plants have receptors for blue, green, and ultraviolet light (phototropins and cryptochrome) and R/FR receptors (phytochromes). Different photoreceptors can induce distinctive morphological and physiological responses that allow adaptation to different

phytochrome photoequilibrium was estimated according to Sager et al. 1988 ( Fig. 1 ). Supplemental lighting provided by HPS lamps was used for all plants from 0800 to 1700 hr , delivering a photosynthetic photon flux ( PPF ) of 60 to 90 μmol·m −2 ·s −1 at

( Girault et al., 2008 ). Changing red:far-red ratio affects the phytochrome status ( Franklin and Whitelam, 2005 ). The contrast between the current findings (no effect of red:far-red at bud level on budbreak) to literature reporting decreased budbreak when
