Abstract
Cu and Zn deficiencies were associated with a reduced rate of apparent photosynthesis in leaves of young tung trees. The amt. of reduction was less in the case of Zn deficiency than for Cu deficiency as they occurred in this expt. There was a highly significant reduction in CO2 assimilation even with normal-appearing leaves on deficient plants. The highest rates of photosynthesis in the fall occurred about the middle of Oct. and were associated with favorable weather conditions. As a rule the rates were higher in the mornings than in the afternoons.This publication has 1 reference indexed in Scilit:
