| 摘 要： | 以21个种源的种子为材料,研究了盐肤木种子形态性状在种源水平上的遗传变异规律。研究结果表明:盐肤木种子形态性状在不同种源间存在极显著差异,但主要由环境因素引起,不能比较稳定的遗传;盐肤木种子大小表现出明显的经纬度地理变异模式,且降雨量越小,气温越高,其种子饱满度越高。盐肤木种子长、种子厚和种子千粒重之间显著正相关。

| Abstract: | Using the seeds of 21 provenances as materials,the genetic variation of morphological traits of seeds of Rhus chinensis Mill.was studied at the provenance level.The results were revealed as following:There was highly significant difference among different provenances.However,the environmental factor could cause the unstable inheritance.The geographic variation pattern of latitude and longitude was found in seeds.The temperature higher and the rainfall small,the seed plumpness was higher.There was significantly positive correlation among the length,the thickness and thousand seed weight of seeds. |
