Lighting from Top and Side Enhances Photosynthesis and Plant Performance by Improving Light Usage Efficiency.

ABSTRACT: Light is a critical environmental factor that influences plant growth and development, ranging from seed germination to flowering and fruiting. This study was carried out to explore how the optimal combination of various lighting directions increases the light usage efficiency and influences the plant morphophysiology, by investigating the plant growth parameters, leaf anatomy, epidermal morphology, stomatal properties, chlorophyll content, key physiological changes, and correlated gene expressions. In closed-type plant growth chambers, rooted cuttings of two chrysanthemum (Chrysanthemum morifolium Ramat.) cultivars, "Pearl Egg" and "Gaya Glory", were subjected to a 10-h photoperiod with 600 μmol∙m-2·s-1 photosynthetic photon flux density (PPFD) provided by light-emitting diodes (LEDs) in
