Chorological-ecological model of the spread of Puccinellia distans (Poaceae) in Central Europe.

摘要

A chorological-ecological model of the spread of Puccinellia distans (L.) Parl. in Central Europe is described. The reasons for its spread and basic features of the mechanism of this process are discussed. It is suggested that the success of P. distans in the colonization of new habitats and areas is connected with the presence of many features facilitating adaptation. These features occur at all stages of the population development, from seed dispersal to germination and completion of the life cycle.
