| 摘 要： | 对云南野生油料树种硬核（ Scleropyrum wallichianum ）4个县7个群体80株树的种子进行群体变异分析。结果表明：硬核种子大小在群体内的平均表型变异占93．72％，而群体间平均表型变异占6．28％。7个群体海拔分布范围为1100～1580 m，群体间平均种子长为22．27～24．70 mm，平均种子宽为17．91～20．28 mm，平均单粒种子质量为3．17～4．33 g，海拔越高，种子越小。种子形态和种皮刻纹深浅等质量性状受环境影响较小。

Phenotype Variations of Seed in Wilding Scleropyrum wallichianum |
| |
| Abstract: | Field investigation and sample collection of wilding oil-bearing tree Scleropyrum wallichianum were conducted in four counties, Yunnan.Based on the date of seeds from 80 individuals in 7 natural forest populations, its phenotype variations was investigated.There were larger variation within population ( 93.72%) and smaller variation ( 6.28%) among popula-tions.The average single seed length, diameter and weight variation ranges were 22.27-24.79 mm, 17.91-20.28 mm and 3.17-4.33 g, respectively, in 7 populations at 1 100-1 580 m.The seed from high altitude were smaller than those from low altitude.Vein of shell and shape of seed was affected slightly by environmental factors. |
