Lilium formolongi 'Fl August' plantlets with scale-leaves and scale-bulb were treated at 10, 15, 20, $25^{circ}C$ for 15, 30, or 45 days and planted in February, March, April and May. In the April planting, flowering percentage was below 10% and in the May planting no flowering occurred. Sprouting and flowering percentages were lower at the late planting times. Days to flowering of the April planting was 110.8 days compared to 128 days for the February planting. Plant height and numbers of leaves were reduced to 7.2 in May planting, compared to 40.5 leaves in February planting, and almost no flowers emerged in either the April or May plantings. Plantlets exposed to 10 or $15^{circ}C$ flowered at 80 percent or higher at all treatment durations, but at 20 or $25^{circ}C$ flowering percentages were lower, with 30% or less in the $25^{circ}C$ treatment. In the $15^{circ}C$ treatment days to flowering were less than 100 days, while the number of flowers and flower bud differentiation were greatest in the $15^{circ}C$ treatment. Cytokinin and auxin were analyzed in bulblets grown at 15, 20 and $25^{circ}C$. T-zeatin content was three times greater in the $15^{circ}C$ treatment than at $25^{circ}C$, but the content of indoleacetic acid (IAA) was less at $15^{circ}C$ than at 20 and $25^{circ}C$. In the $15^{circ}C$ treatment, T-zeatin content was about twice the IAA content in the scale- bulblet. The auxin and cytokinin balance may affect flower bud differentiation. $15^{circ}C$ with 30 days was most effective for flowering in scale-bulblet and planting of February and March were effective for flowering too.
