Abstract

A number of workers have noted that treatment with CO2, or with acid buffers at approximately the pH of CO2-saturated water, can bring about a remarkable promotion of extension growth or water uptake (see Evans, Ray and Reinhold 1971 for refs.). Some years ago Zvi Glinka and I (1966) were rather awed to observe that only extremely brief exposure was necessary to obtain the effect — promotion of water uptake by sunflower hypocotyl segments was easily observable after 10 sees, treatment with CO2. More recently Michael Evans, Peter Ray and I (1971) made a detailed study of CO2-induced growth and found, among other things, that within 1 min of the start of treatment the rate of elongation of coleoptiles rises 8–16 fold.
