不同品种矾根叶色素含量与叶色参数的关系
|
摘要
以7个矾根品种为试材,对其叶绿素、类胡萝卜素、花色素苷及叶色参数(a*、b*、L*、C*)进行分析测定。通过多元逐步回归分析不同品种矾根叶色素含量与叶色相关性,结果表明:不同品种矾根叶绿素含量与色相a*成负相关,花色素苷与色相a*成正相关;b*、L*和C*均与叶绿素和花色素苷含量成负相关;各叶色参数与类胡萝卜素含量无显著相关性,未被引入各回归方程。进一步分析表明叶绿素a、花色素苷与叶色参数显著相关(P<0.05),叶绿素b与b*显著相关(P<0.05),与其他叶色参数无显著相关性,类胡萝卜素与各叶色参数无显著相关性。综合研究表明叶绿素a和花色素苷对矾根叶色的形成具有显著影响,叶绿素b与类胡萝卜素对各叶色参数无显著影响。
The parameters of chlorophyll, carotenoid, anthocyanin and leaf color(a*, b*, L*, C*) are analyzed with seven kinds of Heuchera micrantha. Multipal stepwise regression analysis is carried out on the correlation of the content of chlorophyll and leaf color. The results show that the chlorophyll content of different varieties is negatively correlated with Hue a, and anthocyanin is positively correlated with Hue a. Chlorophyll and flower pigment glycosides and b *, L * and C * have a negative correlation respectively. All leaf color parameters and carotenoids have no significant correlation and are not introduced into the regression equation. A further study shows that Chlorophyll a, flower pigment glycosides have a significant correlation with the leaf color parameters(P<0.05), that Chlorophyll b has a significant correlation with b*(P<0.05)and no significant correlation with the rest of leaf color parameters, that carotenoid has no significant correlation with every leaf color parameter. Comprehensive studies show that Chlorophyll a and anthocyanin have a significant influence on the formation of Heuchera micrantha leaf color, and Chlorophyll b and carotenoid have no significant effect on leaf color parameters.
