植物的生長全賴光合作用提供能量及資源。在這層面上,所選用的光源亦是一大學問。271Please respect copyright.PENANAOXNnuYWf6s

(圖2)葉綠素(Chlorophyll)為植物吸收光線的重要位置。271Please respect copyright.PENANApL0EaE7fWr
利用化學物分離葉綠素的話,共可分為葉綠素a及葉綠素b兩大部份。271Please respect copyright.PENANAPlKZ8R6UU9
271Please respect copyright.PENANArXVaaOfhgh
271Please respect copyright.PENANArQu4DkOige
葉綠素a主要吸收紅光,而葉綠素b則主要吸收藍光。271Please respect copyright.PENANArLvEo6Jl7u
271Please respect copyright.PENANAS7UX1C0Feb
綠光並沒有有效地被葉綠素吸收的關係,因此葉綠素在我們的眼中呈為綠色。271Please respect copyright.PENANAx3an96EK8d

(圖3)近來有研究發現,配合日照再加上紫外線燈(UVA)的方式種植,生菜的葉綠素、蛋白質、維他命C及糖粉對比單獨日照方式種植更之為高,而硝酸鹽的成份則有所降低。271Please respect copyright.PENANAgtOQ4n3PV1

這有可能是紫外線對植物的新陳代謝產生變化所致,還需要進一步的研究才能證實。271Please respect copyright.PENANA88LWe1MzIS
