In nature, orchid seed germination is obligatory following infection by mycorrhizal fungi, which supplies the developing embryo with water, carbohydrates, vitamins, and minerals, causing the seeds to germinate relatively slowly and at a low germination rate. ,e nonsymbiotic germination of orchid seeds found in 1922 is applicable to in vitro propagation. ,e success of seed germination in vitro is influenced by supplementation with organic compounds. Here, we review the scientific literature in terms of the contents and role of organic supplements in promoting seed germination, protocorm development, and seedling growth in orchids. We systematically collected information from scientific literature databases including Scopus, Google Scholar, and ProQuest, as well as published books and conference proceedings. Various organic compounds, i.e., coconut water (CW), peptone (P), banana homogenate (BH), potato homogenate (PH), chitosan (CHT), tomato juice (TJ), and yeast extract (YE), can promote seed germination and growth and development of various orchids. -
Inter-American Division Fast Facts and Mission Posts Second Quarter 2021
Inter-American Division Fast Facts and Mission Posts Second Quarter 2021 Colombia 1. The Seventh-day Adventist Church in Colombia is comprised of the North Colombian Union Conference and the South Colombian Union Conference. There are 1,758 churches, 889 companies, and 286,131 members. In a population of 50,374,000, there is one member for every 176 people in Colombia. 2. In 1894, Frank C. Kelley went from the United States to Bogota as a self-supporting missionary, paying his expenses by teaching English and selling photographic goods. He went back to the U.S. for a time, married, and then returned to Colombia, but his wife’s health required their return to the U.S. in 1899. The Kelleys returned to Colombia in December 1920, where they worked for two and a half years before permanently returning in 1923. 3. In the early nineteenth century, Adventists went to the islands of San Andres and Providencia, which belong to Colombia but are located north of Panama. In 1901, S. Parker Smith (son of Uriah Smith) and his wife opened a school on San Andres. In 1908, Smith wrote in the Review and Herald that there was a church of 19 members on San Andres and a larger one on Providencia, and that Adventist work was carried largely through the school on the islands. During 1916 and 1917, several colporteurs entered mainland Colombia. 4. About 90% of Colombians are Christian, mostly Roman Catholic (71%–79%), with a significant minority of Protestants (17%). The rest of the population is atheist or agnostic or claim to believe in God but do not follow a specific religion, and a fraction of a percent adhere to non-Christian religions. -
Guanacas Reserve Orchid Diversity
DIVERSITY OF ORCHID SPECIES IN GUANACAS RESERVE, ANTIOQUIA - COLOMBIA Progress Report No. 1 to the Conservation Committee of the American Orchid Society (Project funding from AOS) Dino J. Tuberquia M. Biologist Santiago Cardona Biology student Esteban Dominguez Biology student Fundación Guanacas Bosques de Niebla October 2019 Medellin - Colombia PRESENTATION The preliminary results of the orchideological exploration carried out in the Guanacas reserve, municipality of Santa Rosa de Osos, funded by the Conservation Committee of the American Orchid Society are presented in this report. A first four-day field trip was made during the month of September 2019, in which 50 morphospecies of orchids, belonging to 15 genera, were collected. The material was herbalized and is in the process of identification. The preliminary list of species and photographic file is presented. INTRODUCTION Orchids, without a doubt, constitute not only the group of flowering plants (angiosperms) with the largest number of species in the world, but also one of the most charismatic of the plant kingdom. The particular shapes and attractive colors of its flowers have historically attracted the attention of naturalists, horticulturists, taxonomists, artists, and society in general, which recreates in them, the greatest inspiration that nature could express in a flower. Even for the most profane in the knowledge of plants, the concept of orchid is synonymous with high expression of beauty, design and color. Orchids, like no other flower, have touched the most intimate fiber of sensitivity of human beings, thus becoming a natural reference to admire and contemplate in the plant world. Orchids are part of the flora in almost all the terrestrial ecosystems of the world, and Colombia, due to its geographical position and geological particularities, has been privileged as the representativeness of species of this group, positioning itself between the first two countries, jointly with Ecuador, with greater wealth of orchids in the world (Minambiente and U. -
ORCHID POLLINATION ECOLOGY Orchid Pollination Exploring a Fascinating World by Ron Mchatton
ORCHID POLLINATION ECOLOGY Orchid Pollination Exploring a Fascinating World BY RON MCHATTON [1] The first example of sexual deception in Australian orchids involved the genus Cryptostylis.

