摘要:
 对毛梾种子萌发及幼苗生长规律进行了研究，为种子的繁育提供理论依据。采用称重、测量、解剖、TTC法及内含物测定等方法，分别对不同种源地种子形态结构、活力、内含物含量进行测定，研究不同种源间种子萌发特性差异。采用低温层积、激素处理、不同基质处理相比较及定株观测的方法，研究解除种子休眠的有效技术及毛梾幼苗生长节律。结果表明：6个种源地间以陕西杨陵种源为最优种源，河南种质资源最差；陕西杨陵种源采用室外低温层积催芽效果最好，发芽率达46.7%(为直接播种的114倍)；使用激素处理以150 mg·L-1 GA3的处理最为有效(发芽率达到48.43%)；发芽基质以蛭石最好。毛梾幼苗2个生长高峰期分别为5月下旬到6月上旬和7月底到8月上旬。
