不同光质对三色堇的生长发育的影响较大,本文研究了红、黄、蓝、紫、绿、白六种光质对其花期、叶面积、株高、冠幅等生理特征的影响。结果表明:红光能够诱使三色堇提早开花,开花周期缩短,蓝光能够诱使推迟开花,开花周期延长。红光有助于三色堇有机物的积累,绿光抑制有机物的积累。绿光促进株高生长,紫光抑制株高生长。三色堇在蓝、紫、绿光条件下总叶面积大,红光最小。 The effects of different light qualities on the growth and development of Pansy were greater. The effects of six light qualities of red, yellow, blue, purple, green and white on the physiological characteristics of florescence, leaf area, plant height and crown width were studied . The results showed that: the red light can induce early flowering pansy, flowering period shortened, blue light can induce delayed flowering, flowering period prolonged. Red light contributes to the accumulation of Pansy organic matter, and the green light suppresses the accumulation of organic matter. Green light promotes plant height growth and purple light inhibits plant height growth. Pansy in the blue, purple, green under the conditions of the total leaf area, the smallest red.
