Effect of 1-methylcyclopropene on vase life on new cut foliage species first experimental results.  Cut foliage is more and more required by the market, since it is an element of capital importance in flower compositions, as a consequence of its considerable aesthetic value.Considering the knowledge acquired up to day in the experimentation o­n traditional cut foliage o­n post-harvest senescence physiology, specific investigations o­n new foliage species are still necessary, because their cultivation is increasing.

Therefore the following experimentation was carried out: Aster novaeangliae, Bergenia crassifolia, Callicarpa bodinier cv Profusion, Cornus alba cv Eleganitissima, Cotinus coggygria cv Royal purple, Hosta fortunei, Hosta halcyon, Photinia x fraserii cv Red Robin, Physocarpus opulifolius cv Diabolo, Phytolacca americana, Symphoricarpos cv White Pearl.

The parameters considered were vase life and fresh weight trend during the conservation period.The preserving solution was made of 25 mg L-1 AgNo3 + 50 mg L-1 Al2(SO4)3 + 25 gL-1 sucrose and was compared with deionized water.Also the action of 1-methycyclopropene was evaluated (during 12 hours treatment).So the treatments the foliage species received were: 25 mg L-1 AgNO3 + 50 mg L-1 Al2(SO4)3 + 25 gL-1 sucrose; AgNO3 + 50 mg L-1 Al2(SO4)3 + 25 gL-1 sucrose + MCP; Deionized water; Deionized water + MCP.

An amount of 35 mg of EthylBlocâ was used and the container in which the foliage was put had a volume of 50 L.The results obtained highlighted the worth of using 1-MCP with the following species: Bergenia crassifoia as fresh weight trend and vase life; Cornus ala cv Elegantissima as weight trend and vase life; Cotinus coggygri cv Royal purple as weight trend; Hosta fortunei as vase life; Hosta halcion as vase life; Photinia x fraserii as fresh weight trend; Physocarpus opulifolius cv Kiabolo as fresh weight trend; Phytolacca americana as vase life and fresh weight trend.