In this case, pollinia of Den. infundibulum are placed on the head of the bee while that from the Cymbidium, with much longer column, becomes at- tached to the bee’s central thorax. Because the column of the former species is much shorter, only pollinia placed near the front of the bee will be in a position to contact the stigmatic surface of the Dendrobium column as the bee exits the flower (Du Puy and Cribb 2007). Orchids with large gullet flowers such as Cymbidium are typically pollinated by large carpenter bees and bumblebees are known to pollinate Spiranthes and are implicated in the pollination of northern NT NT U U and some high-elevation species where other large bees are less common or active. 3 4 ERIC H ERIC H Some bees gather oils from flowers rather than nectar or pollen and many orchids [3–4] Sobralia [3] and Cattleya [4], two gen- NO ONE IS REALLY SURE HOW LONG have evolved to attract these pollinators. -

Shashidhar Orchid Events Field Trip Exhibition at CKP Cover Illustration: Laeliocattleya Casitas Springs ‘Linden’ By Dr S.Hegde Beginners Section Dr. K.S. Shashidhar Watch out how you take care of your Orchids!!! There is a feeling among most of the people who have gardening as a hobby that, orchids are difficult plants to grow and need lot of attention and care. Contrary to this belief, they are the easiest to grow provided you ‘listen to them’, ‘watch them’ and provide ‘what they want’. Once they are settled with your care, they live happily and make you enjoy their floral beauty. Well, I know it sounds easy, as the saying goes ‘it is easier said than done’ in most of the cases. But then, to achieve something good we have to make some efforts. Let us see some of the important parameters one has to take into account to successfully grow orchids. Before we look into these factors, give a thought about the way orchid grows in nature and what nature provides them. The whole process of growing orchids involves, trying to copy what nature provides and try to replicate the same (to the extent possible). I will start with selection of plant and move on to briefly discuss the other important factors. -

Assessing the Flowering Genetic Regulatory Network in Neotropical Orchids †
Proceedings Assessing the Flowering Genetic Regulatory Network in Neotropical Orchids † Yesenia Madrigal 1, Diego Ospina-Zapata 1, Andrea Ramírez-Ramírez 1, Juan Fernando Alzate 2 and Natalia Pabón-Mora 1,* 1 Facultad de Ciencias Exactas y Naturales, Instituto de Biología, Universidad de Antioquia, Medellín, Colombia; [email protected] (Y.M.); [email protected] (D.O.-Z.); [email protected] (A.R.-R.) 2 Centro Nacional de Secuenciación Genómica, Sede de Investigación Universitaria, Facultad de Medicina, Universidad de Antioquia, Medellín, Colombia; [email protected] * Correspondence: [email protected]; Tel.: +57-321-772-0164 † Presented at the 1st International Electronic Conference on Plant Science, 1–15 December 2020; Available online: https://iecps2020.sciforum.net/. Published: 30 November 2020 Abstract: During the reproductive transition in flowering plants a vegetative apical meristem (SAM) transforms into an inflorescence meristem (IM) that forms bracts and flowers. In grasses, like rice, a Genetic Regulatory Network (GRN) controlling reproductive transitions has been identified. It includes the integration of promoters and repressors from different gene lineages with active duplication events during angiosperm diversification. With the objective to understand the evolution and expression of flowering GRN in Orchidaceae, we performed comprehensive phylogenetic analyses of all genes from the flowering GRN and analyzed by RT-PCR the expression of targeted homologs in key developmental stages. Our ML results indicate that FT/TFL1, FD, FLC/FUL, SOC1 and AGL24/SVP gene lineages have been subject to multiple duplications in monocots as well as in Orchidaceae. Conversely, FLC genes are lost in Orchidaceae, suggesting major changes in the repression of flowering. -
