Abstract
The experiment was carried out atZhangye Irrigation Experiment Station in Gansu Province to investigate the effects of water stress in different stages on the change of photosynthetic properties of greenhouse grape under delayed cultivation.The results showed that the net photosynthetic rate under all treatments of water stress was higher than that under the control.However the intercellular CO2 concentration under all treatments of water stress was obviously lower than that under the control,and itwas ranked from high to low according to the successive order ofwater stress.Water stress could improve the appearance quality of delayed grape.The single fruit weight,longitudinal diameter and transverse diameterwere the largest under moderate water stress in flowering stage.Under the treatment of moderate water stress in sprout stage,both the yield and the nutritional quality of grape could be improved,and the wateruse efficiency of leaveswas the highest.These results could provide basis forirrigation system of greenhouse grape underdelayed cultivation so as to save water,improve quality and increase efficiency.
