红松不同种源种子储藏后对苗木生长的影响

Effect of Pinus koraiensis Seeds Stored on Seedling Growth from Different Areas

红松是东北地区的重要造林树种之一,主要依靠培育实生苗造林。育苗中经常采用陈年种子,经对6个种源、7个批次的红松种子进行1年生苗木生长情况的测定,认为红松不同种源种子的储放时间长短与苗木生长的变化关系差异极显著;结果表明,有好的种源做保证,有利于苗木正常地生长。

Pinus koraiensis is one of major planting tree species in the northeast of China, and the stored seeds are usually used to cultivate seedlings for planting. An experiment was conducted to study the growth of one-year-old seedlings of Pinus koraiensis with the seeds from 6 provenances and 7 seedlots, the results showed that there were significant differences between storage period of Pinus koraiensis seeds from different areas and their growth performance, and the seedlings can grow well with the security of fine provenances.
