carbon and nitrogen are the two elements that most affect plant organogenesis. in vitro, usually as part of the macronutrients. some anecdotal evidence from the literature suggests that the ammonium (nh4+) to nitrate (no3–) ratio may affect orchid organogenesis. in this study, to test this hypothesis, different nh4+: no3– ratios were tested on the development of protocorm-like bodies (plbs) of ...

The effects of cattle manure vermicompost on the growth and productivity of cymbidium (Cymbidium sp.) plants were evaluated under shade conditions. Cymbidium was grown in a container medium including 50% pumice, 30% charcoal, 10% vermiculite and 10% peat moss, which was basic plant growth medium substituted with 10%, 20%, 30% and 40% (by volume) vermicompost. The control consisted of container ...

Understanding the genetic resources and diversity is very important for the breeding programs and improvement of several economically important orchids like Cymbidium. Karyomorphological studies have been carried out on seven Cymbidium species, Cymbidium aloifolium (Linnaeus, 1753), Cymbidium devonianum Paxton,1843, Cymbidium elegans Lindley, 1828, Cymbidium iridioides D. Don, 1825, Cymbidium l...

This paper to study the potential of expressing ink-and-wash painting through interaction, and present a direction that can coincide with modern paintings by developing ink-and-wash painting from a traditional aspect through analyzing the theories and tech-niques instilled in my works.This work is an interactive visualization of an oriental cymbidium using modern technology which our oriental a...

Orchids are affected by many viruses resulting in poor growth, yield and quality, and an overall decline in population. Cymbidium mosaic virus (CymMV) is one of the common orchid viruses found in Cymbidium species but it infects different orchid genera. In this study Cymbidium aloifolium was propagated in vitro using MS medium at different strength (1.0, ½, and ¼) with or without 0.5 mg/l BAP (...

We have previously shown that human corneal epithelial cells sense and react to nanoscale substrate topographic stimuli [Teixeira AI, Abrams GA, Bertics PJ, Murphy CJ, Nealey PF.

Cymbidium erythrostylum Rolfe is one of the most beautiful species genus cymbidium which used as a cut flower or indoor plant. However, it was registered rare even in its original habitat. This study carried out to develop protocol for vitro propagation C. erythrostilum. We protosomes obtained by asymbiotic germination seed on 1/2 Murashige and Skoog nutrient medium (MS) supplemented with 1 mg/...

Cymbidium, one of the most important orchid genera in horticulture, can be classified into epiphytic and terrestrial species. Generally, epiphytic Cymbidium seedlings can be easily propagated by tissue culture, but terrestrial seedlings are difficult to propagate. To date, the molecular mechanisms underlying the differences in the ease with which terrestrial and epiphytic cymbidiums can be prop...
