WebIt has been generally thought that in ethylene-sensitive plants such as carnations, senescence proceeds irreversibly once the tissues have entered the climacteric phase. While pre-climacteric petal tissues have a lower sensitivity to ethylene, these tissues are converted to the climacteric phase at a critical point during flower development. WebJul 17, 1998 · The climacteric pattern was more obvious when the data were expressed on a per flower basis (Fig. 6 b) than when they were expressed on a fresh mass basis (Fig. 6 a). The highest ethylene production among the cultivars examined was that of `Bronze' (6 nl.g fm −1 .h −1 , 10 nl.h −1 per flower).

WebPetunia flowers, among others, are classified as climacteric based on the presence of an increased rate of ethylene production during flower senescence. In contrast, flowers such as daylily are categorized as non-climacteric, because of their insensitivity to ethylene during flower senescence (Panavas, et al., 1998).
