摘要：以13个产地居群的山桐子果实为材料,测定其全果含油率,并选取5个居群的果实分别测定果肉、种子含油率进行变异分析。结果表明:(1)13个居群间山桐子果实含油率差异显著,四川各居群山桐子果实含油率明显大于其他地区,各个居群内果实含油率差异明显,极端变异程度较大。(2)5个居群山桐子果肉含油率均大于种子含油率,而果肉含油率变异系数及相对极差均小于种子。(3)聚类分析结果显示,朝天等7个居群聚为一类,其果实含油率较高,变异系数较小,可以作为进一步良种选育的材料;海拔等地理因素对山桐子果实含油率均有一定影响,但程度不一。(4)5个居群山桐子果实油脂折光率均较高,而酸值均较低,表明山桐子油品质好,纯度较高,而且不同居群山桐子油碘值差异显著,反映其油脂不饱和程度差异明显。
Oil content of whole fruit were determined using fruit of Idesia polycarpa Maxim. from thirteen populations,and oil contents of pulp and seeds were determined using the fruit from five population. The results were as follows： （1）There were significant differences in oil contents of whole fruit among thirteen populations,and the oil contents of fruit from populations in Sichuan Province were obvious greater than those from other populations,in addition. There were also significant differences in oil contents of fruit in each population,and degree of extreme variation were large. （2）Oil contents of pulp from the five popula- tions were greater than those of seeds, while coefficient of variation and relative range of pulp were less than seeds. （3）Clustering analysis indicated that oil contents of fruit from seven populations included chaotian et al. were greater than that of others,and coefficient of variation of them were less than that of others. These populations were clustered to a class and could be as materials for further breeding. Geographical factors such as elevation and so on had different levels of effects on oil contents of fruit. （4）Refractive index of fruit oil from five populations were higher,while acid value were lower,which indicated that oil of I. polycarpa had excellent quality and high purity. There were significant differences in Iodine value of I.polycarpa oil from different populations, which reflected the obvious difference of degree of unsaturation of oil.
