Effects of Ethanol and 1-Methylcyclopropene on the Vase Life of Cut Narcissus tazetta van chinensis Roem.

摘要

In this study, effects of ethanol and 1-methylcyclopropene (1-MCP) were investigated on the senescence of cut Narcissus tazetta var. chinensis Roem. toprolongthe vase life safely and cost-effectively. Ethylene treatment at 500 mul L~(-1) for 24 h significantly shortened the vase life of both florets and spikes, showing that it is ethylene sensitive. Gaseous 1-MCP treatment at 1 mul L~(-1) was effective in extending the vase life of florets but not the spikes. Ethanol treatment with 0.1% holding solution was significantly effective in delaying the senescence of the florets and extend the vase life of both the florets and spikes of the cut flowers.
