探究6个紫薇品种不同试验阶段的叶片色素变化规律，以“紫精灵、红火箭、紫莹、赤红、丹红、玲珑红”6个紫薇品种为实验材料，比较不同时期紫薇叶片的色彩参数L~*、a~*、b~*值以及叶绿素a、叶绿素b、类胡萝卜素质量分数和花色素苷含量。结果表明，紫薇叶片明度(L~*)值变化不大，而红度(a~*)、黄度(b~*)值变化明显。‘紫莹’‘丹红’‘赤红’3个紫叶紫薇品种的a~*显著降低(P

In order to understand the change regularities of leaf pigment in different growth stages,6 cultivars of Lagerstroemia indica were taken as the research objects,including'Zi Jingling','Red Rocket','Zi Ying','Ebony Fire','Ebony Embers',and'Ling Longhong'.The values of color parameters,such as L*,a*,b*,the contents of chlorophyll a,chlorophyll b,carotenoids and anthocyanin were measured.The results showed that the leaf brightness(L*)values of all the 6 cultivars of L.indica changed little,while a*and b*changed significantly.The a*values of'Zi Ying','Ebony Embers'and'Ebony Fire'decreased signific...
