A study has been made of the kinetics of hormone-induced H(+) excretion from peeled Avena coleoptile sections using a new, simple technique involving direct application of the pH electrode to the surface of the section. Hormone-induced H(+) excretion begins after lags and occurs at rates which are consistent with a role of H(+) in regulating cell elongation. With fusicoccin, H(+) excretion begins within the 1st minute, and an external pH of 5 (optimal for wall loosening) is reached in 5 to 8… CONTINUE READING
