Reproductive strategy of representatives of the genus Sparganium L.: brief overview of the problem

The article presents the results of the study of seed productivity and the characteristics of fruit buoyancy in representatives of the genus Sparganium L. New data on the duration of preservation of the germination capacity of bur-reed fruits under conditions of humid cold stratification are presented; the maximum values of the laboratory germination index of fruits of different Sparganium species under humid cold stratification are shown. A brief description of the ontogenesis of an individual of seed origin is given. It is established that the reproductive strategy of bur-reed includes the implementation of two developmental pathways – a combination of sexual and asexual reproduction or only asexual reproduction. In this case, the second type of reproductive strategy prevails.
