2、件。結(jié)果表明,牡丹切花噴涂處理的最佳條件為水性丙烯酸82.95g·L、茶樹精油0.65-1mL·L,持續(xù)噴涂10.28min。按此條件進(jìn)行驗(yàn)證,測得牡丹切花常溫貯藏5d后的花瓣總色差值為2.15,對照組色差為6.64;該處理能增加切花的觀賞時(shí)間,降低失水率和最大花徑皺縮率,明顯改善花瓣的物理特性,并在一定程度上降低花瓣腐爛指數(shù)。關(guān)鍵詞:牡丹;切花;塑化覆膜;水性丙烯酸樹脂;茶樹精油中圖分類號:S685.11文獻(xiàn)標(biāo)志碼:A文章編號:0513-353X(2016)04-0796-11EffectsofApplyingaPlasticizedCoatingofWa
