Title: Translocation of 14-C in ponderosa pine seedlings
Author: Ziemer, Robert R.
Source: Canadian Journal of Botany 49(1): 167-171.
Description: The movement of 14-C from the old needles to the roots, and later to the new needles, was measured in 2-year-old ponderosa pine seedlings. The seedlings were in one of three growth stages at the time of the feeding of 14-CO-2: 9 days before spring bud break with no root activity; 7 days before spring bud break with high root activity; and 7 days after spring bud break with moderate root activity. The form of the curves of count rate plotted against time are similar for a given plant part
Keywords: PSW4351, ponderosa pine seedlings, translocation of photosynthate
