Abstract
The distribution of 14C in various tissues of fiber flax was assayed 1, 17, and 21 days after 30-min assimilation of 14CO2 by the whole rapidly growing plant. Polymeric photosynthetic products were largely hydrolyzed in the 14C-donor part of the shoot, and the hydrolysates were transported upward. The content of 14C in pigments and lipids of the donor leaves (that absorbed 14CO2) was significantly higher than that in the 14C-acceptor leaves. Additional nitrogen nutrition decreased the labeled sucrose-to-hexose ratio and inhibited transport of the assimilates from both 14C-donor and acceptor leaves. 14C transported to the shoot tip was largely used for the synthesis of poorly soluble proteins (extractable with alkali and Triton X-100) in the acceptor tissues. In the donor part of the shoot, particularly in the bast, cellulose was mainly synthesized from the “new” assimilates.
