摘要/Abstract

摘要： 以非洲菊( Gerbera jamesonii) 切花为材料, 研究衰老过程中活性氧的变化, 比较外源乙烯、外源活性氧对衰老的效应, 寻找缓解衰老的措施。结果表明, 非洲菊切花衰老过程中活性氧代谢活跃, 对外源活性氧的敏感性大于外源乙烯, 采用以抑制活性氧为主要成分的瓶插液能有效缓解切花衰老。

Abstract: The metabolism of active oxygen was investigated during senescence of cut Gerbera jamesonii and effects of exogenous ethylene and exogenous active oxygen species on the cut flowers were studied in terms of modern plant senescence theory and by means of modern detected method. The technical measures that delayed the senescence of cut gerbera were found and the corresponding mechanisms were discussed in this paper. The results showed that the level of active oxgen metabolism during the senescence of cut gerbera flower was high. Gerbera was much more sensitive to the kinds of exogenous active oxygen than that to exogenous ethylene. The suitable concentration of active oxygen scavengers could retard the senescence of cut gerbera.

Key words: Gerbera, Cut flower, Active oxygen metabolism, Senescence
