摘  要：
[目的]研究外源6-BA、GA3和CEPA不同配比对唐菖蒲种球休眠的影响。[方法]以唐菖蒲"江山美人"及"西伯利亚"品种种球为试材,选用6-BA、GA3和CEPA配制成4种不同浓度梯度(6-BA50 mg/L+GA3100 mg/L+CEPA3%,6-BA100 mg/L+GA3100mg/L+CEPA3%,6-BA200 mg/L+GA3100 mg/L+CEPA3%,6-BA400 mg/L+GA3100 mg/L+CEPA3%)的10%丙酮溶液,对进入休眠的唐菖蒲种球进行浸泡处理,观察不同处理下不同品种的种球发芽情况。以清水处理为对照(CK)。[结果]4种处理均有助于打破唐菖蒲种球鳞茎的休眠,品种间存在一定的差异。其中,6-BA400 mg/L+GA3100 mg/L+CEPA3%的10%的丙酮溶液处理效果最佳。该处理"江山美人"种球在50 d时发芽率达到60%,明显高于CK(10%),在70 d时发芽率达到95%,明显高于CK(55%);"西伯利亚"种球在70 d时发芽率达到80%,明显高于CK(40%)。[结论]6-BA400 mg/L+GA3100 mg/L+CEPA3%的10%的丙酮溶液最有助于打破唐菖蒲"江山美人"和"西伯利亚"种球的休眠,提高发芽率。

摘  要：
[Objective] The research aimed to study the effects of different ratio of 6-BA,GA3 and CEPA on the dormancy of Gladiolus hybridus Hort.bulb.[Method] Gladiolus hybridus Hort.bulbs were soaked in 10% acetone solution with 4 different ratio of GA3,6-BA and CEPA(6-BA 50 mg/ L +GA3 100 mg/ L+ CEPA 3%,6-BA 100 mg/ L +GA3 100 mg/ L+ CEPA 3%,6-BA 200 mg/ L +GA3 100 mg/ L+ CEPA 3%,6-BA 400 mg/ L +GA3 100 mg/ L+ CEPA 3%),and their germination status were observed.The test was made by taking clear water as CK.[ Result] The 4 treatments were all helpful to break the dormancy of Gladiolus hybridus Hort.bulb,and there were differences between species.The effects of 10% acetone solution with 6-BA 400 mg/ L+ GA3100 mg/ L+CEPA 3% was the best treatment.Under this treatment,the germination rate of the Country Beauty bulb reached 60% after treating for 50 d,and reached 95% after treating for 70 d,being obviously higher than that of CK(55%).The germination rate of Siberia bulb reached 80% after treating for 70 d,being obviously higher than that of CK(55%).[Conclusion] The 10% acetone solution with 6-BA 400 mg/ L+ GA3100 mg/ L+CEPA 3% was most helpful to break the dormancy of Gladiolus hybridus Hort.bulb and increased its germination rate.
