Abstract:
Taking cut waxflowers which was highly sensitive to ethylene as material,they were pretreated for 24 h with 10 and 20 mg/L nano-silver (NS) or 0.5 mmol/L silver thiosulfate (STS) solution and using de-ioned (DI) water as control,then immediately placed in vases containing DI water,and exposed to 5 μL/L ethylene for 24 h.The changes in ornamental quality,vase life and flower abscission rate of cut waxflowers during their vase period were investigated.The results showed that exogenous ethylene treatments caused quick wilting and abscission of flowers and obvious inhibition in flower opening of cut waxflowers.Both NS and STS pretreatments could significantly alleviate above harmful effects of exogenous ethylene on cut waxflowers,and the STS treatment was the best and 10 mg/L NS treatment was in second place.Additionally,the distribution of Ag in cut waxflowers after pretreated with 10 mg/L NS and 0.5 mmol/L STS,determined by Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES),demonstrated that Ag could be found in stem end,top of stem,petals and leaves of cut waxflowers pretreated with both STS and NS.However,Ag content in stem end of cut waxflowers pretreated with NS was significantly higher than with STS,while Ag content in their petals of the former was significantly lower than that of the latter.
