Intraspecific Variation Among Twenty-Five Populations of Black Cherry, Prunus Serotina, Studied Near Washington, D.C.

Prunus serotina from 25 different seed sources, studied in Maryland, near Washington, D.C., varied in growth rate, survival, date of setting l eaves and flowers, and branching habits. Six-year heights ranged from 3.6 (Wise County, Virginia) to 9.6 feet (Alachua County, Florida). Five-year survival varied from 44% or less (Florida and Georgia populations) to over 85% (five populations from the northern range). The earliness of setting leaves and flowers was inversely correlated with the elevation; also, the earliness of flower-set was positively correlated with the annual temperature of the provenance. A population from Monroe County in Tennessee had distinctly straighter stems and smaller branches than most other populations studied.
