Seed productivity of Prunus sargentii rehder as an indicator of the success of introduction

The results of studies of the fruiting characteristics of Prunus sargentii Rehder in the conditions of the Moscow region are presented. It has been established that most plants of the introduced population, which are in a generative state, consistently bloom and bear fruit. The fruit ripening period averages 35-40 days. Despite the different flowering periods of individual trees, the ripening of fruits on them occurs simultaneously. The phenological phases of fruit formation have been studied, an analysis of morphometric parameters and variability of fruit characteristics by weight, length and width are presented. Indicators of seed productivity have been established: potential and real seed productivity, the percentage of flowering, the coefficient of seedification. The stable flowering and fruiting of P. sargentii in the conditions of the Moscow region indicates the prospects of the species for its further widespread use in landscaping.
