摘要
2009—2012年连续4axe仙居仙油茶(Camelia olffera)进行优树选择,以选出适合本地生长的油茶优树。结果表明:共决选出油茶优树5株;5株油茶优树属霜降籽,中花类型,树冠开张,生长良好,抗病虫能力强;果实大小、分布均匀,每株平均产鲜果6.69~15.04kg,平均冠幅产鲜果1.27~2.07kg/m2,最少年份在0.53kg/m2以上;冠幅产油85.96~134.77g/m2,折合产油601.5~934.5kg/hm2;鲜出籽率43.4~47.06%,干出籽率25.83~32.01%,种仁含油率42.23%~46.4%,果油率6.27~8.46%;不饱和脂肪酸的油酸和亚油酸含量86.69%~89.64%,酸价0.21~0.32。
Selection of plus Camellia oleifera trees were implemented by reported, observation and determination at camellia plantations in Xianju, Zhejiang province from 2009 to 2012. 5 plus-trees were finally selected. They had characteristic of medium flower, opening crown, good growth, strong resistance to insect and diseases. These plus-trees had even fruit weight and distribution. The average yield of fresh fruit was 6.69kg-15.04kg/tree, 1.27kg-2.07kg per square meter of crown diameter, above 0.53kg per square meter of crown diameter by the least year. Their oil product per square meter of crown diameter reached 85.96-134.77g, about 601.5-934.5kg/ha. Fresh seed rate of above-mentioned plus-trees was 43.4 -47.06%, dried seed rate 25.83-32.01%, oil content of kernel was 42.23%-46.4%, that of seed was 6.27-8.46%. Oleic and linoleic acid content of unsaturated fatty acid was 86.69%-89.64%, with acid value of 0.21-0.32.
