摘要：对腾冲红花油茶自然果实类型进行了调查,依据果型指数(果高/果径),将腾冲红花油茶的果实类型分为长果茶群(果高/果径>1)、圆果茶群(果高/果径≈1)和扁果茶群(果高/果径<1)三大类群。同时,依据果实形态特征细分为橄榄形、梨形、桃形、球形、柿饼形、五星形等30个类型;对各类型的果形特征及种实经济性状的变异进行了分析,结果显示:各类型间果实性状指标差异显著,果实形态性状与果实经济性状间存在一定的相关,其中,果皮厚度与出籽率呈显著负相关,果高及果型指数与干籽含油率存在一定的负相关。腾冲红花油茶果实为橄榄果、平顶桃形果、平顶三角柿饼果、三心麻桔果、突顶柿饼果、小薄饼果、菊瓣果等7种自然变异类型出籽率和含油率较高,是理想的油用果形;而纺锤果、五星柿饼果、金色柿饼果、蟠桃果以及菊瓣果等5种类型的果实形状独特,可作为观果油用兼用品种。
Different fruit types of Camellia reticulate were investigated.And three groups included long-fruit group （fruit shape index 〉 1）,round-fruit group（fruit shape index ≈ 1） and flat-fruit group （fruit shape index 〈 1） were divided based on fruit shape index （height/diameter）.About 30 types including olive,pear,peach,ball,dried persimmon,five-pointed star and so on were obtained according to difference of morphological characteristics.Fruit shape and economic characteristics variation of every type was analyzed.The result showed that significant difference of fruit characteristics was found among different types and there was a certain correlation existed between morphological characteristics and economic characteristics.Pericarp thickness exhibited a significantly negative correlation with the rate of seed.And a certain negative correlation was found between fruit height,fruit shape index and dry seed oil content.The seed ration and oil content were higher in 7 natural variation types including olive,flat-topped peach,flat-topped triangle persimmon,three-heart orange,dried persimmon,thin pancake,and daisy.And five types fruit shape including spindle,five-pointed star dried persimmon,golden dried persimmon,flat peach and daisy could be used for both oil and ornamental due to their curious shape.
