Biological Diversity of Different Ecological Types of Halophytes

抄録

Morphogenesis and structure of vegetative and generative organs of 15 species of halophytes from Chenopodiaceae Vent. and Fabaceae Lindl. grown under natural desert habitats (Kyzylkum and Mirzachul) and cultivated on non-saline (Botanical Garden, Tashkent) soils were investigated. Influences of salts of different concentration and chemical composition on seed germination of 3 species of halophytes were determined. Mineral ions content in aboveground biomass (leaf, stem and root) of Suaeda altissima from saline (Mirzachul) and non-saline (Botanical Garden) soil were similar, with the exception of an insignificant difference in ion ratios. The adaptive features of flower organs for investigated halophytes on saline and non saline habitats are discussed.
