摘要
对不同继代刺梨株间的果实重量、可溶性固形物和可滴定酸的含量、种子的百粒重等性状的研究发现，继代繁殖数超过３０代，果实大小的整齐度明显降低，其它果实性状在观测的各继代株间整齐度都很高。同时也发现继代数越多，白粉病的发病率越低。
The comparison of fruit weight, T S S contents, titrating acid, and 100 kernel weight among the plants from different generations has been done The results showed as follows The size of the fruit from the plants propagated over 30 generations varied obviously, but other characters kept very high neat degree It was discovered that the more generations did it propagate, the lower incidence did powdery mildew occur