Viabilidad Y Germinación in Vitro De Taxones De Las Tribus Cymbidieae Y
Rev. Acad. Colomb. Cienc. Ex. Fis. Nat. 43(168):494-501, julio-septiembre de 2019 doi: http://dx.doi.org/10.18257/raccefyn.888 Artículo original Ciencias Naturales Viabilidad y germinación in vitro de taxones de las tribus Cymbidieae y Epidendreae (subfamilia Epidendroideae, Orchidaceae) Adriana Paola Bonilla-Sánchez*, Hilda Rocío Mosquera-Mosquera Grupo de Genética y Biotecnología vegetal y Microbiana, Universidad del Tolima (GEBIUT), Ibagué, Colombia Resumen Las orquídeas Epidendroideae presentan el polen organizado en polinios con diferente grado de compactación; cada polinio puede contener hasta 4 millones de granos de polen. En este estudio se evaluó la viabilidad y la germinación in vitro del polen aglutinado en polinios. Se evaluó la calidad polínica de siete taxones en dos tribus utilizando métodos palinológicos ex vitro (tinción con acetocarmín glicerol al 2 %) y directos (germinación in vitro) en tres medios, M1, M2 y M3. La viabilidad con acetocarmín fue superior al 85 % en los siete taxones estudiados. El mayor porcentaje de germinación in vitro se obtuvo en Catasetum tabulare, con un 16 %; en el resto de taxones los valores oscilaron entre el 2 % y el 5 % a las 72 horas de observación. El medio M3 fue el más exitoso, con 18 y 20 % de germinación en los taxones estudiados. Aunque la viabilidad del polen es alta, presenta tasas muy bajas de germinación, probablemente por el alto grado de compactación y la ausencia de aperturas, lo que la hace lenta y poco efectiva en medios artificiales. Los resultados ratificaron que no todo el polen viable germina, y que existe un alto grado de especificidad y dependencia frente a las sustancias estimuladoras de la germinación del polen provenientes del estigma de las orquídeas, lo que hace necesario seguir profundizando en el análisis de la biología del polen de la subfamilia Epidendroideae para comprender un poco más sus procesos de multiplicación natural. -
Crassulacean Acid Metabolism in Epiphytic Orchids: Current Knowledge, Future Perspectives
4 Crassulacean Acid Metabolism in Epiphytic Orchids: Current Knowledge, Future Perspectives Gilberto Barbante Kerbauy, Cassia Ayumi Takahashi, Alejandra Matiz Lopez, Aline Tiemi Matsumura, Leonardo Hamachi, Lucas Macedo Félix, Paula Natália Pereira, Luciano Freschi and Helenice Mercier São Paulo University, Brazil 1. Introduction 1.1 Crassulacean Acid Metabolism (CAM) Crassulacean Acid Metabolism (CAM) is one of three photosynthetic assimilation pathways of atmospheric CO2, together with the photosynthetic pathways C3 and C4 (Silvera et al., 2010a). The CAM is characterized by the temporal separation between CO2 fixation and its assimilation into organic compounds. In CAM plants, CO2 is fixed during the dark period through the action of the enzyme phosphoenolpyruvate carboxylase (PEPC), which uses CO2 for carboxylation of phosphoenolpyruvate (PEP), giving rise to oxaloacetate (OAA). The OAA formed is converted into malate by the action of malate dehydrogenase (MDH). Then, this organic acid is transported to the vacuole along with H+ ions, causing the typical nocturnal acidification of CAM plants. During the light period, the decarboxylation of malate and refixation of the CO2 by the enzyme ribulose bisphosphate carboxylase oxygenase (RUBISCO - C3 cycle) takes place in the cytosol, causing a decrease of acidity in the tissues (Herrera, 2009; Luttge, 2004; Silvera et al., 2010b) (Figure 1). The CAM pathway can be separated into four phases (Luttge, 2004; Osmond, 1978; Silvera et al., 2010b). Phase I is characterized by the opening of stomata during the night, the uptake and subsequent fixation of atmospheric CO2 by PEPC in the cytosol and the formation of organic acids, such as malate. Phase II consists of fixing CO2 by the enzyme RUBISCO and PEPC concurrently, a phase characterized essentially by the decrease in the activity of PEPC and the start of the activity of RUBISCO.
