Fig. 3From: Effects of red and blue light on leaf anatomy, CO2 assimilation and the photosynthetic electron transport capacity of sweet pepper (Capsicum annuum L.) seedlingsEffects of different light treatments: (a) white light; (b) monochromatic R light; (c) monochromatic B light; (d) mixed R and B light of 3:1 on leaf sectioning anatomy of sweet pepper seedlings at 28 day after treatment. Images of leaf sectioning anatomy are at the same magnification. The images were taken at 200 × magnification. EP, epidermis cell; PT, palisade mesophyll tissue; SPT, spongy mesophyll tissueBack to article page
