Abstract

Drought stress adversely impact on the global crop growth and productivity. It is especially important to elucidate the physiological characteristics on plants under drought stress. With the prolongation of drought time, chlorophyll content continued to decline. Root activity increased significantly in mild and moderate drought periods, rapid decline in severe drought period; leaf net photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs) and photochemical efficiency (ФPS?...?) decreased significantly with the increase of drought, while the intercellular CO2 concentration increased significantly. After 7 days of rehydration, there were different degrees of recovery. In mild and moderate drought periods, 'Hong yang' kiwifruit were resistant to drought by reducing the photosynthetic rate.
