Etude des caractères morpho-physiologique du poivron (Capsicum annuum L.) en milieu de stress hydrique

Abstract

Water availability is one of the most important factors contributing to the good and full growth of all plants. As a consequence of these conditions the agricultural domain suffers due to lack of water. We mater a study of the effect of water stress on the morpho-physiological behavior of the Magister hybrid 1 variety green pepper culture. In this experiment we treated the pepper with two doses of 100% water (1 liter) & 50% (0.5 liter) of the water retention capacity of the water retention capacity of the soil. The results showed that the 50% dose affected the morphological parameters studied (stem length; roots and height of the plant) that caused a deficiency in them. Also the same for the physiological parameters we obtain a decrease in the total water content with an average of 78.27% of the dose 50% and 83.91% of the dose 100%, the relative leaf water content an average of 67.05% of the dose 50% with 67.07% of the control dose but we found a difference in the rate of chlorophyll in the leaves of which the average of the 50% dose was a little 2.17% compared to the control of 2.31%.
