【摘要】 目的 :对南京七仙山玫瑰园区的 4个玫瑰品种的植物学形态和开花习性进行比较 ,建立品种的鉴别方法 ,了解不同品种间的质量差异 ,以利于更好地发展生产与综合加工利用。方法 :采用田间观察与室内实验相结合 ,对花和花芽进行解剖观察 ,同时对植物学特征和开花习性进行观察。结果和结论 :4个品种的植物学特征存在显著差异 ;花芽分化过程可分为营养锥的转变、萼片原基的形成、花瓣原基形成、雄蕊形成及雌蕊形成 5个阶段 ;单花开放的过程可分为蕾期、露瓣期、初花期、盛花期和末花期及相应的物候标志 ;以香味为衡量标准 ,传统玫瑰品种质量较好。更多还原

【Abstract】 Objective: To establish identifying method for further development and utilization by studying botanic morphology and blooming characteristics of four varieties of roses in jiangsu province. Method: Flower-bud and flower-form were observed by dissection and plant modality and blooming process were investigated. Result and Conclusion:The flower form and plant modality was obviously different among the 4 varieties of roses;The process of differentiation of flower-bud could be divided into five stages: the transformation of nutritive growth cone, the occurrence and development of sepal, formation of petal primordium, formation of pistil and stamen. The blooming process was made up of flower-bud period, display-petal period, initiating blooming period, blooming period, withering period and corresponding biological marks.更多还原
