摘　　要：以一年生火祭(Crassula capitella‘Campfire’)叶插苗为试验材料,研究其在白光、红光、蓝光和紫外光4种不同光质处理3个月后,光质对火祭叶片色彩色差、叶绿素及花青素等含量的影响,并以此分析光质对火祭叶片呈色的影响。结果表明,不同光质在火祭叶片呈色过程中起关键作用。其中,紫外光对火祭叶片的色差和红色饱和度影响最大,并且有效提高了叶片中类胡萝卜素和花青素的含量,对火祭优良呈色的促进效果最好。Taking the leaf cutting seedlings of annual Crassula capitella‘Campfire’as materials,the effects of light quality on color difference,chlorophyll and anthocyanin content of annual Crassula capitella‘Campfire’leaves were studied after three months of treatments with white light,red light,blue light and ultraviolet,then the effects of light quality on the coloration of the Crassula capitella‘Campfire’leaves were analyzed.The results showed that different light quality was important in the coloration process of Crassula capitella‘Campfire’leaves.Among them,ultraviolet had the greatest effect on the color difference and red saturation of Crassula capitella‘Campfire’leaves,and effectively increased the content of carotenoids and anthocyanins in leaves,and had the best effect on promoting the color of Crassula capitella‘Campfire’leaves.
