Abstract:

Slash pine tissue cultures consumed from 0.1 to 5.6 l O2mg dry wt/hr. Actively growing areas of the callus, comprised of cells with large nuclei and small vacuoles, had high respiration rates. Areas containing brown pigment had low rates and were composed of cells with large vacuoles containing a tannin-like substance. Six distinct areas, based on callus coloration, were compared physiologically, histologically, and cytologically. Forest Sci. 18:298-307.

Keywords: Pinus elliottii; callus culture; respiration; tannin; ultrastructure
