摘　　要：以具有红光(660 nm)和蓝光(446 nm)复合光的LED灯作为光源,研究其对‘阳光红心’红掌组培苗生长和叶绿素荧光反应的影响。结果表明,70%红光+30%蓝光的复合光能显著提高红掌叶片叶绿素a和叶绿素b的含量,促进叶片和根茎的干物质积累,而30%红光+70%蓝光的复合光则更有利于叶面积的扩张。红蓝复合光能抑制红掌叶片暗适应初始荧光(Fo),增加原初光能转化效率Fv/Fm,提高过氧化物酶(POD)、过氧化氢酶(CAT)和超氧化物歧化酶(SOD)活性,降低叶绿素荧光产量,显著提高表观光合电子传递速率(ETR),改善光合作用系统Ⅱ(PSⅡ),促进叶片获取光能的能力,提高光合电子传递和光能转化效率,促进红掌叶片和根茎的生长。The effects of light on the growth and chlorophyll fluorescence of A nthuriun andraeartum ＇Yongonred＇ were studied under red and blue composite light of red LED （660 nm）and blue LED （446 nm）. The results showed that 70% red light and 30% blue light could significantly increase the content of chlorophyll a and chlorophyll b, and promote the accumulation of dry matter in the leaves and rhizomes, while the composite light of 30% red and 70% blue was even more conducive to the expansion of leaf area. Blue and red LED treatments reduced the minimal fluorescence （F o）, promoted the maximum quantum yield of PSII （Fv/Fm）, and significantly increased the photosynthetic electron transport rate （ETR） in comparison to the control. We hence concluded that blue and red LED treatments increased the ability of the leaves to photosynthesize indirectly through leaf expansion, chlorophyll concentrations accumulation, photosynthetic electron transport rate and light energy conversion efficiency improvement, and directly to promote the growth of leaves and roots of A nthurium andreanum.
