Schefflera arboricola is a member of the family Araliaceae and one of the most popular foliage plants used to landscape interiors. Generally, low light intensities, typical for indoors, increase leaf drop and reduce leaf quality ( Conover and

et al., 2014 ). Insufficient light intensity may limit the assimilation of plant carbon and reduce the activity of carbon assimilation enzymes ( Allen and Ort, 2001 ; Dai et al., 2009 ), thereby reducing the net photosynthetic rate ( P n ), effective

developmental and yield responses to a wide range of temperature and light intensities obtained at different planting times were examined to determine the responses of these variables to mean daily temperature and cumulative daily light intensity. Materials

et al. (2013) , shoot removal (harvest) not only removes apical dominance and correlative inhibition, but also leads to 1) increased light intensity reaching the axillary bud; and 2) changed spectrum of light reaching the bud (particularly a higher

complicated by an interaction between temperature and light; thus, light intensity can also be used to manipulate the timing of flowering for the nobile dendrobium. Wang (1995) reported that the number of days in darkness or at a low PPF delayed
