黄山青冈种子形态变异的初步研究

A preliminary study on the morphological variation of seeds of Cyclobalanopsis glauca populations of Huangshan

该文对黄山西坡两个青冈种群种子的形态变异进行了初步研究。结果表明种群内种子的变异主要来自于各单株内，是由于环境因子差异所致。两个种群种子重量差异显著，可能是由于两种群的更新方式不同的缘故，至于是否具遗传原因，尚待进一步研究。

Two popualtions were chosed to study the morphological variation of the seeds. Results suggestthat the variation of intrapopulation mainly comes from the variation of intraplants, and the variationof intraplants is caused by the heterogeneity of the environmental factors. The mean weight of seedsvaries significantly between the two populations, it is thought to relate with the different ways of regeneration of the populations. Whether it is a genetical trait remains unknown, and need further research.
