小陇山高桥林区野生七叶树种质资源调查及种子繁殖研究

The Investigation and Research of Wild Germplasm Resources of Aesculus chinensis Seeds in Xiaolongshan Forest Takahashi

七叶树是无患子目七叶树科,为世界著名的观赏树种之一。通过对野生七叶树资源及植物性状进行调查,基本确定了野生七叶树在小陇山高桥林区的分布及野生七叶树生境情况,明确了该树种的植物学特性。但个体数量与种群数量急剧下降,急需大力保护。并对种子繁殖出苗率不高现状进行研究,确立种子催芽方式及播种季节对七叶树苗木出土的影响。以期对野生七叶树进行保护、繁殖奠定基础。

The Buckeyes were Sapindales hippocastanaceae, for the world famous ornamental tree. Through investi- gation of the wild resources of Aesculus and plant traits, basically to determine the wild horse chestnut in Gaoqiao Xiaolongshan forest distribution and wild horse chestnut habitat situation, has been clear about the botanical charac- teristics of the species. But a number and population declines sharply, there is an urgent need for more efforts to protect. And on seed bred Seedling rate is not high status research, to establish the effect of seed germination and seeding season of Aesculus chinensis seedling unearthed. In order to protect the wild horse chestnut, breeding lay the foundation.
