摘  要：
采用野外调查与室内分析相结合的方法,对雅安野生红花油茶资源进行调查研究。结果表明,调查区内红花油茶总面积为236.1 hm2,约3.4万株,但管理粗放,产量较低。在资源调查的基础上,通过初选、复选和决选,筛选出雅红11、雅红15、雅红17三个优良单株,鲜果重62.31 g～81.37 g、单位冠幅面积产果量2.5 kg.m-2～3.0 kg.m-2、鲜出籽率41.34%～43.17%、干出籽率25.14%～26.76%、干出仁率73.88%～76.54%、种仁含油率30.58%～32.46%。这些指标均达到了国家油茶优树选择标准。根据当地资源优势,提出了红花油茶资源保护与持续利用的建议。

摘  要：
The field investigation and laboratory analysis were made of the resource of Camellia polyodonta in Ya'an.The results showed that there were 34 455 individuals of Camellia polyodonta distributed in the survey area of 236.1 hm2.But its production was low because of the extensive management.Based on the germplasm resource investigations of Camellia polyodonta in this area,three high quality individuals including Yahong 11,Yahong 15 and Yahong 17 were sifted through preliminary,repeated and final selection.Their fresh fruit weight ranged from 62.31 g~81.37 g;the fruit yield of unit crown area was 2.5 kg·m-2~3.0 kg·m-2;the fresh and dry seed-producing rates were 41.34%~43.17% and 25.14%~26.76% respectively;the dry seed had 73.88%~76.54% of kernel rates;the oil extraction rate in the kernel was 30.58%~32.46%.All indicants of excellent tree had reached the selection criteria of national plus tree of C.Oleifera.According to local resource advantage,some suggestions were put forward for the protection and sustainable utilization of Camellia polyodonta resources.
