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,H0·01μmol·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。

摘  要:
Effects of exogenous carbon monoxide (CO) donor (Hematin) at 0.001, 0.01 and 0.1 μmol· L~ -1 on vase life and antioxidative metabolism in cut rose ‘Movie Star’flower were investigated. Compared with the control flowers kept in distilled water, application of CO donor hematin (0.001-0.01 μmol·L~ -1 ) resulted in the prolonged vase life of cut rose in a dose-dependent manner. Between these treatments, the effect of 0.01 μmol·L~ -1 hematin (H 0.01) was the most effective in extending the vase life. However, the opposite effect of 0.1 μmol·L~ -1 hematin (H 0.1) was also found. Furthermore, application 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.
