Abstract
When applied to a part of stem or basal part of stem and root system, 1 ppm ethylene induced lysigenous aerenchyma development in the stem cortex of Helianthus annuus, Lycopersicon esculentum, and Phaseolus vulgaris. Local application of ethylene to a part of stem significantly increased the activity of cellulase in that part of stem in the above three species. Pretreatment of a part of stem with 100 ppm AgNO3 counteracted the effects of ethylene which was subsequently applied to the part of stem, completely suppressing aerenchyma development and highly significantly reducing cellulase activity in Helianthus annuus. These results support the earlier proposal that the deficiency of oxygen in waterlogged plants triggers the anaerobic stimulation of ethylene production, which in turn increases the cellulase activity leading to aerenchyma development.
