摘要: 研究了不同浓度(0.001、0.01和0.1μmol·L - 1 ) 的外源一氧化碳(CO) 供体高铁血红素(Hematin, H) 对切花月季‘影星’的瓶插寿命和抗氧化代谢的影响。结果表明, 与对照相比, CO供体在0.001~0.01μmol·L - 1范围内, 随使用浓度的提高延长了切花月季的瓶插寿命, 其中0.01μmol·L - 1处理效果最明显, 而0.1μmol·L - 1的处理反而缩短切花月季的瓶插寿命。进一步研究发现, H 0.01μmol·L - 1处理还不同程度地上调前期过氧化物酶、过氧化氢酶和超氧化物歧化酶活性, 显著降低MDA含量。

Abstract: Effects of exogenous carbon monoxide ( CO ) donor (Hematin) at 0.001, 0.01 and 0.1μmol·L - 1 on vase life and antioxidative metabolism in cut rose‘Movie Star’flowerwere investigated. Compared with the control flowers kept in distilled water, application of CO donor hematin (0.001 - 0.01μmol·L - 1 ) resulted in the prolonged vase life of cut rose in a dose-dependent manner. Between these treatments,the effect of 0.01μmol·L - 1 hematin (H 0.01) was the most effective in extending the vase life. However, the opposite effect of 0.1μmol·L - 1 hematin (H 0.1) was also found. Furthermore, app lication of H 0.01 apparently and differentially up-regulated the activities of peroxidase, catalase and superoxide dismutase, resulting in the apparent decrease of MDA content during the early holding period.
