Gibberellin and the Growth of Plant Tissue Cultures

Abstract

TWO recent publications report the effects of gibberellic acid on the growth of excised plant tissues. Netien1, working with isolates from the tuber parenchyma of Helianthus tuberosus, found a slight increase in growth at 1 p.p.m. in the absence of indolylacetic acid and a decrease at higher levels. In the presence of the auxin all levels of gibberellic acid were quite inhibitory. Schroeder and Spector2 used explants from the mesocarp of mature citron (Citrus medica). They found gibberellic acid, in the absence of indolylacetic acid, caused an increase in weight at 5 p.p.m. In the presence of indolylacetic acid all levels tested resulted in increases in weight.
