马尾松10个家系的发芽试验表明：种子发芽时间和子叶展开时间存在家系间的差别，发芽率屯存在明显的家系间差异；不同家系抗猝倒病能力存在明显的差别。不同家系生长差别很大，总体上闽北种源比闽西南种源好。马尾松一年幼苗的主要成份是叶（占50％以上），其次是根，茎量最少。 The germination tests of 10 pedigrees in Masson pine showed that there existed inter-family differences in seed germination time and cotyledon expansion time, and obvious differences in germination rate between different families were observed. Different families have very different growth. Generally speaking, the provenances in northern Fujian are better than the provenances in southwest Fujian. The main component of Pinus massoniana seedlings in one year is leaves (accounting for more than 50%), followed by the roots and stems the least.
