Variability of morphometric characteristics of Galega orientalis Lam. In some populations of natural and secondary ranges

It is shown that, in the invasion process, the G. orientalis phenotype has changed and differs from the natural one. The invasion phenotype is more “vigorous”: the total biomass of the top plant organs, the length of inflorescences, the number of flowers, and also seed productivity are increasing. A tendency toward augmentation of some morphometric features under the increase in duration of the naturalization process is noted. The study data reveal an increase in competitive ability of G. orientalis in the secondary range and support the EICA hypothesis (Evolution of Increased Competitive Ability).
