| 摘 要： | 为明确抗虫绿豆抗绿豆象的有效成分, 采用室内人工接虫方法, 进行了13个不同绿豆品种(品系)对绿豆象的抗虫性鉴定, 并对筛选获得的抗豆象品种的抗虫成分进行了研究。结果表明, 绿豆象对B18、B20、B23、B27、A22和晋绿7号绿豆的为害率均低于10%, 为高抗型绿豆; 其余7个绿豆品种受害率均在90%以上, 属高感型绿豆。绿豆象卵的孵化率在抗、感绿豆品种间无显著性差异, 而绿豆象发育历期、雌、雄成虫体重及成虫羽化率在抗、感绿豆品种间差异显著, 同一品种去皮绿豆与带皮绿豆相比, 绿豆象卵孵化率、成虫羽化率及种子受害率等指标均无显著性差异。抗虫成分试验表明, 当绿豆象取食添加抗虫绿豆蛋白25%和50%的人工(合成)绿豆后, 其成虫羽化率由30.48%降低到0, 但不随淀粉比例的增加而变化。可见, 抗虫绿豆抗绿豆象的主要成分为其种子中的蛋白质。

| Abstract: | To clarify the effective component in mungbean seeds against bruchid (Callosobruchus chinensis L.), we identified the bruchid resistance of 13 mungbean varieties via in-house artificial feeding method, and the insect-resistant components in mungbean were investigated. Six mungbean varieties including B18, B20, B23, B27, A22, and Jinlyu 7, were found to be highly resistant to bruchid, showing seed-damage rates lower than 10%, whereas, the remaining seven varieties were highly susceptible with seed-damage rates higher than 90%. There was no significant difference in egg-hatch rate among all varieties. However, the developmental duration, the adult-emergence rate ,and the bodyweights of both male and female adults varied significantly between the resistant and susceptible varieties. Moreover, seed coat had no effect on the resistance to bruchid because samples with or without seed coat showed no significant difference in the rates of egg-hatch, adult emergence, and seed damage. The resistance test with synthetic mungbean indicated that the adult-emergence rate declined from 30.48% to 0 when the protein component of resistant mungbean varieties increased from 25% to 50%. In contrast, the increase of starch proportion had no effect on theadult emergence rate. Therefore, we conclude that seed proteins play an important role in bruchid resistance in mungbean. |
