Cultivars]]>AdugnaBiniam BelewDerbew KassaNegussie 1201221Carnation (Dianthus caryophyllus L.) is very sensitive to external and self generated ethylene. Pulsing with silver thiosulfate (STS) solutions is now widely used commercially. However, silver thiosulfate (STS) solutions contains silver ion which is a potent environmental pollutant. On the other hand, ethanol solution pulsing has been found to be effective in inhibiting ethylene biosynthesis and environmentally safe. Thus, this study was conducted to assess the effect of selected pulsing solutions on the days to bent neck, complete flower bud opening, and flower bud shrinkage occurrence of carnation cultivars (Green-Go and Galy) at Addis Alem, Schecter Yosef Flower Farm and Central Ethiopia. The experiment was laid out in a factorial arrangement with a Complete Randomized Design (CRD) consisting of three replications. The pulsing solutions used for this investigation were silver thiosulfate (STS) (0.2, 0.6 and 1 mM) for 6 h and ethanol (6, 8 and 10 %) for 3 h, both received equal amount of sucrose (10%). In addition, existing practice of the farm (0.4 mM silver thiosulfate (STS) plus 0.3 mM T.O.G®) was used as a standard control. The recorded trials included complete flower bud opening, flower bud shrinkage and bent Neck. Accordingly, the days to complete flower bud opening was prolonged by 0.6 mM silver thiosulfate (STS) plus 25 g sucrose (8.47 days). The days to flower bud shrinkage extended by 0.6 mM silver thiosulfate (STS) plus 25 g sucrose (26.42 days) and being in par with 8% ethanol plus 25 g sucrose (25.39 days) for Green-Go cultivar. Furthermore, days to complete flower bud opening showed a direct association with days to flower bud shrinkage occurrence.]]>Bakhsh, A., M.A. Khan, C.M. Ayyub, M.A. Shah and M.
