| 摘 要： | 研究不同浓度(10、20和40 mg/L)茶多酚(Tea polyphenols,TP)对切花月季‘法国红’的瓶插寿命和相关抗氧化酶活性的影响,以探求一种新的切花保鲜剂组分,为切花保鲜提供理论依据。结果表明:与对照相比,TP浓度为10、20 mg/L时,切花月季瓶插寿命分别延长1.9 d和3.5 d,而浓度为40 mg/L时,反而缩短切花月季的瓶插寿命,并且浓度20 mg/L时,可提高瓶插前期切花花瓣内CAT、SOD和POD的活性,降低MDA含量。

| Abstract: | The research investigated the effects of tea polyphenols at 10,20 and 40 mg/L on vase life and antioxidase activity in red France cut roses,and identified the compound of fresh-keeping agents and theoretical foundation.Compared with the control flowers kept in distilled water,applications of TP(10 and 20 mg/L) prolonged respectively the vase life of cut rose for 1.9 d and 3.5 d,and the effect of 20 mg/L was apparent,but the opposite effect of 40 mg/L was also found.Furthermore,application of 20 mg/L increased the activities of CAT, SOD and POD of flower petals significantly and differentially,and decreased MDA content during the early vasing period. |
