摘要:
以“辽园多丽”番茄品种为试材，在高温（35℃/25℃）胁迫下研究了30、60、90、120 mg/L水杨酸（SA）处理对番茄叶片叶绿素、可溶性糖、可溶性蛋白质，脯氨酸及丙二醛含量和对番茄幼苗抗高温胁迫能力的影响。结果表明：番茄幼苗叶片叶绿素、可溶性糖、可溶性蛋白质及脯氨酸含量均随着SA处理浓度的增大而增加，而丙二醛（MDA）含量则表现为先降低后增高。SA对高温胁迫的缓解作用受其浓度的影响，以90 mg/L效果最好。
Abstract:
Using tomoato breed ‘Liaoyuanduoli’ as test material，under high temperature (35℃/25℃) stress，the effect of different concentrations (30,60,90,120 mg/L) of SA on the content of chlorophyll，soluble sugar，soluble protein，proline and malonic dialdehyde (MDA) in tamatoleaves and its effect on increasing the stress resistance of tomato seeding were studied.The results showed that as the increase of SA concentration，the content of MDA increased first and decreased afterwards in tomato seedlings.The relieve from high temperature stress was affected by its concentration of SA and 90 mg/L had the best effect.
