摘 要: | [目的]研究大蒜浸提液对菜豆种=产萌发的化感作用强度。[方法]以乙醇为提取剂对大蒜进行提取,用大蒜浸提液处理4个菜豆品种(安蔬高产架豆王、赤裕五号、赤裕三号、抗病泰国新架豆王),测定不同处理的发芽势、发芽率、发芽指数、活力指数、幼苗长度、电导率和POD活性。[结果]大蒜浸提液对4个品种发芽率的抑制率都在20%以下,种子活力指数的抑制率均达80%以上,对幼苗长度的抑制率均达70%以上,对抗病泰国新架豆王发芽势和发芽指数的抑制率最大,分剐为71%和65%。经大蒜浸提液处理后,幼苗电导率和POD活性显著提高。安蔬高产架豆王和赤裕五号的POD活性分别提高了69%、68%。[结论]大蒜化感物质对菜豆种子萌发有较强地抑制作用。

Abstract: | [Objective] The research was to study the allelochemicals intensity of the garlic extract on the seed germination of kidney bean.[Method] The garlic was extracted with ethanol as extractant and 4 varieties(Anshu Jiandouwang with high yield,Chiyu 5,Chiyu 3,Thailand Jiadouwang with disease resistance) was treated by the garlic extract to measure the germination vigor,germination rate,germination index,vigor index,seedling length,conductivity and POD activity.[Result] The inhibition rate of extract on the germination rate of 4 varieties was all less than 20%,the inhibition rate of seed vigor index was all higher than 80%,that on seedling length was all above 70%.The inhibition rate and germination index of Thailand Jiadouwang with disease resistance was the biggest,being 71% and 65% resp.After the treatment by garlic extract,the conductivity and POD activity of the seedlings were increased significantly.The POD activity of Anshu Jiandouwang with high yield and Chiyu 5 were increased by 69% and 68% resp.[Conclusion] Alleochemicals in garlic had a strong inhibition on the seed germination of the kidney bean. |
