Early Flowering in Cherry: Effects of Genotype, Environment, and Chemical Growth Retardants

In a series of tests with juvenile Prunus serotina, growth retarding chemicals (Alar, CCC, Ethrel), long-day greenhouse conditions and drought did not stimulate flowering. All seedlings from a low elevation source flowered in pots within two years from seed, regardless of chemical or environmental treatment; no high elevation seedlings flowered under similar conditions. Flowering observations in a three-year-old planting of black cherry confirmed this relationship between early flowering and altitudinal provenance. In a comparison test Prunus besseyi seedlings flowered prolifically after their first season's growth and P. virginiana after two seasons.
