Orchid Erythrodes nobilis is ranked among terestrical orchids, which grows in shady undergrowth of Brazil tropical rainforest. This species has adapted to very strong shading. This thesis is focused on adaptations on shading of orchid Erythrodes nobilis, especially anatomical adaptation, chlorophyl adaptations and growth analysis. The typical feature of leaves structure of an orchid Erythrodes nobilis are especially lens-like cells in the skin and two-layers wide palisade parenchyma with high content of chlorophyl. The plant has responded to darkening with enhancement of leaf size, chlorophyl content and even the content of b-chlorophyl in adult leaves and creation of new leaves with enormous specific leaf size. |
