title: Initial and post-cryogenic assessment of viability of russian plum cultivars pollen (<i>Prunus rossica</i> Erem.) in the conditions of the North-West of Russia
abstract: The viability of pollen of 5 collectible varieties of Russian plum of the Pushkinskiye and Pavlovskiye VIR Laboratories SPB before and after cryopreservation was studied. It was found that a significant factor for the level of pollen viability is “variety” (p=0.07), the factors “cryopreservation” (p=0.457), “year” (p=0.221), as well as the interaction of the factors “variety× cryopreservation” (p=0.172), were not significant at the p&lt;0.05 level of significance. For long-term storage of Russia
