| Research Abstract |
Plants sense light through photoreceptors and induces photomorphogenetic responses through the shade avoidance syndrome. This study aimed toquantify the effect of R:FR within a crop canopy on tillering response and yield in wheat. Tillering dynamics was analyzed by phyllochron interval and site-filling, the relative increase rate of tillers per phyllochron. The field experiments with the different timing of topdressing N, and the different plant densities were conducted. From these results, the relationship between the light quality and morphological responses and yield were analyzed.
