不同播期对唐菖蒲生物学性状的影响

The effect of different seedtimes on Gladiolus biological characters

对不同播期唐菖蒲植株的生物学性状进行了分析,结果表明:①随着播期的推迟,出苗期、三叶期、六叶期的持续时间会延长;②播期每推迟60 d,种球出苗率显著下降;③年度最高温后播种会明显降低切花率,且播期每推迟30 d,切花率显著下降。

The biological characters of Gladiolus in different seedtimes were analyzed,the results revealed that： ①As the seedtimes prolonged,the duration of emergence of seedlings phase, tri- leafs phase,and six - leafs phase were prolonged. ②If the seedtimes were prolonged 60 days,the rate of emergence of seedilings significantly declined. ③Seeding after the annual highest temperature, the rate of emergence obviously declined, and the rate of cutting flower was significantly declined ff seedtimes were prolonged 30 days.
