Microgeographic adaptation to temperature in pitch pine progenies

Localized variation in cold tolerance of pitch pine (Pinus rigida Mill.) seedlings from an area including a large frost pocket was examined over an autumn, winter and spring. Sizable differences in cold tolerance were discovered among population and individual-tree progeny samples, as measured by pa...
