Résumé
Spiderplant (Gynandropsis gynandra (L.) Briq.) and African nightshade (Solanum spp.) are important leafy vegetable crops consumed by various rural communities in Kenya. They are important sources of nutrients and have medicinal value. Unreliable rainfall, intermittent droughts and the need for production during dry season necessitate irrigation for successful commercialization of these crops. However. there is only scanty information on the water management of these crops. Moreover, understanding the adaptation of these crops to drought is crucial in devising water management strategies that will maximize production at minimal irrigation costs. The main objective of this work therefore was to evaluate the mechanisms of adaptation to drought in both spiderplant and African nightshade and to relate them to productivity of these crops. Plant growth, relative water content, osmotic potential, water potential and transpiration of three spiderplant genotypes, P-Iandrace and P-commercial (fast growing) and G-Iandrace (slow growing) were investigated under droughted and watered conditions in a glasshouse study
