MICROSPOROGENESIS IN THE Pyrus, Malus, Cerasus, Microcerasus VARIETIES AND THEIR HYBRIDS
L.F. Yandovka1, R.V. Papikhin2
The features of microsporogenesis were studied in Pyrus communis, Malus domestica, Cerasus vulgaris, Microcerasus tomentosa, Cerasus avium species and their interspecific and intergeneric hybrids. The typical and non-typical abnormalities in microsporogenesis were described. The typical — were found in all studied plants, the non-typical — in hybrids, as rule. The non-typical abnormalities caused the low fertility of pollen grains.
Keywords: microsporogenesis, pollen fertility and viability, Pyrus communis, Malus domestica, Cerasus vulgaris, Microcerasus tomentosa, Cerasus avium.
