The effects of IAA and ethylene have been compared on the development of epidermal cells in intact shoots of etiolated pea plants. In the expanding sub-apical region ethylene has little effect on cell volume over 24 h but between 12 and 24 h rapid increases occur in cell wall thickening, part of which is due to the deposition of longitudinally orientated(More)
Both ethylene and IAA induce swelling in the sub-apical region of etiolated pea plants. The modified cells of these two types of swellings differ both morphologically and in their enzyme composition. In ethylene the cell walls become thickened within 24 h and the level of peroxidase is enhanced; ethylene does not affect cellulase levels. IAA induced(More)
