The resources for photoperiodically regulated genes for woody plants in Japan is not prepared yet. Wood density is a particularly important trait because it affects other traits such as the mechanical properties of wood and carbon-sequestration performance in woods. The wood density would be affected by photoperiod, whereas the relationship between wood density and the difference of photoperiod is not well understood. We used Larix kaempferi for the research material. The homologs of Constans and Flowerling locus T were isolated and the pattern of circadian rhythms were analyzed. The phenology of cambium activity were observed and the timing of the transition from earlywood to latewood were not affected by the difference of photoperiod.

日本木本植物光周期调控基因资源尚未准备好。木材密度是一个特别重要的性状，因为它会影响其他性状，如木材的机械性能和木材中的固碳性能。木材密度受光周期的影响，但光周期差与木材密度的关系尚不清楚。以日本落叶松为研究材料。分离了Constans和Flowerling T基因座的同源基因，并分析了其昼夜节律模式。形成层活动的物候期不受光周期的影响，早材向晚材转变的时间不受光周期的影响。
