Analysis of Relationships Between the Photosynthetic Characteristics of Apricot and the Harm of Bark Beetle
摘要
Abstract
[Objective and Method] In order to reveal the relationships between the photosynthetic characteristics of apricot and the harm of bark beetle . Saimaiti apricot varieties weR used as the trial materials . The characteristics of photosynthesis in leaves of healthy tree, vulnerable tree and initial stage harm of bark beetle tree were determined . [ Result]The results showed that the net photosynthetic rate ( Pn) , the stomatal conductance( Gs) and the transpiration rate ( Tr) of healthy tree were significantly higher than that of vulnerable tree and harmed tree; The net photosynthetic rate of healthy tree could reach 18 .178 μmol CO2/( m2.s) , but those of vulnerable tree and harmed tree were only 1 . 441 μmol CO2/( m2 . s) and 0. 806 μmol CO2/( m2 . s) respectively; The leaf area of vulnerable tree and harmed tree were smaller than that of healthy tree, and the chlorophyll content of these two were lower than that of healthy tree, too. [ Conclusion]The photosynthetic capacity of the vulnerable tree and harmed tree were far lower than that of healthy tree. Their photosynthesis were significantly inhibited and the change of all the physiological indexes of apricot had a certain effect on photosynthesis.The harm from the bark beetle could be controlled by low photosynthetcc rate .关键词
