Kinetin delays the fading of cut rose ( Rosa hyb. cv. Golden Wave) flower shoots exposed to water stress conditions. Using leafless flower shoots ( i.e. , a plant system devoid of stomates), we demonstrated that the main initial effect of kinetin was on increasing water uptake and petal growth. Later, kinetin slowed down processes associated with both senescence and stress (RNase activity and dry weight reduction), and maintained petal turgidity for an extended period.
