不同处理方法对光叶红花苕种子发芽的影响

Effect of Different Treatment Methods on Seed Germination of Vicia villosa

研究了不同浓度硫酸、赤霉素处理和机械处理对光叶红花苕种子发芽势、发芽率和发芽指数的影响。结果表明:机械处理促进发芽效果最好,发芽势达92.00%;发芽率达94.00%;发芽指数达25.84;浓硫酸处理次之,以98%硫酸处理60 min效果较好,发芽势达77.33%;发芽率达86.00%;发芽指数达42.55;赤霉素处理种子,对发芽率影响不显著。由于机械处理操作难度大,因此,实际生产中用98%硫酸浸种60 min来提高种子发芽率较好。

The author studied the effects of different concentrations of sulfuric acid, GA treatment and mechanical treatment on germination potential, germination rate and germination index of Vicia villosa seed. The results showed that the effect of mechanical treatment was the best, and the germination potential was up to 92.00%, the germination rate was up to 94% ,the germination index was up to 25.84. For sulfuric acid treatment, it was better to soak the seed in sulfuric acid of the concentration of 98% for 60 minutes, and the germination poten- tial was up to 77.33% ,the germination rate was up to 86.00% ,the germination index was up to 42.55. GA had no significant effect on germination rate. As mechanical treatment was technically demanding, using the concentration of 98% sulfuric acid to soak the seed for 60 minutes was the easiest and most effective method in practical production.
