Translocation to and accumulation of phosphorus-32 in sclerotia of <i>Sclerotium rolfsii</i>

Abstract

Factors affecting translocation to and accumulation of phosphorus-32 in sclerotia of Sclerotium rolfsii were studied. Significantly more of the isotope was translocated and accumulated in the sclerotia when cultures were 6–7 days old rather than 10–11, when the direction of translocation was from old to young rather than from young to old portions of the cultures, and when the cultures were in about 400 ft-c of light rather than in darkness. In addition, the distance that the isotope could be translocated was also greatly influenced by these factors.
