瓶插唐菖蒲切花保鲜液试验

ExPERIMENTS ON FLORAL RESERVATIVE OFVASEGLADIOLUS(GLADIOLUS HYSKLOUDUS HORT)

试验结果表明，唐菖蒲（ＧｌａｄｉｏｌｕｓｈｙｂｒｌｄｕｓＨｏｒｔ．）切花的鲜度只有在切花鲜重增加，即吸收量大于蒸散量时才能获得。总开花率，日平均观赏值和保鲜期长短三者呈正相关，单一成份的保鲜液虽然有一定的作用，但不及糖源、杀菌剂及乙烯对抗剂的复合配方为佳；复会配方以蔗糖５％干硝酸银５０＋１０￣－６＋８一ＨＱＳ３００×ｌ０￣－４＋适量酸化剂的复合保鲜剂保鲜效果最佳。

Cut flower spikes of gladiolus (Gladiolus hybr,dus Hort。)were placed in aqueous solutions ofdifferent saIts viz。silver nitrate; 8-HQSin comblnatlOn with sucrose(5%)and organic acids。Flower opening was monitored and vase life was recorded. Water uptake and transpiration rates by fIower spikes was alson1easured.The number of fully opened florets, ornamental value and vase life of cut fIower spikes were significantly increased by the treatments。Amaximum vase life of l2 days was recorded wlth sucrose+silver nitrate+8-HQS + organic acids compared with 5 days for the controls。
