摘要
为筛选低镉积累的优质丹参新材料,以 7 份不同的丹参材料为研究对象,从农艺性状、有效成分含量、含水率、可溶性蛋白含量和镉积累特性方面进行评价.结果表明:D11 地下部分丹参酮类和可溶性蛋白含量均最高、丹酚酸B含量排第二;且地上和地下部分镉含量均最低、转运系数大于 1.相关性分析表明,地下部分镉含量与可溶性蛋白含量、镉转运系数均显著负相关;镉转运系数与可溶性蛋白含量显著正相关.综上所述,7 份丹参材料中丹参酮类和丹酚酸B含量较高的D11 具有低镉积累、抗逆性好的特征,是综合品质最优的新材料.
Abstract
In order to screen high-quality new materials of Salvia miltiorrhiza with low cadmium accumulation.In this study,7 different S.miltiorrhiza materials were evaluated in terms of agronomic traits,effective component content,water content,soluble protein con-tent,and cadmium accumulation characteristics.The results showed that the underground part of D11 had the highest content of tan-shinones and soluble proteins,with salvianolic acid B content ranking second;The cadmium contents in both the aboveground and un-derground parts of D11 were the lowest,with the transport coefficient greater than 1.The correlation analysis showed that there were significant negative correlations between the cadmium content in the underground part and soluble protein content,cadmium transport coefficient;The cadmium transport coefficient was significantly positively correlated with soluble protein content.To sum up,among the S.miltiorrhiza materials,D11 with high contents of tanshinones and salvianolic acid B had the characteristics of low cadmium ac-cumulation and good stress resistance,making it the new material with the best comprehensive quality.
