Abstract
In the present study, we investigated tiller formation in rice cultivated under red radiation (R), red supplemented with 10 % of blue radiation (RB), and white radiation (W). In addition, expression of three genes related to tiller formation, OSH1, MOC1, and OsTB1, was analyzed at both vegetative and reproductive stages. RB promoted the outgrowth of tiller buds and increased tiller numbers significantly. Transcription of MOC1 and OsTB1 in RB was higher than in R, whereas OSH1 expression was independent on radiation quality.
