1-MCP处理对金百合切花保鲜效应的研究

Effects of 1-MCP Treatment on Fresh-keeping of Lilium ‘Prato’ Cut Flowers

摘要:

以金百合“普瑞头(Prato)”为试材，研究1-MCP对切花瓶插寿命及相关生理代谢的影响。结果表明：金百合“普瑞头(Prato)”为呼吸跃变型切花。30 nl L-1的1-MCP能显著延长切花瓶插寿命2.15 d、盛开天数增加0.43 d，使其花径增大1.68倍(P＜0.01)；有效延缓了水分代谢的失调与呼吸峰的出现时间；明显降低了呼吸强度与细胞膜透性，为供试百合品种最适应用浓度。

Abstract:

The effects of 1-methylcyclopropene (1-MCP) treatments on vase life and physiological changes of cut flowers of Lilium ‘Prato’ were studied. The results indicated that the respiratory pattern of ‘Prato’ lilybelonged to climacteric type. Treatmented with 30 nl L-1 1-MCP, the vase life of lily cut flower prolonged obviously by 2.15 days, full blooming increased by 0.43 days, and the flower diameter enlarged by 1.68 times (P＜0.01). 1-MCP could effectively delay the appearance of respiratory peak and moisture decompensation in cut flowers, markedly decreased respiratory rate and relative cell membrane permeability. It was suggested that 30 nl L-1 1-MCP was suitable for fresh-keeping of ‘Prato’ lily.
