香果树播种育苗技术研究

A Study of Seed Sowing and Seedling Raising of Emmenopterys henryi

  • 摘要: 本文采用随机区组试验设计,选择赤霉素(GA)、吲哚丁酸(IAA)、双吉尔(GGR)和温水浸种等4种处理方式开展香果树场圃播种育苗试验。研究表明,经赤霉素(GA)浸种处理后,香果树种子的场圃发芽率和发芽势分别可达33.80%和27.53%,出苗时间可提早25 d,成苗率和苗木生长效果最好;双吉尔(GGR)浸种处理的场圃发芽率和发芽势亦十分良好,分别达到31.00%和23.27%,但整体略次于赤霉素(GA)浸种效果;吲哚丁酸(IAA)浸种处理对提高香果树种子发芽率、出苗时间和幼苗生长具有较好促进作用;温水浸种也能一定程度促进香果树种子萌发和苗木生长。

     

    Abstract: In this study,four kinds of immersing approaches including GA, IAA, GGR and warm water were chosen to conduct the seed sowing and seedling-raising experiment of Emmenopterys henryi, which was designed in random blocks. The results showed that the seed immersed in GA grew better than other approaches with a highest germination rate of 33.80% and a germination trend of 27.53%, and this approach could accelerate the seed growth for about 25 days; The seed immersed in GGR also had a high germination rate of 31% and a germination trend of 23.27%, and was slightly below the GA group; IAA could promote the germination rate and seed growth,and warm water could accelerate seed germination and seedling growth to a certain degree.
