摘要
以瓶插寿命、花径大小变化、水分平衡值、鲜重变化率、生理生化指标,研究1-甲基环丙烯(1-MCP)与赤霉素不同浓度复合保鲜剂对非洲菊切花保鲜效果的影响。结果表明,蔗糖2.5%+1 MCP 10 mg·L^(-1)+赤霉素50 mg·L^(-1)的复合保鲜液比对照的切花瓶插寿命平均延长5.67 d,切花花径最大为12.40 cm;在瓶插过程中该处理切花的水分平衡值与鲜重变化率均大于其它处理;瓶插过程中超氧化物歧化酶(SOD)和过氧化物酶(POD)活性呈先上升后下降的趋势,复合保鲜液的切花酶活均高于同期对照组;丙二醛(MDA)含量呈上升趋势,复合保鲜液的切花MDA含量均低于对照组。综合结果表明,蔗糖2.5%+1 MCP 10 mg·L^(-1)+赤霉素50 mg·L^(-1)的复合保鲜液配方能够有效保持切花品质,延长切花瓶插寿命,为最佳保鲜液配方。
The effects of different concentrations of 1-methylcyclopropene(1 MCP)and gibberellin compound preservatives on the fresh keeping effect of cut Gerbera flower were studied by vase life,flower diameter,water balance value,fresh weight change rate,physiological and biochemical indexes.The results showed that the vase life of sucrose 2.5%+1 MCP 10 mg·L^(-1)+gibberellin 50 mg·L^(-1)was 5.67 days longer than that of the control,and the maximum diameter of cut flower was 12.40 cm.The water balance value and fresh weight change rate of cut flowers under this treatment were greater than those under other treatments.During the vase life,the activities of superoxide dismutase(SOD)and peroxidase(POD)exhibited an up and down trend,and the enzyme activities of the cut flower in the compound preservative solution were higher than those of the control group at the same period;the content of malondialdehyde(MDA)increased,and the MDA content in the compound preservative solution was significantly lower than that of the control group.Analysis showed that sucrose 2.5%+1 MCP 10 mg·L^(-1)+gibberellin 50 mg·L^(-1)could effectively maintain the quality of cut flowers and prolong the vase life of cut flowers,which was the best preservative formula.
