摘要：用不同浓度的水杨酸（0、2、5、10 mg·L^-1）,浸根处理1 a生油松苗木。结果表明,随着处理后时间的推移,根系活力有先增大后减小的变化趋势,其中5 mg·L^-1的水杨酸提高活力效果最明显,比对照根系活力可提高1-4倍;根长度、根表面积、根数量均是各处理间差异明显,达极显著水平,其中5 mg·L^-1的水杨酸作用最为明显,3项指标分别较对照提高了10.8%-32.9%、23.3%-31.8%和18.3%-39.9%。
Different concentrations（2 mg·L^-1,5 mg·L^-1,and 10 mg·L^-1） of salicylic acid（SA） were used to investigate the effects of SA on the root vigor and morphology of Chinese pine seedlings.The results showed that root vigor increased first,and then decreased.Significant differences were found among the different treatments in indices of root length,root surface area,and root number,in which SA with the concentration of 5 mg·L^-1 exhibited the most significant effect in promoting the root vigor,1-4 times more than that of the control,the indices above mentioned increased by 10.8%～32.9%,23.3%～31.8%,and 18.3%～39.9%,respectively,compared to the control.
