芙蓉将栽培品种'Brilliant Red'植物暴露于各种环境因素以确定它们在模拟运输期间对芽脱落的影响。高温（30°C）增加了芽的萌发，并在黑暗储存4天后降低了叶片叶绿素浓度。与在20或30°C下储存的植物相比，在10°C下储存的植物似乎在储存后立即具有更高的视觉质量。与喷水的对照植物相比，4-mM硫代硫酸银（STS）喷雾在减少木槿中C2 H4诱导的芽脱落方面是有效的。硫代硫酸银还有效地减少在10、20或30°C下在黑暗中储存4天的植物的分解。没有观察到响应于STS喷雾的植物毒性，并且在模拟办公室环境中20天后，用STS喷雾的植物仍然没有像对照一样多的芽。因此，STS被证明是控制木槿属植物芽脱落的有效工具。
Hibiscus rosa-sinensisL. cultivar ‘Brilliant Red’ plants were exposed to various environmental factors to determine their effect on bud abscission during simulated shipping. High temperature (30°C) increased bud abscission and decreased leaf chlorophyll concentrations after 4 days in dark storage. Plants stored at 10°C appeared to be of higher visual quality immediately after storage than plants stored at 20 or 30°C.A 4-mM silver thiosulfate (STS) spray was effective in reducing C2H4-induced bud abscission in hibiscus as compared to water-sprayed control plants. Silver thiosulfate was also effective in reducing abscission in plants stored at 10, 20 or 30°C for 4 days in the dark. Phytotoxicity was not observed in response to the STS spray, and after 20 days in a simulated office environment plants sprayed with STS still had not abscised as many buds as controls. Thus, STS proved to be an effective tool for controlling bud abscission in hibiscus plants.
