| 摘 要： | 以牡丹品种洛阳红为试验材料，研究了秋施乙烯利和赤霉素对牡丹萌芽及开花的影响。结果表明：秋施乙烯利可使牡丹的落叶期提前，萌芽期和开花期延迟，且显著降低了开花率，减小了花径，并且增加了畸形花的百分率。秋施GA1可使牡丹落叶期延迟，萌芽期和开花期提前，并提高牡丹的开花率，增大了花径。

| Abstract: | Peony variety LuoYangHong was used to study the effects of application of ethephon and GA_3 in the fall on bud sprouting and flowering of peony. The results show that application of ethephon promoted leaf abscission, delayed bud sprouting and flowering of peony. Furthermore application of ethephon decreased significantly flowering rates and flower diameter of peony, and increased the rates of abnormal flower. GA_3 applied in the fall delayed leaf abscission, promoted bud sprouting and flowering, and increased flowering rates and flower diameter of peony. |
