Breaking dormancy in micropropagated bulblets of Lilium japonicum using gibberellic acid4

Two sizes (4-8 and 8-12mm diam.) of micropropagated bulblets were immersed in 0 (water), 2, 20 and 200ppm gibberellic acid4 for 2 and 20 hrs or exposed to 5 deg C for 60 days. Subsequently, the bulblets were grown at 25 deg C under a 12-hr photoperiod for 60 days. In both sizes, although bulblets im...

Summary:Two sizes (4-8 and 8-12mm diam.) of micropropagated bulblets were immersed in 0 (water), 2, 20 and 200ppm gibberellic acid4 for 2 and 20 hrs or exposed to 5 deg C for 60 days. Subsequently, the bulblets were grown at 25 deg C under a 12-hr photoperiod for 60 days. In both sizes, although bulblets immersed in 200ppm were emerged as chilled and those had more scale leaves than chilled, the leaves were small and the weight of bulblet were not decreased.
