Effects of Alleochemicals in Garlic Extract on the Seed Germination of Kidney Bean
[Objective] The research was to study the allelochemicals intensity of the garlic extract on the seed gemination of kidney bean. [Method] The girlic 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] Alleo-chemicals in garlic had a strong inhibition on the seed germination of the kidney bean.
