Morphological observation on floral bud differentiation of Lilium formolongi under night-break condition
The floral bud differentiation of Lilium formoLongi was studied with the method of paraffin section under night-break condition. The results were as follows: the process of floral or terminal bud differentiation could be divided into five phases: undifferentiation phase, flower or inflorescence primordium differentiation , petal differentiation , stamen and pistil differentiation and whole inflorescence formation . The process of floral development contained the first four phases,except the whole inflorescence formation phase. Moreover,based on the observation, the time of 80% inflorescence formation under night-break condition was 25 d. This results could be availabe for promoting blossom of L. formolongi by controlling the illuminative date at night.
