摘要
本试验对芍药品种‘大富贵’采前分别用200、400、600μL/L的1-甲基环丙烯(1-MCP)进行喷施处理,测定其切花花径及花枝吸水量、失水量。结果显示,采前经1-MCP处理的切花花径、花径增大率均小于对照,且1-MCP浓度越大,花径越小。不同处理芍药切花吸水量均呈前期快速下降,后期逐渐平稳状态;失水量均呈先增加后降低趋势;水分平衡值呈先下降后上升趋势。本试验中1-MCP的最佳浓度为200μL/L,此浓度下可保持切花质量,延长观赏期。
Herbaceous peony ‘Dafugui’ was treated with 200, 400, 600 μL/L 1-methylcyclopene(1-MCP) before harvest, and the flower diameter and water absorption and water loss of flowering shoots were measured. The results showed that the diameter and diameter increase rate of cut flower treated with 1-MCP before harvest were less than those of the control, and the larger the concentration of 1-MCP was, the smaller the flower diameter was. The water absorption of cut flowers under different treatments all showed a rapid decline at the early stage and gradually stabilized at the later stage. The water loss showed a trend of first increase and then decrease. The water balance value first decreased and then increased. In this experiment, the optimal concentration of 1-MCP was 200 μL/L, which could maintain the quality of cut flowers and prolong the ornamental period.
