Abstract

1-Methylcyclopropene (1-MCP) applied alone did not influence significantly the chlorophyll and carotenoid content of the older leaves of Arabidopsis thaliana (L.) Heynh., but retarded the senescence of the younger ones (6th and 7th leaf nodes). However, 1-MCP effectively blocks the ethylene induced senescence of excised rosette leaves. The preliminary application of 1-MCP (3 h in advance to the treatment by Ethrel) almost totally eliminated the ethylene action. Similar trend was also observed after simultaneous application of Ethrel and 1-MCP, and the effects of both treatments on the chlorophyll and carotenoid destruction are comparable.
