Fresh-keeping Effects of 1-Methylcyclopropene on Cut-flowers of Gladiolus hybridus Hort.

The cut-flowers of Gladiolus hybridus Hort.,which were to be inserted in vase,were treated by 1-methylcyclopropene(1-MCP)under different concentrations.The result showed that compared with control treatment,1-MCP treament could improve the blossom rate of Gladiolus hybridus cut-flowers and increase theirs ornamental value,and reduce theirs withering degree.It also showed that the effect of 1-MCP treatment with φ=0.1 mL·L~(-1) was particularly the best.This treatment could extend the life of cut-flowers and improve theirs exterior quality,meantime could also retard the relative permeability of petals and leaves' plasma membrane,and have a certain effect on the content of petal protein and leaf chlorophyll.
