jatropha are significantly affected by water stress conditions. Its need to be watered regularly to maintain physiological functions and biomass production definitely highlights that its growth in semi-arid zones is economically unlikely.

The major foliar diseases and pathogenicity of fungal flora associated with leaf diseases of Jatropha curcas L were investigated in Burkina Faso. Prospecting and collection were carried out the plantations and hedges of J. curcas distributed in different climatic zones of Burkina Faso. The results indicate that foliar diseases are present in all climatic zones of the country. Mainly 4 foliar pathologies were recorded in the 18 sites of the study. These are yellowing of leaves with brown spots, yellowing of leaves with brown spots and black mycelium, drying of leaves from the border and virus diseases. The frequencies of observation of the various diseases show that the yellowing of the leaves with brown spots is the most disease predominant manifestation with a frequency of observation of 72%. Yellowing of the leaves with a presence of black spots and mycelium occupies the second rank with a prevalence of 33% followed by drying of leaves from borders and viroses with frequencies of 22 and 11% respectively. ANOVA analysis has shown that the climatic zone has a significant effect on the distribution of leaf viruses and leaf burns and a non-significant effect on yellowing of the leaves with or without brown spots and mycelium. The characterisation of fungal pathogens associated with these diseases identified Fusarium oxysporum, Fusarium solani, Fusarium subglutinans, Phoma sorghina, Botrytis cinerea, Curvularia lunata, Botryodiplodiat hreobromae, Cercospora cesami and Curvularia eragrostidis. Curvularia lunata is the most widespread with a frequency of 44% followed by Fusarium solani with a frequency of 33%. The most seldom observed are Cercospora cesamiand Fusarium subglutinans with a frequency of 10%. Among these characterised species, pathogenicity tests identified Botryodiplodia threobromae, Curvularia lunata, Fusarium solani and Curvularia eragrostidisas the pathogenic species of observed leaf diseases of J. curcas. These results confirm that Jatropha is infested by many fungal species. There is yet an urgency to develop a plant health program adapted to the local context to fight these fungal pathogens.
