| 摘 要： | 以切花月季‘卡罗拉’ Rosa hybrida ‘Corolla’为材料，通过在瓶插液中添加褪黑素（melatonin，N-乙酰-5-甲氧基色胺），研究了外源褪黑素对切花月季‘卡罗拉’保鲜效应的影响。结果表明:与对照瓶插液（蒸馏水）相比，20 μmol·L-1褪黑素+基础瓶插液（30 g·kg-1蔗糖+250 mg·L-1 8-羟基喹啉+200 mg·L-1柠檬酸）复合瓶插液显著提高切花月季‘卡罗拉’花径张开度和切花水分平衡值（P < 0.05），减缓切花鲜质量变化率下降速度，且抑制了瓶插液中细菌的增长，对切花月季‘卡罗拉’保鲜效应最佳，其次是20 μmol·L-1的褪黑素瓶插液和基础瓶插液。

| Abstract: | To determine the influence of melatonin (MT, N-acetyl-5-methoxytryptamine) in keeping roses fresh, cut rose flowers (Rosa hybrida 'Corolla') were selected as experimental materials with MT added to the preservation solution, and the treatments were as following:control (ck, distilled water), 20 μmol·L-1 MT solution, base fluid (30 g·kg-1 sucrose + 250 mg·L-1 8-hydroxyquinoline + 200 mg·L-1 citric acid), 20 μmol·L-1 MT + base fluid. Results showed that compared to ck, 20 μmol·L-1 MT + base fluid preservation solution significantly increased the diameter of the blossom and the water balance value of cut flowers as it slowed decline in the change rate of its fresh weight (P < 0.05). Moreover, addition of MT inhibited bacterial growth in the base fluids. Thus, the liquid mixture of base fluid with 20 μmol·L-1 MT preservation solution, was the most effective preservative solution in this study. |
