| 摘 要： | 以5年生杏树为试验材料,研究不同浓度三十烷醇(TA)溶液对其光合作用的影响。结果表明:杏树净光合速率(Pn)、气孔导度(Gs)、蒸腾速率(Tr)及胞间CO2浓度(Ci)均表现为"双峰"型,Pn、Gs和Tr日平均值表现为1.0mg·L-1>0.5mg·L-1>0.3mg·L-1>0.1mg·L-1>CK>3.0mg·L-1,Ci日平均值则表现为3.0mg·L-1<1.0mg·L-1<0.5mg·L-1<0.3mg·L-1<0.1mg·L-1

| Abstract: | Apricot trees were used in this experiment to study the effects of different concentrations of triacontanol(TA) on photosynthesis of the trees.The results showed that there were two peaks in the diurnal variations of net photosynthetic rate(Pn),stomatal conductance(Gs),transpiration rate(Tr) and intercellular carbon dioxide concentration(Ci),the sequence of Pn,Gs and Tr was 1.0 mg·L-1> 0.5 mg·L-1 >0.3 mg·L-1 >0.1 mg·L-1 >CK> 3.0 mg·L-1,while the sequence of Ci was 3.0 mg·L-1 <1 mg·L-1< 0.5 mg·L-1 <0.3 mg·L-1 <0.1 mg·L-1
