Abstract
In 14C fixation experiments, 3-phosphoglyceric acid was the first product of carbon assimilation in the light in Potamogeton pectinatus. The pattern of early 14C-labelled compounds was the same over a range of pH values of the medium from 3.5 to 8.1. Rates of 14C incorporation declined with increasing pH of the medium indicating that free CO2 is the major exogenous source of carbon for photosynthesis in Potamogeton pectinatus.This publication has 0 references indexed in Scilit:
