| 摘 要： | 以红掌(Anthurium andraeanum)叶片为试材,在4℃条件下,测试分析了不同质量浓度(0、1、10、100、1000mg·mL-1)水杨酸(SA)水溶液对红掌叶片活性氧、可溶性糖、可溶性蛋白、丙二醛(MDA)、脯氨酸和细胞膜透性的影响。结果表明:施加SA明显增强了红掌叶片4℃下的抗低温能力。红掌叶片保护酶过氧化物酶(POD)活性先升高后降低;可溶性糖、可溶性蛋白质量分数先上升后下降;MDA质量摩尔浓度和膜透性上升趋势减缓,脯氨酸质量分数下降趋势减缓;O2-释放速率和H2O2质量摩尔浓度总体上先上升再下降,在一定范围内二者出现了一致的变化趋势。与对照相比,冷处理12h时质量浓度为1000mg·mL-1SA处理植株的O2-释放速率、H2O2质量摩尔浓度、POD活性、MDA质量摩尔浓度和电导率分别较对照降低了39.5%、11%、46.7%、35.1%和20.1%。说明质量浓度为1000mg·mL-1的SA水溶液能够有效提高红掌叶片在4℃条件下的抗低温能力。

| Abstract: | An experiment was conducted to study the effect of different concentrations of salicylic acid on activated oxygen,soluble sugar,soluble protein,MDA,proline,and membrane permeability of the leaves of Anthurium andraeanum at low temperature(4 degrees C).Results show that appropriate concentration of salicylic acid could significantly enhance the cold resistance of A.andraeanum leaves at low temperature.POD activity and contents of soluble sugar and soluble protein increased first and then decreased,MDA concen... |
