东北三省不同种源蒙古栎种子表型性状和淀粉含量对比分析

Quercus mongolica Seeds' Character and Starch Content Comparisons of Different Provenance in the Three Northeastern Provinces

对东北三省蒙古栎自然分布的4个主要地区的地理位置及主要气候因子进行调查分析。采用方差分析、Duncan’s多重比较和相关分析法对4个地区蒙古栎种子表型性状和淀粉含量进行分析。结果表明黑龙江省带岭的蒙古栎种源为品质优良的种源;蒙古栎种子随种子长度增大,单果重呈增加的趋势。

This paper investigated and analyzed geographic location and climatic factors of the four major natural distribution areas in the three Northeastern Provinces. Meanwhile, compared and analyzed the phenotype characters and starch content of Quercus mongolica seeds of the four areas by means of variance analysis, Duncan＇ s multiple comparisons and correlation analysis. The results showed that Q. rnongolica in Dailing of Heilongjiang Province has good quality sources. The greater the seed length, the heavier the fruit weight.
