摘 要 ：以‘京秀’葡萄为试材,研究了蓝膜、红膜、铝膜3种反光膜对设施葡萄光合特性和叶片糖代谢的影响。结果显示:红膜和蓝膜处理的葡萄叶片的净光合速率均显著高于对照(不铺设反光膜);在果实发育前期,各处理的叶绿素含量和叶绿素b/a值均大于对照,而后期均低于对照;蓝膜和红膜处理叶片的蔗糖含量较高,而蓝膜处理叶片中的蔗糖合酶(SS)和蔗糖磷酸合酶(SPS)活性最高;各铺膜处理均比对照提高了葡萄果实鲜量和可溶性糖含量、降低可滴定酸含量,且蓝膜处理显著优于红膜和铝膜。研究表明,在设施栽培条件下,地面铺设蓝色反光膜可显著提高葡萄叶片的光合速率和叶片中碳水化合物的关键合成酶活性,并显著提高葡萄果实品质。

Abstract:Effects of different reflecting films,including red film(RF),blue film(BF) and aluminum film(AF),on photosynthetic characteristics and the enzyme activities related with sucrose metabolism in leaves were studied.The results showed that net photosynthesis
