摘要:

为研究植物营养与其抗性的关系,对兴安落叶松和长白落叶松在不同结实情况下针叶内PAL、PPO、TI和CI活性的变化规律进行分析。结果表明:2种落叶松都表现为在结实量较少或无时,其防御酶及蛋白酶抑制剂的活性较高,且与结实量中等或结实量较多时的防御酶及蛋白酶抑制剂的活性存在显著差异(P<0.05)。兴安落叶松与长白落叶松之间防御酶和蛋白酶抑制剂的活性无显著差异(P>0.05)。落叶松抗虫性的强弱与其结实量有直接的关系,但与种类关系不大。

Abstract:

In order to investigate the relationship between plant resistance and plant nutrition,this study measured the change pattern of PAL,PPO,TI and CI activity in needles of Larix gmelinii and L.olgensis with different coning grades.The results showed that when the coning less or no,the two larches had higher activities of defense enzymes and more protease inhibitors, and the enzyme activities and the inhibitors were significantly different from that when the coning performance was in middle or above grade(P<0.05).There were no significant differences in the activity of defense enzyme and protease inhibitor between L.gmelinii and L.olgensis(P>0.05).The results indicated that coning number of larches had the direct impact on the resistance to the pest insects.

Key words: Larix gmelinii, Larix olgensis, coning quantity, plant resistance, defense enzymes, protease inhibitor
