Modificarea activităţii microgameţilor la descendenţii tomatelor reinfectate cu virusuri [Articol]

Abstract

The paper presents the results of studies of the effect of high temperature and water stress on the variability of the male gametophyte of tomato offspring obtained from plants infected with viruses. Specific variability of such parameters as pollen-forming ability, pollen viability and pollen tube sizes was established. The obtained results by processing of multivariate dispersion analysis showed that the variability of these traits is largely controlled by the genotype and stress factors. At the haploid level, differences in genotype resistance to temperature and water deficiency were revealed. Genotypes characterized by a high level of microgamete resistance were identified for further practical use.
