摘　　要：为提高不同规格种球的利用率,找出可用于优良切花生产的种球,试验参照国际常用分级标准将两个供试唐菖蒲品种种球分成3类,再将3类种球按照横纵径比大小划分成5个亚类进行栽培试验,观察各处理的植株物候期、切花品质及发病率。品种普里西拉种球直径为3.8 cm≤d〈5.0 cm、横纵径比值0.9~1.5,植株生长势强,开花相对较早,综合指标较好,是可用于切花栽培的优良种球。品种蓝精灵在参试等级内退化现象不明显,参试等级均可产生优良切花,但当横纵径比大于1.8时,普里西拉和蓝精灵两品种病情指数均有显著升高。In order to raise the bulb efficiency of the different sizes,bulbs of two tested gladiolus cultivars were divided into three different grades according to the commonly used standards,then each grade was divided into five subgroups by transverse to longitudinal diameter（T/L） ratio.The characters,such as plant phenophase,quality of cut flower and the incidence of disease in the plant growing and cultivation progress were observed.The results showed that the diameter between 3.8 cm and 5.1 cm,and T/L ratio between 0.9 and 1.5 were the best for the cultivars of Priscilla.Cultivars of Blue Spirit showed no significant degradation in the tested grades,the bulbs could produce the first rank cut flower.However,when the T/L ratio was greater than 1.8 cm,the disease index of the two tested cultivars was raised remarkably.
