摘　　要：[目的]研究马尾松无性系结实规律。[方法]采用球果称重法。[结果]马尾松同一无性系结实量,在2005、2006、2007年平均单株结实量差异极显著;在14个不同无性系中,无性系岑12(a12)结实量与无性系黄10(a2)结实量两者间存在极显著差异。[结论]马尾松不同无性系在不同年度平均单株结实量差异显著。[Objective] To study the seed bearing rules of clones of Pinus massoniana.[Method] Cones weighting method was adopted.[Result] The per stem average seed bearing amount of the same clone of Pinus manssoniana showed very significant difference among the years of 2005,2006 and 2007,of the 14 different clones,extremely significant difference could only be seen between the seed bearing amount of clone a12 and clone a2.[Conclusion] The per stem average seed bearing amount of different clones of Pinus massoniana was significantly different at different years.
