“…The chlorophyll a/b ratio was negatively correlated with the ratio of red to blue light. Galdiano et al (2012) showed that red light strongly promoted chlorophyll b synthesis in Cattleya loddigesii Lindl.. Similar results were also reported for R. glutinosa and Triticum aestivum L. (Dong et al, 2014; Manivannan et al, 2015).…”

The aim of this study was to investigate the effects of light quality on the morphological traits, leaf anatomical characteristics, antioxidant enzyme (superoxide dismutase, catalase, and peroxidase) activities, photosynthetic pigments content, and bioactive compounds (phenols, flavonoids, and polysaccharides) content in Anoectochilus roxburghii. Plants of A. roxburghii were grown under light filtered through four differently colored films for 8 months. The four treatments were red film (RF), blue film (BF), yellow film (YF), and colorless plastic film (control, CK). Compared with the A. roxburghii plants in CK, those in the BF treatment showed significantly greater stem diameter, fresh weight, leaf area, stomatal frequency, chlorophyll content (Chl a, Chl b, Chl a+b), antioxidant enzyme activities, and active compound (polysaccharides, flavones) content. The plants in the RF treatment showed the greatest plant height and phenolics contents. These results show that growing A. roxburghii plants under blue film is a useful technique to improve quality. This technique is conducive to achieving large-scale sustainable production of high-quality plant materials.

“…The use of red light promoted elongation of in vitro cultivated Cattleya loddigesii (ARAÚJO et al 2009), increased shoot length for a Cattleya hybrid (CYBULARZ-URBAN et al 2007) and the use of blue and red LED (light-emitting diodes) caused an increase in Cymbidium growth (TANAKA et al 1998). However, the use of red light reduced the longest root length and increased the mortality of Cattleya loddigesii during the acclimatization phase (GALDIANO JUNIOR et al, 2012).…”

The success in micropropagation of Dendrobium phalaenopsis Deang Suree is high, but when transplanted into the greenhouse, their survival is minimal. To increase survival in production in the present study it was evaluated the effect of intermediate acclimatization for 30 days in a grow room utilizing the following luminosity conditions: 1- white fluorescent light (B) (18.9µmol m-2 s-1); 2- white fluorescent light + red fluorescent light (GRO-LUX(r)) (BV) (14.85µmol m-2 s-1); 3- red fluorescent light (GRO-LUX(r)) (V) (9.45µmol m-2 s-1) and the control plants were accommodated directly in a greenhouse (162.0µmol m-2 s-1). After this the leaves were characterized anatomically and the plants transferred to the control greenhouse. It was evaluated survival percentage and final number of roots, and calculated the relations between the final and initial values of fresh weight, number of leaves, length and diameter of the largest pseudo bulb, number of pseudo bulbs and longest root length. Only plants submitted to red light, were statistically better than the control in relation to the survival percentage and in relation to fresh weight, while the control showed a higher number of roots that plants acclimatized in this luminosity conditions. Intermediate acclimatization, using red light or red + white light, is recommended for D. phalaenopsis Deang Suree.
