摘要/Abstract

摘要： 研究了不同程度的遮荫(0, 50% , 75% ) 对一品红光合特性及生长的影响。结果表明, 一品红具有较高的光饱和点和较低的光补偿点, 是对光照强度适应能力较强的阳性植物, 但不同栽培品种对遮荫环境的适应性有较大差异。遮荫使一品红叶绿素含量增加, 叶色浓绿, 但降低光合速率, 减少叶片中可溶性糖和可溶性蛋白质含量, 抑制侧枝的生长, 使花头直径、红色苞叶面积减小, 苞叶花青素苷含量降低。

关键词: 一品红, 遮荫, 光合特性, 观赏品质

Abstract: The effects of shade degrees 100% , 50% and 25% of full sunlight on the growth and photosynthetic characteristics of poinsettia ‘Prestige’ and ‘Red Velvet’were examined. The results indicated that poinsettia was a sun plant with high light-saturation point and low light-compensation point. But the shade tolerance of different cultivars was different. Under shade conditions, the contents of chlorophyll increased and leaf color greener, but their net photosynthetic rates, the contents of soluble sugars and proteins in leavesdecreased and the growth of lateral shoots were inhibited, resulting in decreasing of flower diameters, red bract areas, contents of anthocyanidin in braces finally.
