摘要
为了选育食用、油用及药用价值较高的白木通品种,对8个不同地理种源白木通的果实经济性状、果肉营养成分、藤条药用成分、种子含油率及脂肪酸组成相关指标进行了方差分析和多重比较。结果表明:(1)种源间的果实性状中各指标均存在显著性差异。安徽省宁国县军天湖乡天湖街道种源的可食率较高,超过30%,单果质量和果肉质量均最大,分别为276.64 g和84.82 g,显著高于其它7个地理种源,具有较高的食用价值。(2)种源间种子含油率及脂肪酸组成除不饱和脂肪酸外均存在显著性差异。安徽省宁国县军天湖乡天湖街道种源的含油率最高,为47.09%,不饱和脂肪酸的含量也较高,为72.61%,具有较高的油用价值。(3)种源间果肉营养成分性状存在显著性差异。江西省九江市东林寺东林村种源的总糖和还原糖含量最高,分别为32.35%和16.31%,显著高于其它7个地理种源,总酸及维生素C含量中等,果肉营养价值较高。(4)种源间藤条药用成分存在显著性差异。重庆市武隆县仙女乡白果村种源的齐墩果酸B含量最高,达到0.6%,显著高于其它7个地理种源,且其藤条的总药用成分含量最高,具有较高的药用价值。
Some related indexes of fruit economic characters, flesh nutritional components and rattan medicinal components, seed oil content and fatty acid composition inAkebia trifoliata （Thunb.） Koidz. subsp. australis （Diels） T. Shimizu from eight different geographical provenance were analyzed by the methods of variance analysis and multiple comparisons, to breed ifne varieties with high edible value, oil-used value and medicinal value. The results showed that there were signiifcant differences of fruit economic characters inA. trifoliate （Thunb.） Koidz. subsp. australis （Diels） T. Shimizu between the eight geographical provenances. The fruit edible rate of the plants from Tianhu Street, Juntianhu Town, Ningguo County, Anhui Province was higher than others, more than 30%. The single fruit mass and lfesh mass from the provenance were significantly higher than the others, which respectively reached 276.64 g and 84.82 g, so its edible value was higher. The seed oil contents and fatty acid compositions in A. trifoliata（Thunb.） Koidz. subsp. australis （Diels） T. Shimizu had signiifcant differences between the eight geographical provenances except unsaturated fatty acid content. The oil content of the plants from Tianhu Street, Juntianhu Town, Ningguo County, Anhui Province was the highest, and reached 47.09%. The unsaturated fatty acid content of the plants was higher than the others, and reached 72.61%, so its oil-used value was higher. The lfesh nutritional components inA. trifoliata （Thunb.） Koidz. subsp. australis （Diels） T. Shimizu had signiifcant differences between the eight geographical provenances. The total sugar and reducing sugar contents of the plants from Donglinshi Village, Donglinshi Township, Jiujiang City, Jiangxi Province were signiifcantly higher than the others, which respectively reached 32.35% and 16.31%, and its total acid content and vitamin C content were medium, so its fruit nutrient value was higher. The medicinal components inA. trifoliata （Thunb.） Koidz. subsp. australis （Diels） T. Shimizu had signiifcant differences between the eight geographical provenances. The phenylethanoid glycoside B content of the plants from Baiguo Village, Xiannv Town, Wulong County, Chongqing City was signiifcantly higher than the others and reached 0.6%, and its total medicinal component content was the highest, so its medicinal value was higher.
