摘要
以库拉索芦荟为试验材料,采用透射电子显微镜及HPLC技术,研究了增强UV-B辐射对芦荟的超微结构和蒽醌类物质的影响.结果显示:增强UV-B辐射20d,每天处理6h,芦荟叶中总蒽醌、芦荟素、芦荟大黄素的含量分别增加了31.8%、11.3%和22.0%;叶绿体被膜有轻微破损,其他细胞器结构没有明显变化.说明增强UV-B辐射能促进蒽醌类物质的积累,但对细胞超微结构影响不大.
By using transmission electron microscopy and high performance liquid chromatography,this paper studied the effects of enhanced UV-B radiation on the leaf anthraquinones content and cell ultrastructure of Aloe vera L.After treated with enhanced UV-B radiation 6 hours per day for 20 days,the total anthraquinone content,barbaloin content,and aloe-emondin content in A.vera leaves increased by 31.8%,11.3%,and 22.0%,respectively,chloroplast envelope membrane was slightly damaged,but the structure of other organelles had no significant change.It was suggested that UV-B radiation could promote the accumulation of anthraquinone in A.vera leaves,but had less effects on the leaf cell ultrastructure.
