Abstract

It has been suggested previously that Japanese larch (Larix kaempferi) exhibits characteristics of C_4 photosynthesis. To further evaluate this suggestion, stable carbon isotope ratios were determined for leaf and bark tissue of Larix gmelini, L. kaempferi, L. laricina, L. Iyallii, L. occidentalis, and L. sibirica. All δ^(13)C values were more negative than –22‰. Short-term labeling with ^(14)CO_2 showed that phosphoglyceric acid and other phosphorylated compounds were the first products of photosynthesis in L. sibirica. Both of these results strongly suggest that the initial fixation of atmospheric CO_2 in these six Larix species is accomplished solely via the C_3 photosynthetic pathway.
