摘要:
 为明确自然生长条件下芍药花芽感应低温的始期，以大田地栽的不同花型、不同花期4个品种芍药为研究对象，连续2 a观察其在北京地区冬季土壤自然封冻始期花芽所处的发育状态，对比其在山东菏泽地区1 a的分化状态，探讨不同品种可接受低温时花芽分化状态的规律性，为芍药生产栽培提供参考。结果表明，冬季土壤自然封冻始期芍药花芽发育状态与翌年花期相关，花芽分化程度越高，花期越早；与花型间无明显联系；芍药花芽处于雌蕊原基分化期时可感应低温，花期较晚的品种花芽处于雄蕊原基分化期时亦可感应低温。
Abstract:
 To clarify floral bud differentiation stage in the initial period of soil naturally frozen in winter,4 field peony cultivars in different flower types and different flowering time were observed for their development states during the initial stage of soil naturally frozen.The experiments were conduct in Beijing for two consecutive years (2013-2014),and then the results were contrasted with the floral bud differentiation state observed in Heze for one year (2014),expecting to figure out the suitable floral bud differentiation acceptable to the chilling treatment in Paeonia lactiflora to provide guidance for the production and cultivation of herbaceous peony.The results showed that the floral bud conditions in the initial stage of soil naturally frozen were associated with flowering date of the next year; the early-flowering cultivars had the higher flower bud differentiation.No obvious correlation was observed among the cultivars with different flower types.All peony cultivars could be acceptable to the chilling treatment when in the formation of pistil primordia,late-flowering cultivars could also be acceptable to the chilling treatment when in the formation of stamen primordia.
