Effet du stress hydrique sur les paramètres morphophysiologiques de la pomme de terre (Solanum tuberosum L.)

Abstract

The potato (Solanum tuberosum L.) is the most demanded vegetable on the market, its production requires intensive cultivation methods. Our work focuses on the reactions of the plant to two doses of water (50% and 100% of the retention capacity of our soil). The effect of water stress on certain morphological and physiological characteristics of the potato crop of the Désirée variety such as the number of leaves, the height of the stem and the length of the roots, as well as the monitoring of physiological parameters (water content total, the relative leaf water content, the chlorophyll rate made it possible to record the influence of the lack of water.The 50% irrigation dose had a negative effect on the morpho-physiological parameters of the potato.
