Reproductive effort in plants

Markov M. V.; Pleshchinskaya E. N.

The application of reproductive effort determined by the weight of reproductive structure to the plant weight ratio for estimating life strategies of various animal and perennial plant species and ordinating these species in a continuum of strategies is considered. It was shown, Plantago and Androsace taken as examples, that annual plants, unlike perennial ones, are characterized by a high and stable reproductive effort slightly varying even at considerable changes in plant development.
