Effect on the Growth and Photosynthetic Characteristics of Anthurium andreanum (‘Pink Champion’, ‘Alabama’) under Hydroponic Culture by Different LED Light Spectra

Anthurium andreanum was one of the best indoor ornamental plants. Two cultivars (Pink Champion, Alabama) were used to investigate effects light quality on physiological and biochemical indexes. There six different treatments: Fluorescent Daylight Lamp (CK), RB (100% Blue, 60% R + 40% B, 70% 30% 80% 20% 100% Red) provided by emitting diodes (LED). The results showed that blue beneficial shoot growth dry matter accumulation, photosynthetic rate, soluble sugar, POD activities. Red for synthesis accumulation protein, could promote root growth. ‘Pink Champion’ ‘Alabama’ obtained relatively better morphological parameters, chlorophyll contents, antioxidant enzyme activities in 7:3 6:4 treatments. (POD, SOD) under composite red treatments than monochromatic red, CK whole. Comprehensive evaluation treatment a suitable environment indoors be as preferred ratio production application andreanum.
