摘　　要：本研究设置0.0005、0.0050和0.0500μmol/L 3个不同浓度的氯化血红素(Hemin),探究其对不同品种康乃馨的鲜切花保鲜的影响。试验结果表明,不同浓度Hemin处理均能显著提高3个康乃馨品种的瓶插寿命和观赏价值,其中以0.0050μmol/L的Hemin处理效果最佳。Hemin处理通过调节体内生化机理延缓切花康乃馨的衰老,能明显提高康乃馨的瓶插寿命、最大花径,保持花枝较高的水分平衡值,从而提高鲜切花的应用价值。This paper reports the effects of Hemin at 0.0005,0.0050 and 0.0500μmol/L on vase life in different cut carnation(Dianthus caryophyllus L.)flower were investigated.Results showed that treatment with the Hemin significantly increased carnation vase life of carnation cut flowers and ornamental value,of which 0.0050μmol/L of Hemin best effect.Hemin treatment delayed the senescence of cut flower carnation by regulating the biochemical mechanism in vivo,can significantly improve the vase life and maximum flower diameter of carnation,and maintain a high water balance value of flower branches,thereby improving the application value of fresh cut flowers.
