Platycerium is a genus of large, attractive epiphytic ferns that mainly grow on trees. In Singapore, two species have been known - P. coronarium (Koenig) Desv. and P. ridleyi Christ. The former commonly grows on forest and undisturbed wayside trees (Wee, 1978) while the latter is rare. P. ridleyi was once collected from tall trees in the primary jungle of Bukit Timah, but it is now thought to be extinct there (Holttum, 1966; Wee, 1984). During the 1970s and 1980s epiphytes were systematically… Expand
Chapter 8 In Vitro Regeneration Systems of Platycerium
The staghorn fern genus, Platycerium Desv., belongs to the family Polypodiaceae. It is an epiphytic genus of pantropical distribution, consisting of 15–18 species, cultivated worldwide because ofExpand
Regeneración de esporofitos de Platycerium bifurcatum (Cav.) C.Chr. a partir de esporas germinadas in vitro
It was defined that with 2% sodium hypochlorite and 15 minutes of exposure was reduced the percentages of contamination and was not affected spore germination, which allowed select the liquid culture medium for their growth and multiplication. Expand
In Vitro Regeneration Systems of Platycerium
In this review, regeneration systems of Platycerium using in vitro techniques are summarized and compared to those among other fern species, and the influence of initial explants, culture media, plant growth regulators, wounding, etc., on morphogenesis, including apospory and apogamy is presented.

In vitro propagation of Platycerium bifurcatum (Cav.) C. Chr. via green globular body initiation.
Using the proposed propagation procedures, it was possible to obtain an estimated production of about 170 sporophytes per initial leaf explant during a 32-week culturing period, and the survival rate of the plants was 88% or higher. Expand
Gametophyte morphology of Platycerium andinum Baker and Platycerium wandae Racif.
In both species, some spores germinate inside the sporangial capsule (intra-sporangial germination) and new information on morphogenesis in the genus Platycerium is provided. Expand
Role of ethylene in the production of sporophytes from Platycerium coronarium (Koenig) desv. frond and rhizome pieces cultured in Vitro
The biosynthetic pathway of ethylene in the fern P. coronarium appears to be different from that of higher plants but similar to that of some other ferns. Expand
Regeneration from Platycerium bifurcatum scales in vitro was observed for the first time and Sucrose enhanced scale viability and regeneration, and promoted rhizoid development on outgrowths, but sucrose concentrations greater than 0.1% tended to inhibit apospory. Expand
Biotechnology in Clone Gametophytes: Future Perspectives in Homosporous Ferns
It is described that the clone gametophytes of Anemia rotundifolia, Cyathea spinulosa and Pronephrium nudatum perform sexual expression and mating to augment the sporophyte production. Expand
Isolation and Characterization of a Novel SOMATIC EMBRYOGENESIS RECEPTOR KINASE Gene Expressed in the Fern Adiantum capillus-veneris During Shoot Regeneration In Vitro
The results indicate that the AcvSERK1 gene is a good marker for differentiated cells that are capable of forming embryos in A. capillus-veneris, suggesting that SERK genes have played an important role in embryogenesis during the evolution of land plants. Expand
