摘要
在文冠果主要分布区采集文冠果种子,并对种子性状数量指标包括种粒长度、种粒直径、种粒质量、种皮质量、种仁质量、种仁体积、种粒体积、种子出仁率等进行测试,对其各性状之间的相关性分析表明,文冠果种粒各性状指标均有较大的变幅,而这种变幅说明了文冠果种粒个体间存在着较大的变异。从种粒各性状的相关性来看,除了种粒长度与种粒直径的线性关系不显著外,其他性状指标均具有显著线性正相关。
Xanthoceras sorbifolia seeds were collected in its main distribution areas.Some seed traits were determined,including length,diameter and weight of seeds,weight of seed coats and seed kernels,volume of seed kernels and seeds,kernel content in seed,etc.Correlation analysis shows that all the seed traits of X.sorbifolia are significantly different among different distribution areas,indicating an obvious variation in seed size and weight.Except for the unobvious linear correlation between seed length and seed diameter,there are significant positive linear correlations between all the other seed traits.
