Abstract

Increased concentrations of CO2 with the accompanying high bicarbonate level in the culture medium have been reported to have a depressing effect in certain plant species on growth (34), respiration (23, 33), oxidative phosphorylation (9), mineral nutrient absorption (17), certain enzymatic reactions (4, 22, 27), accumulation of organic and amino acids (11), and protein synthesis (16). Since accumulation of organic acids occurs in lime-induced chlorotic tissue together with a depression in the respiration of plant tissue, an effect on the energy transfer mechanism of such plants is suspected. Inhibition of electron transfer from the substrate level could result in decreased oxidative phosphorylation.
