Solonenko V. Trifolium ambiguum Bieb. (Fabaceae): biomorphological and ecological peculiarities, introduction in forest-steppe of Ukraine

In the dissertation the results of biological and morphological peculiarities of the steppe ecotype plants of T. ambiguum and proposals of their introduction in forest-steppe regions of Ukraine are presented. It has been stated that T. ambiguum is regarded as a caudex-rhizome policarpic with semirosetteous sympodial shoots. The main regularities of ontomorphogenesis since germinating till reproductive stage were researched. Peculiarities of caudex and rhizomes development, partial plants and additional roots have been studied.Types of additional roots are described, peculiarities of symbiotic activity and bulbella formation of T. ambiguum plants have been estimated. Morphological and biological peculiarities on blossoming stages have been studied; dependences of a seed productivity and inflorescence differentiation in generative organs have been established. Dynamics and development stages of T. ambiguum in culture were studied.
