The photosynthetic partitioning of 14C was studied in an ephemeroid plant Rheum maximoviczii Losinsk., which grows rapidly and forms vigorous shoots and underground organs during its short vegetative period. During the period of enhanced photosynthetic activity in the leaves, the proportion of the assimilated 14C in phosphoglyceric acid (PGA) and sugar phosphate esters decreased, while increasing in sucrose, where it amounted to up to 50% of the total radioactivity of water-ethanol extract. The proportion of 14C incorporated into PGA and fructose increased, while the proportion of 14C incorporated into sucrose drastically decreased at the lowering of photosynthetic activity. A great amount of storage carbohydrates are synthesized and accumulated in the underground organs of R. maximoviczii during a short-term period. Rapid utilization of this reserve can occur during plant regrowth in early spring.
