【摘要】 采用分光光度法等对不同温度条件下红花檵木叶片中的色素含量进行测定.结果表明:随着叶龄的增长,红花檵木叶片的叶绿素含量不断累积增加,类胡萝卜素亦呈波状上升趋势,加温处理的红花檵木叶片中花色素苷含量却都有不同程度的下降.因此,栽培中若能选取有充足阳光照射、温度又不至过高的小气候条件,则能相对长时间的保持红花檵木鲜艳的玫瑰红色,减缓花色素苷降解的速度.更多还原

【Abstract】 Using spectrophotometry and determinates the pigment content in Loropetalum chinesevar.rubrum leaves under different temperature conditions.The results show that: With leaf growth,its chlorophyll content will continue to cumulate and increase,its carotenoids content will increase as wavy upward trend,but its anthocyanin content decline in varying degrees.Therefore,in cultivation,selecting the small climatic conditions with sufficient sunlight and moderate temperature will make Loropetalum chinesevar.rubrum maintain bright red roses for a relatively long period and delay the speed of anthocyanin degradation.更多还原
