| Abstract: | Using gradient illumination time,the flowering of Lilium formolongi was studied.The results showed that Lilium formolongi belonged among the absolute long-day plant,and its critical dark period was about 11.5 h.The growth rate of bud length showed S curve with illumination time passing for the illumination time which were longer than 12.5 h.Moreover,the corresponding illumination time of S curve turning point was 14.5 h. |
