| Research Abstract |
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.
