The Genus Brassavola, (L.) R.Br
The Genus Brassavola, (L.) R.Br. in W.T.Aiton, Hortus Kew. 5: 216 (1813) Type: Brassavola [B.] cucullata [bra-SAH-vo-la kyoo-kyoo-LAH-ta] There are 28 species (OrchidWiz [update Dec 2017]) that are epiphytes and sometimes lithophytes at elevations of from sea level to 3300 ft (1000 m) from Mexico, southern Caribbean islands to northern Argentina in moist or wet montane forests, mangroves, rocky crevices and cliff faces. They are most fragrant at night and many with a citrus smell. The genus is characterized by very small pencil-like pseudobulbs, often forming large clumps; a single, fleshy, apical, sub-terete leaf and the inflorescence produced form the apex of the pseudobulb. The inflorescence carries from a single to a few large flowers. The floral characteristics are elongate narrow similar sepals and petals, the base of the lip usually tightly rolled around at least a portion of the column which carries 12, sometimes eight unequal pollina with prominent opaque caudicles. The flowers usually occur, as a rule, in spring, summer and fall. The flowers are generally yellow to greenish white with a mostly white lip. It is not unusual for dark spots, usually purple, to be in the region where the sepals, petals, and lip join the stem (claw). This spotting is a dominant generic trait in Brassavola nodose. They are easily cultivated under intermediate conditions. Although this is a relatively small genus (28 species), the species show an unusually close relationship with one another in their floral patterns, coloration, and column structure making identification difficult, key to know where the plants were collected. -

Clonal Propagation of Phalaenopsis a Dissertation
CLONAL PROPAGATION OF PHALAENOPSIS A DISSERTATION SUBMITTED TO THE GRADUATE DIVISION OF THE UNIVERSITY OF HAWAII IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY IN HORTICULTURE MAY 1974 By Oradee Intuwong DISSERTATION COMMITTEE: Yoneo Sagawa, Chairman Haruyuki Kamemoto Charles H. Lamoureux Henry Y. Nakasone John T. Kunisaki Marion 0. Mapes We certify that we have read this dissertation and that in our opinion it is satisfactory in scope and quality as a dissertation for the degree of Doctor of Philosophy in Horticulture. DISSERTATION COMMITTEE CfaU6 Chairman 01j- <XAs<^<rv^ & ■ . ACKNOWLEDGEMENT The author expresses deep appreciation to the East-West Center, Harold L. Lyon Arboretum, Hawaii Agricultural Experiment Station, and Asia Foundation for their financial assistance to pursue graduate work at the University of Hawaii, and to Kodama Nursery for donation of some plant materials. ABSTRACT Phalaenopsis was clonally propagated by use of in vivo and _in vitro methods. In vivo, plantlets formed naturally on the node and tip of inflorescence, or root. Application of N-6-benzyl adenine to exposed buds on the inflorescence spike to induce plantlet formation was not very successful. Rapid clonal propagation was successfully accomplished by use of in vitro culture techniques. Explants from the nodal buds of inflorescence were the most suitable material for culture, although apical and axillary buds from the stem could also be used. When basal nodes from inflorescences after flowering or young inflorescences were cultured in basal media (BM = Vacin and Went 4- 15% coconut water), one to four plantlets rather than protocorm-like bodies (plbs) were obtained from a single node. -

In Vitro Germination, Protocorm Formation, and Plantlet Development of Orchis Coriophora (Orchidaceae), a Naturally Growing Orchid Species in Turkey
Turkish Journal of Botany Turk J Bot (2013) 37: 336-342 http://journals.tubitak.gov.tr/botany/ © TÜBİTAK Research Article doi:10.3906/bot-1205-28 In vitro germination, protocorm formation, and plantlet development of Orchis coriophora (Orchidaceae), a naturally growing orchid species in Turkey Ersan BEKTAŞ*, Mustafa CÜCE, Atalay SÖKMEN Department of Biology, Faculty of Sciences, Karadeniz Technical University, 61080 Trabzon, Turkey Received: 23.05.2012 Accepted: 22.11.2012 Published Online: 15.03.2013 Printed: 15.04.2013 Abstract: Some species belonging to the genus Orchis Tourn. ex L. (Orchidaceae) are of great economic importance as their tubers or corms are used to produce a hot beverage called salep. Nevertheless, these plants are not cultivated but are rather collected from nature, and due to careless collection many have already been listed as endangered plants. In order to assess the possibility of in vitro propagation, an orchid, Orchis coriophora L., was selected as a model plant, and the effects of basal media and plant growth regulators on in vitro seed germination, protocorm development, and plantlet formation were studied. Mature seeds were cultured in 4 different basal media, each supplemented with various concentrations and/or combinations of auxins and cytokinins/cytokinin-like substances. The highest germination rate (44.2%) was observed in Orchimax medium including activated charcoal plus 1 mg/L indole-3-acetic acid. Protocorms developed plantlets in all the tested media. Orchimax medium including activated charcoal and supplemented with 0.25 mg/L 6-benzyladenine was found to be the most suitable medium for the formation of plantlets from protocorms. -

