Abstract:
Taking 15 fresh jujube varieties as the test materials，single factor analysis of variance and correlation analysis were used to study the differences in photosynthetic characteristics，chlorophyll content，and yield among different fresh jujube varieties，in order to provide reference for the selection and introduction of fresh jujube varieties in Xinjiang.The results showed that there were significant differences in net photosynthetic rate，transpiration rate，stomatal conductance and intercellular CO2 concentration among 15 fresh jujube varieties (P<0.01).The correlation analysis showed that the net photosynthetic rate of 15 fresh jujube varieties was correlated with stomatal conductance and transpiration rate.Water use efficiency was negatively correlated with stomatal conductance，intercellular CO2 concentration and transpiration rate.The yield of 15 fresh jujube was positively correlated with the net photosynthetic rate.It could be seen that the photosynthetic characteristics and yield of ‘Fengmiguan’‘Dongzao’‘Xiangcui’‘Saimisu No.1’ and ‘Fucuimi honey’ were higher than other varieties，which were suitable for promotion and planting in Kashgar area of southern Xinjiang.
