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。721Please respect copyright.ＰＥＮＡＮＡSRlEeTwLzw

（圖2）葉綠素(Chlorophyll)為植物吸收光線的重要位置。721Please respect copyright.ＰＥＮＡＮＡDv9waLz0i7
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。721Please respect copyright.ＰＥＮＡＮＡhnOnxn1j5r

葉綠素a主要吸收紅光，而葉綠素b則主要吸收藍光。721Please respect copyright.ＰＥＮＡＮＡ6vJBiO0L3C

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。721Please respect copyright.ＰＥＮＡＮＡDfeQENZf2D

（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。721Please respect copyright.ＰＥＮＡＮＡAtOcK09NSm

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。721Please respect copyright.ＰＥＮＡＮＡsabQK17su6
