“…These results agree with those reported in various plant species, such as the tree peony (Paeonia lactiflora) (Ding et al 2010), chrysanthemum (Dendranthema grandiflorum) (Kim et al 2004) and some orchid species (Shin et al 2008;Chung et al 2010;Lin et al 2011). These results are in agreement with the present observation in S. rebaudiana, since the B/R combination was associated with the highest photosynthetic pigment levels.…”

The Effect of Light Quality on Growth and Development of In Vitro Plantlet of Stevia rebaudiana Bertoni

Fluorescent lamps are the most commonly used light source for the in vitro culture of various plant species. However, there are other sources of illumination, such as light-emitting diodes (LEDs), which have proven to be more efficient for in vitro culture. In the present study, we evaluated the effect of LEDs on the in vitro morphogenesis, proliferation of shoots, growth and rooting of Stevia rebaudiana Bertoni. For that, five different sources of light were tested under a 16-h photoperiod: fluorescent lamps (Fl), white LEDs (W), red LEDs (R), blue LEDs (B) and a combination of blue and red LEDs (B/R, 1:1). The proliferation rate was higher with R LEDs compared with Fl light, although shoots have a lower length under R LEDs. Under B/R LEDs, maximum shoot elongation was obtained. During rooting, LEDs did not improve the rooting of shoots but increased the content of photosynthetic pigments, which contributed to the acclimation process of in vitro plantlets. Our results revealed that the spectrum of different light sources produced different effects during the in vitro culture of S. rebaudiana.

“…However, some reports provide evidence for somatic embryogenesis in Cymbidium ensifolium var. misericors, Phalaenopsis Richard Shaffer 'Santa Cruz', Phalaenopsis 'Little Steve', and Oncidium 'Gower Ramsey' (Chang and Chang 1998;Chen and Chang 2000;Chung et al 2010;Kuo et al 2005;Ishii et al 1998). Research has suggested that the process of somatic embryogenesis is part of the early steps of PLBs formation in orchids (Begum et al 1994;Steward and Mapes 1971).…”

This work presents a rapid and reliable micropropagation method for a Lycaste hybrid using a fieldgrown axillary bud culture system. Intact buds (2-4 mm in length) were excised from a mature pseudobulb and were cultured in half-strength MS basal medium, which was supplemented with 0.5 mg l -1 benzyladenine (BA), 1.0 mg l -1 thidiazuron (TDZ) and 2% (w/v) sucrose. After 2 months, the calli exhibited vigorous growth and eventually turned green, forming protocorm-like bodies (PLBs) originating in the surface of each callus. The results of this work reveal that the combination of 0.5 mg l -1 BA and 1.0 mg l -1 TDZ treatments was highly effective in indirectly multiplying shoots from callus-PLB mixed explants, which yielded up to 400 shoots in the fourth time subcultures (within 24 weeks). Histological observations showed the apical meristem of adventitious bud is based on a longitudinal section of a callus sample. Histological and scanning electronic microscopy also indicated that PLBs derived from calli could be regarded as organogenesis but not somatic embryogenesis. Shoots with a length of around 2-3 cm generated in vitro were excised and cultured in MS medium supplemented with 0.5 mg l -1 IBA exhibited the best rooting response (78.3%), and an average of 1.8 roots per explant was produced within 4 weeks.

“…According to Chung et al (2010), light induces plant morphogenesis. Light is a signal that is received by a photoreceptor that then regulates the differentiation and growth of plants (Wang et al, 2001;Muleo and Morini, 2006).…”
