摘　　要：以洋桔梗‘露西塔’(Eustoma grandiflorum‘Lucetta’)切花为试材,探讨了不同浓度纳米银(Nano silver,NS)和蔗糖的组合溶液瓶插处理对其的保鲜作用.结果表明与对照(去离子水)和单用蔗糖处理相比,1.0~10.0 mg/L NS+15.0 g/L蔗糖处理均可显著延长该切花的瓶插寿命,并能提升观赏品质.其中1.0 mg/L NS+15.0 g/L蔗糖和2.0 mg/L NS+15.0 g/L蔗糖2个处理的保鲜效果尤为突出,经此2个处理的洋梗切花瓶插寿命分别比对照(6.6 d)延长18.9 d和18.3 d,并可显著提高该切花的日观赏值,促进花枝水分吸收和维持较高的鲜质量.The preservation effects of vase treatments with different combinations of nano-silver(NS)and sucrose solutions on cut lisianthus(Eustoma grandiflorum‘Lucetta’)flowers were investigated.The results showed that 1.0~10.0 mg/L NS plus 15.0 g/L sucrose could significantly prolong vase life and enhance vase performance of cut lisianthus flowers,compared with control(i.e.,held in deionized water)and sucrose solely.In particular,the freshness-keeping effects of treatments with 1 or 2 mg/L NS plus 15.0 g/L sucrose were the most effective among all treatments.The vase lives of cut lisianthus flowers treated with 1 mg/L NS+15.0 g/L sucrose and 2 mg/L NS+15.0 g/L sucrose were longer by 18.9 d and 18.3 d than that of the control(6.6 d),respectively.Moreover,the two combination treatments could significantly increase their daily ornamental value,improve the water uptake,and maintain a much higher fresh weight than those of the control and other treatments.
