Sections of leaves from plants cultivated in the greenhouse showed the layer of palisade cells well-organized and some of these cells underwent periclinal division; well-developed cuticle; presence of idioblasts containing crystals (Figure 3).
Leaves from the plants grown at 10/20degC not only had more spongy mesophyll tissue, but also longer palisade cells, compared to the leaves from the 20/30degC treatment.
