分析比较了龙眼各营养器官之间、同品种不同结果母枝类型间、同品种不同植株之间、不同龙眼品种之间的多糖含量。结果表明:龙眼各营养器官皆含有多糖成分,且差异显著,依次为叶(4.575%)>新梢(1.928%)>枝条(1.644%)>根(0.918%);同一营养器官仅在不同成熟期的部分龙眼品种间多糖含量存在显著差异。
The contents of polysaccharide in different longan cultivars among different vegetative organs of longan, different parental types of the same variety, different plants of the same variety, and different longan varieties were analyzed and compared. The results showed that all the vegetative organs of longan contained polysaccharides with significant differences, which were leaf (4.575%)> shoots (1.928%)> shoots (1.644%)> roots (0.918% There were significant differences in polysaccharide content among some longan varieties.
