摘要
通过在新西兰罗托鲁阿(Rotorua)林科所苗圃,播种我国广西源的马尾松及新西兰辐射松种子的试验,观测其发芽和一年生苗木生长规律。结果表明,马尾松种子能在该地正常发芽出土。一年生苗木也能在该地正常生长。两个树种相比较,辐射松苗木的苗高、地径和干重生长都远高于马尾松,但两个树种种子发芽及一年生苗木生长的规律却基本相似。
Pinus massoniana seeds from Ningming County, Guangxi in China, together with pinus radiata seeds from New Zealand were sown in the Forest Research Institute nursery, Rotorua in New Zealand. The objective was to observe germination and growing pattern of the seeds and 1-year-old seedlings. The results of the trial show that Pinus massoniana seeds have normal germination and emergence, and that the seedlings also grow normally in the area. Compare pinus massoniana with pinus ladiata, the rate of increase in seedling height, root collar diameter and dry weight of the former was much lower than the latter, but the germination and growing pattern of pinus massoniana seeds and seedlings was similar to pinus radiata.
