Description

The character of adaptive changes on the quantitative and qualitative indicators of the collection of tropical and subtropical plants is explored. Established that the adaptive response of tropical and subtropical plants related to their origin and ecological and biological characteristics that determine their growth, development, fenorytmotyp, anatomical and morphological and physiological and biochemical changes. It was determined that the proportion of species through adaptive changes implemented occurrence of forced rest. This type of change is associated with the origin of species and is inherent, mainly, from the West Indies, the Deans, the Siamese, Central, Brazilian, Cape, Mexican and South-Brazilian botanical and geographical provinces. Identified adaptive changes that are characterized by high amplitude variability of onset and duration of flowering phase related to the origin and form of plant growth. There is a tendency to increase the introductive capacity of plants in the row from trees to herbaceous perennials. The average index ? (mean square deviation from the beginning of flowering phase) in the studied herbaceous plants of the collection is 31.7; in the shrubs - 31.2, in trees and chimneys - 14.3. A complex evaluation of ecological-biological, morphological, anatomical, and physiological features of the genus Pittosporum Banks et Sol has been carried out. Adaptations of species in the conditions of industrial interiors are found in the reduction of annual growth, the number of newly formed leaves, the reduction of the size of leaf blades, the elongation of the interstitial, the growth of signs of xeromorphism. Structural changes of the leaf were revealed: increase of the thickness of the adaxial epidermis by 4% -32% in different species, reducing the thickness of the leaf blade by 2% -23.4%. The growth rate of the palisadicity (0.9% -20.8% before control) was revealed. Adaptation at the physiological and biochemical level was manifested in the change in the quantitative indices of the content of plastidic pigments and their correlation. Adaptive reactions also manifested in the change of the fractional composition of peroxidase in plant leaves of some species under different growing conditions. It has been established that such adaptive changes are determined by the origin of plants and their ecological and biological features.
