Effects of Drought Stress on Leaf Gas Exchange Parameters in Development of Sweet Cherry Fruit

摘要

Aim at the drought, one of the important stress factors, we chose the Prunus avium named 'Hong Deng' to experiment. Through artificial control field soil water content, to different drought stress treatment of sweet cherry, the leaf photosynthetic indicators, including net photosynthesis rate, transpiration rate, stomatal conductance, intercellular CO_2 concentration and. instantaneous water use efficiency were measured in the first fruit enlargement period, the stone hardening period, and the second fruit enlargement period of sweet cherry, which provided some knowledge of the P. avium under drought stress.
