Analysys on Pollen and Seed Productivity and Effectivenes in Gentiana Lutea L.

ABSTRACT

A study on the viability of pollen grains and embryos in Gentiana lutea distributed in Bulgarian flora has been carried out. Degenerative processes predominantly of the mature pollen were observed. As a result of that, in the studied populations, the effective mature pollen grains in the anthers reduce in different amount. The used tetrazolium test shows that in the mature seeds the viability of embryos reduced progressively during the three consecutive years of the present study.
