摘　　要：以鸭梨为试材,研究了外源水杨酸对叶片内源多胺含量变化的影响。结果表明:不同浓度水杨酸处理对多胺含量变化的影响不同,低浓度的水杨酸处理在一定的时间内提高了叶片内源多胺的含量,而高浓度的水杨酸则抑制内源多胺的合成。在田间试验中,5月26日至7月26日腐胺和亚精胺含量显著提高,精胺含量无显著变化。Effects of exogenous salicylic acid on the changes of endogenous polyamines levels in leaves of ＇Yali＇ pear were studied.The results showed that different concentrations of salicylic acid had different effects on polyamine metabolism.Salicylic acid treatments at low concentrations improved the contents of endogenous polyamines in leaves in a certain period of time,while salicylic acid at high concentrations inhibited the synthesis of endogenous polyamines.In field trials,putrescine and spermidine content were significantly increased during 26th May to 26th July,but Spermine levels did not change significantly.
