Abstract

Abstract: The paper aims to find the suitable irrigation pattern of ‘Yannong 5158’ under the climate condition in Jiaodong area, the authors studied the effects of different irrigation patterns on physiological characteristics, yield and yield components of ‘Yannong 5158’. The results showed that: the relative water content of flag leaf, Fv/Fm of flag leaf and photosynthesis rate of ‘Yannong 5158’ were improved with irrigation time increase; the relative water content of leaf, actual carboxylation efficiency and photosynthesis rate of ‘Yannong 5158’ was higher than that of ‘Lumai 21’, which indicated that the drought resistance of ‘Yannong 5158’ was stronger than that of ‘Lumai 21’; drought stress decreased the yield of ‘Yannong 5158’and ‘Lumai 21’, and the yield of ‘Yannong 5158’ was higher than that of ‘Lumai 21’. Among the three irrigation treatments, the yield in the third treatment was the highest.
