摘要
以菊花鲜切花为试材,以蔗糖、CaCl2、水杨酸、柠檬酸、明矾不同组合液为保鲜剂,研究了不同试剂组合对菊花切花保鲜效果的影响。结果表明:加入不同组合试剂均可不同程度地推迟菊花最大花径开放时间,改善切花体内水分平衡,保持切花鲜重,显著延长切花瓶插寿命。其中试剂组合100mg/L明矾+50mg/L柠檬酸+75mg/L水杨酸+2g/L CaCl2+4%蔗糖和100mg/L明矾+50mg/L柠檬酸+2g/L CaCl2+4%蔗糖不仅对增加切花鲜重效果显著,又明显延缓了水分平衡负值的出现,能较好地维持切花鲜重,明显延长菊花切花寿命。无蔗糖的处理100mg/L明矾+50mg/L柠檬酸+75mg/L水杨酸+2g/L CaCl2虽然含有无机盐和有机酸,但缺少能源物质,保鲜效果明显下降。
The effect of different combinations of sucrose,CaCl2,salicylic acid,citric acid and alum on the fresh-keeping of cut chrysanthemum flower were studied with distilled water treatment as control.The results showed that all treatments could delay the flowering time of chrysanthemum reaching to the maximum corolla diameter,improved the water balance,kept fresh weight in different extent,and extend the vase life of cut flowers significantly.The combinations 100 mg/L alum＋50 mg/L citric acid＋75 mg/L salicylic acid＋2 g/L CaCl2＋4% sucrose and 100 mg/L alum＋50 mg/L citric acid＋2 g/L CaCl2＋4% sucrose not only increased the cut flower fresh weight obviously,and delayed the negative value appearance of the moisture balance significantly.Meanwhile,the both treatments maintained the fresh weight better,and prolonged obviously the blooming time of chrysanthemum fresh-cut flower.But it decreased the preservation effect obviously with the treatment 100 mg/L alum＋50 mg/L citric acid＋75 mg/L salicylic acid＋2 g/L CaCl2 which without sucrose,although it contained inorganic salt and organic acid,it lacked energy resources.
