Differential Growth Rate of Young Progeny of Individual Slash Pine Trees
If it can be shown that progeny of individual trees vary in vigor, then source of seed becomes an important factor in racial variation studies, nursery selection studies and in investigations of the effect of seed size on seedling vigor. Observation at the Ida Cason Callaway Tree Improvement Project near Chipley, Georgia, of slash pine progenies through their 5th year indicate that such differences in vigor actually exist.
