摘要：

采用石蜡切片法观察了卡特兰‘Green World’花芽的形态发生和结构发育过程。研究表明：在北方温室环境条件下，卡特兰花芽分化从7月初花序原基分化开始至9月下旬合蕊柱及花粉块形成历时约3个月。其过程可分为6个时期：未分化期、花序原基分化期、花蕾原基分化期、萼片原基分化期、花瓣原基分化期、合蕊柱及花粉块分化期。其中，花蕾原基分化期、合蕊柱及花粉块分化期历时长，分化较慢，其它时期历时短，分化较快。自萼片原基分化期开始，新生植株生长已基本停止。

Abstract: The flower bud differentiation process of Blc.Sung Ya Green‘Green World’ was studied by the method of paraffin cut.The results showed that the flower bud differentiation process lasted for less than three months from the start of inflorescence primordia differentiation in early July to column and pollinia formation in the end of September under the greenhouse climate condition in North China. The process could be divided into 6 phases: undifferentiation phase, inflorescence primordium differentiation phase, flower differentiation phase, sepal differentiation phase, petal differentiation phase, and column and pollinia differentiation phase. The phases of flower differentiation, column and pollinia differentiation were relatively longer. The new plant finished its growth when sepal differentiation phase begun.

Key words: Cattleya labiata, flower bud, morphological differentiation
