外源激素对野生蔬菜实葶葱种子萌发的影响

为更好地使激素在实葶葱种子处理上得到应用，以新疆野生蔬菜实葶葱种子为材料，利用不同浓度的GA3、NAA和6-BA溶液对实葶葱种子进行浸种处理，研究了不同浓度外源激素对实葶葱种子萌发的影响。结果表明：3种外源激素处理对实葶葱种子萌发的影响存在较大差异，50～1200mg·L-1GA。能不同程度地促进实葶葱种子的萌发，其中以浓度为200mg·L-1GA。处理的效果最佳，发芽率为85．33％，高于对照9．33个百分点；120mg·L-1的NAA处理对实葶葱种子的萌发有一定的促进作用，但不明显；5～120mg·L-1 6-BA处理抑制实葶葱种子萌发。

Effects of Exogenous Hormone on Seed Germination of Allium galanthum L.

In order to apply the hormones on the Allium galanthum L. seeds better,taking Xinjiang wild vege- table Allium galanthum L. seeds as material,Allium galanthum L. seeds were soaking in different concentra- tions of GA3, NAA and 6-BA solution,the effects of different concentrations of exogenous hormones on germi- nation were researched. The results showed that there was a big difference between the three kinds of exoge- nous hormones on the germination impact of Allium galanthum L. seeds. 50~ 1 200 mg.L-1 GAs promoted the seed germination in different degrees, the best effect was at the concentration of 200 mg. L-1, germination rate was 85.33% and was significantly higher than the control for 9.33 percent 120 mg.L-1 NAA had a certain promoting for seed germination,but not significant 5 - 120 mg. L1 6-BA couldn＇t significantly promote the seed germination,but inhibited seed germination.
