ＰＰ３３３调控唐菖蒲试管苗苗质结果表明：合适浓度的ＰＰ３３３处理可明显地增加愈伤组织芽分化的数量。采用ＰＰ３３３处理的试管苗苗质优于对照，表现为壮苗率高，移栽成活率高，根部、冠部干物重高，根冠比大。经ＰＰ３３３处理的试管苗移栽后长势好，再生苗叶片结构优于对照，成球率明显提高，球茎形成期收缩根的膨大较对照提前 The result of PP333 regulating the seedling quality of Gladiolus plantlets showed that the suitable concentration of PP333 could obviously increase the number of bud differentiation of callus. The quality of in vitro seedling seedlings treated with PP333 was better than that of the control, which showed that the seedling emergence rate was high, the survival rate of transplanting was high, the dry weight of roots and crown was high and the ratio of root and shoot was large. The tube seedlings treated with PP333 grew well after transplanting, the structure of regenerated seedling leaves was better than that of the control, the rate of forming a balloon was significantly increased, and the enlargement of the contracted roots during bulb formation was earlier than that of the control
