研究中国福建、云南、台湾和巴西来源金线莲的生长与品质差异,结果表明:金线莲生长情况来源地优劣顺序:台湾>福建>巴西>云南;多糖含量:福建(台湾)>巴西>云南;总黄酮含量:福建>云南(台湾)>巴西;总生物碱含量:云南(巴西)>福建>台湾;氨基酸含量:云南>巴西(台湾)>福建。金线莲产量与茎粗和叶片数呈显著正相关,生物碱含量与茎粗呈显著负相关、与叶片数呈极显著负相关。
The results showed that: the order of the origin of the growth of A. japonica: Taiwan> Fujian> Brazil> Yunnan; polysaccharide content: Fujian (Taiwan)> Brazil > Yunnan; total flavonoids content: Fujian> Yunnan (Taiwan)> Brazil; total alkaloid content: Yunnan (Brazil)> Fujian> Taiwan; amino acid content: Yunnan> Brazil (Taiwan)> Fujian. There was a significant positive correlation between yield and stem diameter and leaf number, alkaloid content and stem diameter were significantly negatively correlated, and leaf number was extremely significant negative correlation.
