【摘要】 在通过目测初选出的41株优良单株中,以茶树油国际标准(ISO4730-1996)为基准,以枝叶生物量、含油率、4-松油烯醇和1,8-桉叶油素含量为评价指标,运用独立标准选择法,复选出14个高精油优良单株。用多目标决策法将优良单株分为3个等级(1级5株、2级3株、3级6株)。8株精选的优良单株,其生物量为230.86-147.32 g.株-1,为群体平均值的2.87-1.83倍;其含油率达1.51%-1.15%,为群体平均值的1.70-1.29倍,选择增益明显。更多还原

【Abstract】 There were 41 superior individuals selected out primarily through observation by eyes.Based on international criteria of tea-oil,there were 14 superior individuals screened out,with biomass of branches and leaves,content of tea-tree oil,content of terpinen-4-ol and 1,8-cineloe as the indexes.By method of polygonal decision,14 superior individuals were defined into 3 grades,5 individuals were grade Ⅰ,3 individuals were grade Ⅱ,6 individuals were grade Ⅲ.The biomass of branches and leaves of 8 superior individuals were 230.86-147.32 g per individual,which were 2.87-1.83 times of the average values,content of tea-oil reached 1.51%-1.15%,which was 1.70-1.29 times of the average values,and the gain by selection was very significant.更多还原
