La relevancia ornamental de las especies orquídeas radica en sus características morfológicas. Notylia barkeri Lindl. está catalogada el Apéndice II la Convención sobre Comercio Internacional Especies Amenazadas Fauna y Flora Silvestres. Por tanto, resulta imperativo instituir métodos preservación para salvaguardar su viabilidad a largo plazo. El objetivo fue establecer un protocolo conservación in vitro N. barkeri. Se evaluaron diferentes concentraciones ácido abscísico (0,1 2 mg L-1) ancimidol medio Murashige Skoog. Después 180 días se evaluó porcentaje supervivencia, número longitud brotes, hojas, raíces. mayor supervivencia (85.71 %) observó tratamiento testigo. Mientras que 1 L-1 57.14 %. Los menores porcentajes observaron ancimidol. reduce brotes sin afectar diferencia cuando utilizó Además, redujo Nuestros resultados pueden contribuir esta especie con interés ornamental.

Global biodiversity loss and mass extinction of species have raised serious global concerns, especially in fragile ecosystems. Karst forest, a well-known ecosystem, is served as natural laboratory for biogeographical, ecological, evolutionary, taxonomic research. However, richness distribution patterns karst forests largely remain unclear. Orchidaceae has been regarded the "flagship" group plant diversity. In this study, we use Wanfengshan Nature Reserve southeast Yunnan, China, model to determine conservation status orchids forest by conducting systematic field surveys past three years from 2019 2022. total, identified 78 orchid 35 genera Reserve. The dominant were Bulbophyllum andersonii, Eria coronaria, Nervilia mackinnonii Paphiopedilum micranthum. Multiple life forms also observed, including epiphyte (14.29%), facultative (18.18%), lithophyte (23.38%), terrestrial (44.15%). Orchid showed bimodal pattern varied with altitude, higher was recorded at 1,500–1,600 1,200–1,300 ​m, while minimum below 1,100 ​m. Each independent hill rich 'endemic' species.

Cymbidium are endangered and ornamental orchids, the taxonomy species identification of this genus have been debated due to some overlapping morphological features between taxa limited data being available. The leaf morpho-anatomy 12 from China was investigated using light microscopy paraffin sectioning. Based on a comparative analysis, that varied were selected used for taxonomic differentiation as follows: (1) shape structure leaves could be delimitation. (2) Microscopic characteristics show lacked trichomes displayed polygonal rectangular epidermal cells both surfaces, with larger adaxial more abaxial stigmata. Stomata mostly distributed only side, but sides in mastersii, which exhibited rare amphistomatic type. stomatal complex uniformly tetracytic 11 species, while it observed anomocytic C. floribundum. (3) Anatomically, two distinct midrib configurations identified, shallow V-shape V-shape. mesophyll homogeneous 10 exception layer parenchyma resembling palisade occurring lancifolium qiubeiense. thickness cuticle surface covered by thicker than displaying either smooth or corrugated surface. A fiber bundle six absent other six. In former group, occurred adjacent mastersii hookerianum, epidermis four species. stegmata, conical, spherical silica bodies, associated bundles seven five (C. kanran, defoliatum, floribundum, lancifolium, serratum). Three kinds crystals namely terete bundle, long tube raphide.

Ecological stability together with the suitability of abiotic conditions are crucial for long-term survival any organism and maintenance biodiversity self-sustainable ecosystems relies on species interactions. By influencing resource availability plants affect composition plant communities ultimately ecosystem functioning. Plant-animal interactions very complex include a variety exploitative mutualistic relationships. One most important is that between their pollinators. Coevolution generates clustered links pollen vectors, but pollination reproductive success reduced by increase in specialization plant-animal specialized types sexual deception, which occurs almost exclusively Orchidaceae. In this form mimicry, male insects attracted to orchid flowers chemical compounds resemble insect female sex pheromones pollinate during attempted copulations.
