基于邱园种子库的顽拗性种子名录

Recalcitrant Seeds List Based on KEW Seed Bank Dataset

指出了顽拗性种子的分布与植物所属的科、属并无必然的关联,故其物种数量并无确切数字。根据英国皇家植物园(邱园)种子数据,依照APGⅣ分类系统,对公布贮藏特性的24781份种子数据进行了整理与分析。结果表明:依照最新的数据,共有顽拗性种子620种,分属于71科,237属。名录有了细微地扩大。对顽拗性种子的估算方法、顽拗性种子数量、生境等问题进行了讨论。以供参考。

Previous studies have shown that the distribution of recalcitrant seeds is not absolutely related to the families and genera of plants,so there is no definite number of those species.According to the seed data of the Royal Botanical Garden(KEW)and APG IV classification system,this paper analyzed totally 24781 seed storage characteristics data.The results showed that according to the latest data,there were 620 species of recalcitrant seeds,belonging to 71 families and 237 genera.The list has been slightly enlarged.The estimation methods of recalcitrant seeds,the number and habitat of recalcitrant seeds are discussed.
