比较了香石竹（Dianthus caryophyllus L.）两个品种衰老花的乙烯和多胺代谢，一个表现出更年期行为（Arthur '），另一个表现出非更年期行为（Killer'）。亚瑟康乃馨在第7天表现出衰老的最初症状，与最大乙烯和CO2产生、乙烯形成酶（EFE）活性的峰值和游离ACC含量相对于初始值的7倍增加相一致。然而，在Killer'康乃馨中，衰老的开始是在收获后15天，并且没有检测到乙烯或CO2峰（.）
We have compared the ethylene and polyamine metabolism of senescing flowers from two cultivars of carnation (Dianthus caryophyllus L.), one showing climacteric (Arthur') and the other nonclimacteric behavior (Killer'). Arthur' carnations showed the first symptoms of senescence at day 7, coinciding with maximum ethylene and CO 2 production, a peak in the ethylene-forming enzyme (EFE) activity, and a 7-fold increase in free ACC content in respect to the initial value. In Killer' carnations, however, onset of senescence was 15 days after harvest, and no ethylene or CO 2 peak was detected (...)
