【摘要】 通过测定未受栗瘿蜂为害和受害2种条件下不同抗栗瘿蜂性锥栗品种叶片的PAL活性,研究锥栗抗栗瘿蜂与PAL活性的关系.结果表明:未受栗瘿蜂为害时,抗、感品种PAL活性无明显差异;栗瘿蜂的为害胁迫可诱导抗栗瘿蜂品种PAL活性提高,感虫品种不产生诱导反应.更多还原

【Abstract】 The relationship between the resistance of Castanea henryi against Dryocosmus kuriphilus and the activity of phenylalanine ammonia-lyase(PAL) was studied by determining the activity of PAL in the leaves of different resistant varieties of C.henryi under different damage conditions.It was indicated that there was no difference in the PAL activity between resistan varieties and susceptible ones when all varieties were not harmed by D.kuriphilus,meanwhile the PAL activity of resistan varieties increased as induced by the harm of D.kuriphilus,but the PAL activity of susceptible varieties did not response to the harm.更多还原
