| 摘 要： | 以朋娜脐橙为材料,采用叶面喷施方式,比较了5种机油乳剂对叶片光合特性影响的差异。结果表明,所有机油乳剂都会在一定时段内显著降低朋娜脐橙叶的Pn、Gs和Tr,提高了Ci,但法夏乐从第4天起多数光合指标高于对照,绿颖处理叶在第7天恢复正常,蚧敌在处理后第25天也可恢复正常,而蚧螨灵和太极机油到处理后第65天各项光合指标仍显著低于对照。所有机油乳剂导致脐橙叶Pn下降既有非气孔因素也有气孔因素,但主导因素为非气孔因素,即机油乳剂降低了叶肉细胞的光合活性。

| Abstract: | In order to investigate the effects of petroleum spray oil(PSO) on photosynthetic characters of citrus,five PSOs were sprayed on the leaves of 30-year-old Skaggas Bonnaza navel orange(Citrus sinensis Osbeck) trees.The results showed that,in a certain period of time after spraying,all PSOs decreased leaf net photosynthetic rate,stomatal conductance and transpiration rate,but increased intercellular CO2 concentration rate.However,most photosynthetic characters of Citrole treated leaves were higher than those ... |
