| Abstract:
About 160 different crosses of various species, cultivars and hybrids of Prunus L. were studied via fluorescence microscopy. Study of pollen growth in the pistils and of the fertilization process allowed conclusions on self- and cross compatibility of various cultivars and hybrids to be made. About 40 forms, including new cultivars of P. cerasifera ‘Vitsba’, ‘Vetraz’ and ‘Asaloda’ and P. avium ‘Gastsinets’ were used for female gametophyte investigations. The investigations on pollination process and on ovule viability permited to establish a cause of premature fruit dropping. The results let us propose good pollinators and select cultivars and hybrids with high percent of viable ovules. | |
