| 摘 要： | 跳甲是油菜苗期最主要的虫害。以42个油菜品种（系）为供试材料,通过分析田间跳甲为害指数和测定4种主要防御酶苯丙氨酸解氨酶（PAL）、多酚氧化酶（PPO）、过氧化物酶（POD）及超氧化物歧化酶（SOD）活性,研究油菜对跳甲的抗性,从中筛选抗跳甲油菜资源。田间跳甲为害指数统计结果显示,芥菜型油菜品种大辣芥、白芥和甘蓝型油菜品种青杂12号、青杂2号的为害指数2年都较低;青杂12号、大辣芥、白芥的PAL、PPO、POD、SOD活性最强。综上,甘蓝型油菜品种青杂12号、芥菜型油菜品种大辣芥和白芥抗跳甲能力最强,可以作为抗跳甲资源。

| Abstract: | Flea beetle is a serious pest during the seedling stage of the oilseed rape. In this study, 42 rapeseed varieties (lines) were used as materials to explore the resistance to flea beetle and to select resistant resources. We identified the natural hazard index and the activities of four main defensive enzymes including phenylalanine ammonialyase (PAL), polyphenol oxidase (PPO), peroxidase (POD) and superoxide dismutase (SOD). The results of two years field experiments showed that Dalajie and Bajie (B. juncea) and Qingza 12 and Qingza 2 (B. napus) had low hazard index. Defence enzyme activities results also elucidated that the Qingza 12, Dalajie and Baijie had high activities of PAL, PPO, POD and SOD. Comprehensively these two results, it exhibited that Qingza 12, Dalajie and Bajie had the strongest resistance to the flea beetle damage and could be used as resistant resources. |
