大蒜浸提液对辣椒种子发芽和幼苗生长的影响

[目的]探讨大蒜素在蔬菜育苗上的应用效果，为无公害蔬菜生产培养壮苗寻找新的途径。[方法]用不同浓度的大蒜浸提液处理辣椒种子，研究大蒜浸提液对辣椒种子发芽和幼苗生长的影响。[结果]对照种子的发芽高峰出现在第4天，发芽种子41粒。25和35ml／L大蒜浸提液处理的种子在第4天只有2粒发芽，其发芽高峰出现在第6天。5和15彬L大蒜浸提液处理的种子的发芽高峰出现在第5天。25和35ml／L大蒜浸提液处理的种子的发芽势分别比对照降低2，4．1％和32．9％。15、25和35ml／L大蒜浸提液处理的种子的发芽指数分别比对照降低22．1％、25．7％和28．3％。大蒜素处理对辣椒幼苗的延长生长有一定的抑制作用，对加粗生长有一定的促进作用。[结论]大蒜素对辣椒种子发芽有一定的抑制作用，对辣椒幼苗生长有一定的促进作用。

Effects of Garlic Extraneous Liquid on the Seed Germination and Seedling Growth of Pepper

[Objective] The research aimed to discuss the application efficacy of gralicin on vegetable seedling so as to search for new approaches of cultivating sound seedlings for producing uncontaminated vegetable.[Method] The pepper seeds were treated with different concn.of gralic extraneous liquid to research its effects on the seed germination and seedling growth of pepper.[Result] The germination peak of seeds in CK appeared on the 4th day and there were 41 seeds germinated.Among the seeds treated with 25 and 35 ml/L gralic extraneous liquid,there were only 2 seeds germinated on the 4th day and their germination peak appeared on the 6th day.The germination peak of seeds treated with 5 and 15 ml/L garlic extraneous liquid appeared on the 5th day.Compared with CK,the germination potentials of seeds treated with 25 and 35 ml/L garlic extraneous liquid were reduced by 24.1% and 32.9% resp.and the germination indices of seeds treated with 15,25 and 35 ml/L garlic extraneous liquid were reduced by 22.1%,25.7% and 28.3% resp.The treatment with gralicin had some inhibitroy action on the elongation growth of pepper seedlings and some promoting action on their thickening growth.[Conclusion] Garlicin had some inhibitory action on the seed germination of pepper and some promoting action on its seedling growth.
