通过对杉木种子园无性系不同分株自由授粉子代８年的试验观察和分析结果表明：在树高、胸径和材积等生长性状上，不同无性系后代生长呈现极显著差异；而无性系内各分株间的后代生长差异均不显著；但各分株后代生长均比相应无性系所有混合种子后代生长好。子代年生长量的分析表明：在年度间、无性系及无性系不同分株间均呈现极显著差异，年度和无性系间交互效应明显，而年度和无性系分株间交互效应不显著；从８年的生长规律发现，种子园无性系分株间生长表现出较高的一致性。
Eight years of free pollination progeny from different ramets of Chinese fir seed orchard were observed and analyzed. The results showed that there were significant differences in the growth of offspring of different clones on growth traits such as tree height, DBH, There was no significant difference in the offspring growth between the ramets; however, the offspring of all the ramets grew better than the progenies of all the mixed seeds of the corresponding clones. The analysis of annual growth of offspring showed that there was a significant difference between clones and clones in different clones during the year, and the annual and clonal reciprocal effects were obvious, while the interaction between annual and clonal ramets was not significant. According to the growth pattern of eight years, the growth of clonal ramets in seed orchard showed higher consistency.
