摘要:

以新铁炮百合‘雷山’(Lilium formolongi‘Raizan’)为试材,利用石蜡切片和扫描电子显微技术,对百合花芽分化的过程进行了形态学观察。结果表明:‘雷山’低温贮藏期间鳞茎内顶端生长点尚未开始花芽分化,栽植后20~30d花芽分化开始进行,并在栽植后50~60d完成花芽分化,整个花芽分化过程约需40d。其分化进程可分为花芽未分化期、花芽分化初期、花序原基和小花原基分化期、花器官分化期、整个花序形成期五个时期。

Abstract:

Anatomic observations were made in the terminal bud of Lilium formolongi cv. Raizan during flower bud differentiation with the paraffin sections and scanning electron microscope (SEM). The results indicated that flower bud differentiation began at 20~30 days and finished at 50~60 days after planting. The process of flower bud differentiation lasted for about 40 days and could be divided into five stages, i.e. Undifferentiation phase, Initial differentiation phase, Inflorescence and small floral primordium differentiation phase, Flower organ differentiation phase, The whole inflorescence formation.

Key words: Lilium formolongi, Flower bud differentiation, Morphology and anatomy
