Gibberellic acid (GA3) causes cell elongation in cotton suspension cultures derived from cotton ovule callus tissue of both auxin-dependent and-independent lines. Cell elongation was more pronounced in auxin-dependent cultures. Cells were cultured for a period of 14 days but differences in cell lengths could be detected after 6 days in culture. Cell elongation took place in cultures in which GA3was present throughout the culture period or only for the first 3 days. Auxins and cytokinin alone or in the presence of GA3did not promote cotton cell elongation above the value for the treatment with GA3alone.
