| 摘 要： | 目的]研究不同植物激素及浓度对羊草种子萌发和幼苗生长的影响。方法]用GA，、2，4-D、NAA和6-BA4种植物激素对2种羊草种子进行种子萌发试验，对天然生长的羊草幼苗进行幼苗生长试验。结果]植物激素GA，和6-BA对羊草种子发芽率的影响均表现为低浓度促进，高浓度抑制的趋势，并且均能促进羊草幼苗的生长，总体效果为GA3〉6-BA；而任意浓度的NAA和2，4-D对2种羊草种子的萌发和羊草幼苗的生长均表现不同程度的抑制作用。结论]不同植物激素对羊草种子萌发和幼苗生长产生不同的影响。

| Abstract: | Objective]To study the influence of different phytohormone and density over the germination and seedling growth of L.chinensis seeds.Method]Two L.chinensis seeds and one L.chinensis seedling were treated by four phytohormones of GA3,2,4-D,NAA and 6-BA.The germination of L.chinensis seeds and seedling growth were observed.Results] The results showed that GA3 and 6-BA were both promote the germination and seedling growth of L.chinensis seeds in low concentration,but inhibited their germination and growth i... |
