马尾松是福建省最重要的用材树种。本文对马尾松的群体和个体的遗传变异进行分析研究, 目的在于发掘当地树种的遗传资源,科学地制定马尾松的遗传改良程序,以及为当前林业生产中种子调拨和建立采种基地等工作提供依据。 1979年,共采集种子样本73份,包括全国不同产地、省内不同林分,同一林分不同家系和不同海拔高度的林分。1980年,于洋口,官庄林场作苗期比较。观测项目有种子大小,重量、发育程度、苗木高度,地径。封顶率和其它性状。根据试验结果,本文对各种变异类型做出了评价,并对福建省内马尾松的遗传改良程序提出初步意见。
Masson pine is the most important timber species in Fujian Province. This paper analyzes the genetic variation of population and individual in Masson pine, aims to explore the genetic resources of local tree species, scientifically establish the genetic improvement program of masson pine, and provide the basis for the current seed production allocation and establishment of seed production bases in forestry production . In 1979, a total of 73 seed samples were collected, including different producing areas in the country, different types of forests in the province, different families in the same forest, and stands at different altitudes. In 1980, in Yangkou, Guanzhuang forest seedling comparison. Observed projects have seed size, weight, degree of development, seedling height, diameter. Cap rate and other traits. According to the test results, this paper evaluates various types of variation and puts forward preliminary opinions on the genetic improvement program of masson pine in Fujian Province.
