A Comparative Study of Morpho-Physiological Responses of Wild and Cultivated Solanum Species to Water Stress: the Case of S. Sisymbriifolium and S. Macrocarpon

Crop wild relatives are closely related taxa of cultivated crops and are well adapted to a wide range of environmental conditions. With the current global warming and challenges in agriculture and food production, increasing attention must be given to these crop wild species as they can provide genetic resources that may be helpful to address some of the current challenges in agriculture (e.g., adaptation to drought). In this study, we compared the morpho-physiological performances of Solanum macrocarpon and its wild relative Solanum sisymbriifolium under different watering conditions in Benin. Seedlings were grown in plastic pots under shade-house and subjected to low, moderate, and high-water supply (i.e., 25
