| 摘 要： | 从杉木林中采集七株优树的种子，并在种子园内采集相同优树无性系自由授粉种子，进行成对对造林比较试验，造林四年后，来自种子园的后代其生长量显著高于来自林分的后代，树高增长9．1％，胸径增加14．5，由此，对杉木初级种子园的遗传效应加以肯定并进行评论。

| Abstract: | The seven pairs of open-pollinated progenies of plus trees in individual plantations and of their relative clones in a seed orchard of Chinese fir have been tested. Four years after having been planted in the field, significant growth difference was found between progenies of both pollin resource types to the same female parent genotypes. The growth of all the progenies from the clones in the seed orchard have exceeded those from their plus trees in plantations,having an average gain of 9.1%(4.7%~14.1%) for height and 14.5%(9.9%~23%) for DBH. This result would verify the genetic improvement effect of elementary seed orchard of Chinese fir. |
