Micropropagation of Catasetum integerrimum Hook (Orchidaceae) through seed germination and direct shoot regeneration from pseudobulbs and roots

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

Some species of the Orchidaceae family are used in Mexican traditional medicine. However, there are no current and critical compilations of the medicinal uses and pharmacological effects of the members of the Orchidaceae family. This review provides a current, critical, and comprehensive analysis of the traditional medicinal uses, pharmacological reports, and active compounds isolated from Mexican orchids. A total of 62 Mexican orchids with medicinal potential have been recorded, of which 14 have scientific evidence. The remaining 48 plant species have ethnomedicinal information but have not been validated with scientific studies. These orchids are distributed in 14 states of the Mexican Republic, mainly in the southern region of Mexico. The most common pharmacological activities reported are anti-inflammatory, vasorelaxant, antinociceptive, antioxidant, spasmolytic, antihypertensive, and hallucinogenic activities. It is necessary to increase the number of pharmacological, phytochemical, and toxicological studies with medicinal orchids from Mexico because there are scientific studies on only 22.5% of these species. In further studies, it will be possible to evaluate the pharmacological effects of Mexican orchids in clinical trials. In addition, the mechanisms of action by which plant extracts and their active compounds exert medicinal effects remain to be studied. Plant extracts from orchids and their active compounds show promising antinociceptive and spasmolytic effects, respectively.
