遮荫处理对‘血红鸡爪槭’叶片色素及碳水化合物含量的影响

Effects of shading treatments on pigment and carbohydrate contents in Acer palmatum 'Bloodgood' leaves

研究了不同遮荫处理对鸡爪槭的栽培变种‘血红鸡爪槭’叶片叶绿素、花色素苷以及糖和淀粉含量的影响,结果表明:随着光照强度的减弱,‘血红鸡爪槭’叶片中叶绿素a、叶绿素b、总叶绿素以及类胡萝卜素的含量都增多,但光强太弱含量反而会降低;叶片中花色素苷、糖以及淀粉含量随着光照强度降低而减少。

The effects of different shading treatments on the chlorophyll, cyanin, sugar and starch contents in Acer palmatum‘Bloodgood＇ leaves were studied, and the results showed that the contents of Chl a, Chl b, total Chl and carotenoid all increased as the intensity of illumination decreased, but the contents could reduced when the intensity was too low. The contents of cyanin, sugar and starch reduced with the intensity lowering.
