“…Likewise, their phenylethanoid glycoside production is better than that attained when fluorescent lamps or monochromic green, red, or yellow lights are used. Miyashita et al (1997) have reported that the growth of single-node potato explants is affected by monochromic red light of 11, 15, 28, 47 or 64 pmol m -2 s -1. In the current study, blue-light treatment did not promote Table 1.…”

“…An LED lighting system has several benefits including long life, no heat byproduct, small mass, and monochromic spectral quality, and thus can be easily used to promote stem elongation, lateral branching, flower stalk elongation, or variations in leaf pigment content (Bula et al, 1991 ;Brown et al, 1995;Miyashita et al, 1997;Tanaka et al, 1998).

Light quality affectsin Vitro growth of grape ‘Teleki 5BB’

We investigated the effects of various qualities of light-emitting diode (LED) light sources on the growth and carbohydrate accumulation of grape rootstock 'Teleki 5BB' cultured in vitro. Shoot fresh and dry weights and net photosynthetic rates were increased when plants were exposed to fluorescent lighting (control), red light, or a mixture of blue plus red, but were unaffected by blueonly radiation. Shoot elongation was significantly stimulated by red light whereas the combination of blue and red light was associated with the shortest shoots. However, the number of nodes did not differ among these treatments. Under monochromic blue or red light, sugar content and starch accumulation increased under the mixed-radiation treatment.

“…Similarly, growth, morphology and differentiation of in vitro plantlets are also affected by light (Economou and Read, 1987). Red light has been shown to significantly enhance stem elongation in Pelargonium plantlets (Appelgren, 1991); higher root to shoot ratio in potato plantlets (Aksenova et al, 1994) and affect morphology rather than growth of potato plantlets when used as main light source (Miyashita et al, 1995).…”

-The plant Empetrum nigrum, valued in the traditional system of medicine, is well known for its antibacterial, antifungal, and antioxidant properties. In the present work, the effect of removal of shoot apical meristem (SAM) on shoot proliferation was studied. It was observed that removal of SAM promoted shoot proliferation whereas intact tip resulted in higher survival percentage. Further, the effect of different concentrations of BA on above was also studied. During root formation the effect of light quality after treatment with IBA was investigated. For rooting, continuous red light without IBA resulted in maximum rooting percentage. The above factors when taken into consideration during micropropagation of this endangered plant can result in healthier plantlets. The results show that the species could be successfully conserved by in vitro propagation system.

“…The effects of light intensity of different lighting sources on the growth and development of plants were also the concern of some studies of Gilslerod and Mortensen (1997), Miyashita et al (1997), and Nhut (2002) [20 -22]. In these studies, higher light intensities gave the best plant growth.…”

An efficient lighting system (Compact 3U) was successfully applied to the micropropagation of gloxinia and potato plants. To compare the in vitro growth of plantlets under Neon and Compact 3U lighting systems, gloxinia and potato shoots were cultured on suitable media at different light intensities: (1) . The results obtained after 3 weeks of in vitro culture and 6 weeks of acclimatization in a greenhouse showed that the growth of plantlets cultured under the Compact 3U system was better than that under Neon lighting system. The Compact 3U lighting source had a highly significant effect on the growth and development of gloxinia and potato plantlets. Besides, the data in our study also indicated that gloxinia and potato plantlets adapted differently to different lighting sources and light intensities.
