珍稀濒危树种庙台槭结实特性及播种育苗试验研究

Fruiting Characteristics and Sowing Seedlings of Rare and Endangered Species of Acer miaotaiense

对庙台槭野生种群结果母树的结实特性及果实形态特征和性状进行了调查和测定,对庙台槭种子的发芽特性及1~3年生播种苗的生长规律进行了试验观测.结果表明:群落光照不足是导致母树结实率低、种子有仁率低、质量差的重要原因,而种子质量差且发芽困难,也可能是该树种濒危的主要原因;1~3年生庙台槭播种苗在引种地表现出一定的速生性和对引种地的气候及土壤条件良好的适应性,可以在河南低海拔平原地区进行较大范围的区域引种试验和示范.

In this paper, the fruiting characteristics, fruit morphological characteristics and traits of wild populations of Acer miaotaiense were investigated and measured. The germination characteristics of the seeds and 1- 3 years＇ sowing seedling growth law were observed. The results showed community light deficiency was an important reason for the low seed setting rate and poor quality of the seed germination. The main reason for the endangered species was that the seed quality was poor and germination was difficult. A. miaotaiense seedlings of 1-3 years showed a rapid growth and a good adaptability of climate and soil condition in the introduction area. A wide range of regional introduction test and demonstration work could be done in low altitude plain area in Henan.
