| Research Abstract |
Leaves of tree plants contain some specific pigments such as α-carotene and lutein epoxide derivatives that are not involved in herbaceous plants. The alternation in growth condition caused the vibrations of contents and components of the specific pigments in leaves. The biochemical responses to environmental stresses in tree plants were detected as co-operative functions and lutein epoxide cycle. We showed that the energy control through pigments alternations operated as tree specific environmental adaptation.
