The effects of the supplementary and night-interrupting 10 μmol∙m⁻²∙s⁻¹ PPFD B light on the flowering of kalanchoe (Kalanchoe blossfeldiana ‘Rudak’), after 60 days of exposure to the photoperiodic light treatments: The morphology (A); leaf color charts (B); and flower color charts (C) [The color charts of leaves and flowers were analyzed by ‘Munsell Colortell System’; e.g., in ‘5GY/5/4’, ‘5GY’ indicates ‘hue’, ‘5’ indicates ‘value’ (the larger the value, the lighter the color), and ‘4’ indicates ‘chroma’ (the larger the value, the brighter the color)] (See Figure 2 for details on the photoperiodic treatments with B light).
