LED复合光质对洛阳红形态和生理特性的影响

Effects of LED Polychromatic Light on Morphological and Physiological Characteristics of ‘Luoyang Hong'

本试验以牡丹年宵花洛阳红品种为试材,研究了不同LED复合光质补光对其形态特征和生理特性的影响。结果表明:对牡丹生长最有利的复合光是红蓝绿复合光,对牡丹开花最有利的复合光是红蓝黄;对牡丹叶片色素积累最有利的复合光是红蓝黄绿紫;红蓝、红蓝黄、红蓝绿复合光最利于牡丹叶片可溶性糖、可溶性蛋白的积累。试验为改良牡丹年宵花的品质提供理论依据。

As the candidate national flower, tree peony has an important ornamental and medicinal value, Phalaenopsis tree peony couldn＇ t satisfy domestic demand recently. Thus, it was studied that the effect of LED polychromatic light on the morphological characteristics and physiological characteristics of potted Tree Peony ＇ Luoyanghong＇. The results show that the best polyehromatic light on the growth of potted peony is red-blue-green. The best polychromatic light on the blooming of potted peony is red-blue-yellow. The best polychromatic light on the peony leaf pigment accumulation of potted peony is red-blue-yellow-green-purple. Red-blue, red-blue-yellow, red-blue-green are better for the accumulation of soluble sugar, soluble protein for potted peony leaf. Test results provide theoretical basis for improving the ornamental and value of tree peony.
