Studying of pollen storage questions in connection of interspecific hybridization in decorative representatives of Scrophulariaceae Juss.

The purpose of the research was to study the storage of pollen of some species of Scrophulariaceae Juss, in connection with interspecies hybridization. The tasks were to study the fertility and sterility of pollen; timing and duration of storage of pollen; storage methods that prolong the viability of pollen in studied species. The objects of study were 4 species of the family Scrophulariaceae Juss.: Asarina scandens L. = (Maurandia semperflorens, Antirrhinum majus L., Mimulus xhybridus Hort., Penstemon x hybridus Groenl. et Ruempl. The study was performed at Russian State Agrarian University - MAA named after K.A. Timiryazev. The methods of the study: accounting and observations, statistical data processing using variance analysis. The research techniques were acetocarmine pollen staining; counting fertile and sterile grains under a microscope. A great influence on the conservation of fertile pollen grains was made by the factor “Plant species, genotype” - 39 %, share interaction of factors “type and storage conditions” - 28 %...
