3种植物生长调节剂对发草种子萌发和幼苗素质的影响摘要：本试验以发草种子为实验材料，研究了用不同浓度的赤霉素（GA3）、生长素（IAA）以及烯效唑（S-3307）浸种对发草种子萌发和幼苗素质的影响。结果表明：赤霉素和生长素浸种处理对发草种子的萌发和幼苗素质均有明显的促进作用。此外综合分析不同处理对发草幼苗相关的形态指标和生理指标的影响之后，发现50mg/L的赤霉素（GA3）处理对发草种子萌发和幼苗素质的促进最为明显。关键词: 生长调节剂，发草，种子萌发，幼苗素质Influence of the Three Kinds of Plant Growth Regulator on Seed Germination and The Quality of Seedling of DeschampsiaSeed Science and Engineering 2006-2: Liu MingmingDirected by Shi HaichunAbstract：In this study, Using Deschampsia seeds as the experimental
