Title: Daily Photosynthetic Variation Characteristics of Different Variteties of Apricots
Abstract: 【Objective】The photosynthetic physioecological diurnal characteristics of different varieties of Xinjiang apricot were surveyed in this paper.【Method】The photosynthesis changes and physiological characteristics between meteorological factors under natural conditions of 10 breeds of Xinjiang apricot were studied by using LI-6400 portable photosynthetic determination system.【Result】The photosynthetic rates in different breeds are significantly great;the highest lies in Kumaiti,which is significantly different from Beishanyulvke,and has an extremely significant difference from other 8 varieties.The photosynthetic rate of daily variation was double-peak curve in selected apricot varieties;the photosynthetic nap phenomenon was presented in these varieties.Temperature,photosynthetic available radiation,and transpiration rate and stomatal conductance were positively correlated with photosynthetic rate and air relative humidity,and intercellular CO2 concentration was negatively correlated with photosynthetic rate in different varieties.【Conclusion】Daily photosynthetic characteristic of different varieties of apricots has the same trend,but the differences exists in parameters.
