The difference of the respiratory metabolism was investigated and compared between two species of tropical cut flowers(phalaenopsis amabilis and gerbera jamesonii florijin)during senescence.Effects of exogenous ethylene,exogenous active oxygen and water stress treatment on respiration of cut flowers were studied.Technical measures to delay cut flowers senescence were sought and the corresponding mechanisms were discussed in this paper.The results showed that the respiratory rate was lower in Phalaenopsis than in Gerbera.Respiratory pathway in phalaenopsis proceeded predominantly via EMP and cyanide resistant respiration while predominantly via HMP in Gerbera.Phalaenopsis was much more sensitive to exogenous ethylene than to exogenous active oxygen.On the contrary,Gerbera was less sensitive.Ethylene inhibitor of suitable concentration could retard Phalaenopsis senescence,and active oxygen scavengers of suitable concentration could retard Gerbera senescence.

以蝴蝶兰(phalaenopsisamabilis)与florijn非洲菊(gerberajamesonii)切花花瓣为材料,研究比较2种切花衰老过程中呼吸的差异,以及外源乙烯、活性氧、水分胁迫对2种切花呼吸的效应,寻找缓解2种切花衰老的技术措施,并讨论其相应的机理。实验结果表明,蝴蝶兰呼吸速率低于非洲菊,且蝴蝶兰以糖酵解途径(EMP)、抗氰氧化酶(AP)为主,而非洲菊以磷酸戊糖途径(HMP)为主;蝴蝶兰对外源乙烯的效应大于对外源活性氧的效应,而非洲菊却相反。蝴蝶兰对外源乙烯敏感性大大超过非洲菊。适当浓度乙烯抑制剂能降低呼吸速率,延缓蝴蝶兰切花衰老,而适当浓度活性氧清除剂能缓解对呼吸的抑制,延缓非洲菊衰老,延长瓶插寿命。对2种切花进行干旱胁迫18h,可加速切花衰老,瓶插寿命相应缩短,但胁迫前用0.01%TritonX-100预处理1h,能有效缓解水分胁迫效应,瓶插寿命与正常瓶插不经水分胁迫的对照切花相同。
