Anatomic Adaptive Strategies of some Cormophytes with Individuals Growing in Light and Shade Conditions
AbstractThe adaptive structural and functional strategies enable plants to survive in variable biotopes. The intensity of some parameters of abiotic factors can be estimated from the environment on the basis of anatomic studies. In this research paper there are histo-anatomical studies of the leaf blades and stems of 10 angiosperm species which have populations growing in both open and shaded places from mountainous biotopes in the Ciuc-Basin¸ with the application of methods for making microscopical preparations. The qualitative evaluation of the histo-anatomical properties was combined with determination of stomata density and biometric data. Up to the present, there have been no histo-anatomical studies in plants distributed in these areas. The studied species possess histological structures adapted to utilizing more efficiently the light energy and humidity accessible to plants in their habitats. The structural adaptations to illumination conditions of the studied species can be distinguished in the structure, types and development rate of the assimilatory and mechanic tissues.