Ir. Sutami no 36A, Surakarta 57126, Indonesia Received : 5 August 2009 Accepted: 27 August 2009 Abstract To study the intergeneric crossing between orchids of Phalaenopsis sp. and Vanda tricolor, three species of Phalaenopsis sp. (Phalaenopsis Joane Kileup June, Phalaenopsis Pinlong Cinderella, and (Phal. Fortune Buddha x Phal. Princess Kaiulani) were crossed reciprocally with Vanda tricolor in time-different value (within the first, second and third week after full opened flower). The crossing of Phalaenopsis sp. and Vanda tricolor was compatible, and the use of Phalaenopsis sp. as male parent had better probability in producing fruits rather than the opposite. The crossing which was done at the first and the second weeks after blooming produced more fruit than the crossing at the third week after blooming, even though it did not affect the success of crossing, time of fruit formation, and duration of fruit hanging. Key words: Intergeneric Crossing, Orchids, Phalaenopsis sp., Vanda tricolor INTRODUCTION One strategy to make a new-hybrid compatible to Doritis pulcherrima var. cultivars of orchids is by crossing between the Champornensis (Hartati, unpublished results). orchid-parents having different characters. To assess the effect of time of crossing (week Orchid hobbyist usually prever to collect after blooming) in order to make new hybrid hybrid resulted from crossing orchids, orchids with more attractive flower characters because the hybrided orchids have more to the fruit formation in, Phalaenopsis sp. -
Crippling American Cattleyas–
Crippling A Genetic issue in Yellow and Art-Shade Cattleyas And an update of primary hybrids associated with American Cattleyas – Species and Outstanding Clones that Defined American Hybridizing Emphasis on Primary Grexes In the June 2010 issue of Orchids, Ron Midgett discussed the little mention (but well known) issue of crippling, a genetic problem, in yellow and art-shade Cattleyas. It was the bane of efforts to breed good nonfading yellow cattleyas because the parents with the best color crippled. Crippling, which caused a thickening of tissue in the petal, became worse with age (the older the plant, the worse the crippling). It would start as a slightly thickened line of tissue running more or less parallel to the long axis of the petal. It is thought that this tissue was an attempt to create another stamen because in the worst cases a knob of tissue would form at the distal end of the thickened tissue. Inside this knob, one could usually find poorly formed but unmistakable pollinia. In the two pictures of Rhyncholaeliocattleya Golden Queen ‘Regina’ (Golden Crown x C. Miguelito), one shows a flower without crippling and the second, taken at a later blooming, show's severe crippling. This disfigurement of the flower was disheartening. Crippling is a genetic problem and continues in future bloomings, it is NOT sporadic (such as cultural related deformities). C. dowiana ‘Amanda Sofia’ AM/AOS It is generally Apr 2016, NS 11.5 x 16.2 cm accepted that the crippling gene came from the use of a particular clone of Cattleya dowiana (hort. -
Phytogeographical Analysis and Ecological Factors of the Distribution of Orchidaceae Taxa in the Western Carpathians (Local Study)
plants Article Phytogeographical Analysis and Ecological Factors of the Distribution of Orchidaceae Taxa in the Western Carpathians (Local study) Lukáš Wittlinger and Lucia Petrikoviˇcová * Department of Geography and Regional Development, Faculty of Natural Sciences, Constantine the Philosopher University in Nitra, 94974 Nitra, Slovakia; [email protected] * Correspondence: [email protected]; Tel.: +421-907-3441-04 Abstract: In the years 2018–2020, we carried out large-scale mapping in the Western Carpathians with a focus on determining the biodiversity of taxa of the family Orchidaceae using field biogeographical research. We evaluated the research using phytogeographic analysis with an emphasis on selected ecological environmental factors (substrate: ecological land unit value, soil reaction (pH), terrain: slope (◦), flow and hydrogeological productivity (m2.s−1) and average annual amounts of global radiation (kWh.m–2). A total of 19 species were found in the area, of which the majority were Cephalenthera longifolia, Cephalenthera damasonium and Anacamptis morio. Rare findings included Epipactis muelleri, Epipactis leptochila and Limodorum abortivum. We determined the ecological demands of the abiotic environment of individual species by means of a functional analysis of communities. The research confirmed that most of the orchids that were studied occurred in acidified, calcified and basophil locations. From the location of the distribution of individual populations, it is clear that they are generally arranged compactly and occasionally scattered, which results in ecological and environmental diversity. During the research, we identified 129 localities with the occurrence of Citation: Wittlinger, L.; Petrikoviˇcová, L. Phytogeographical Analysis and 19 species and subspecies of orchids. We identify the main factors that threaten them and propose Ecological Factors of the Distribution specific measures to protect vulnerable populations. -
Nomenclature
NOMENCLATURE The written language of Horticulture The Written Language of Horticulture To write the names of orchids correctly we must understand the differences between species and hybrids, know the abbreviations for the various species and hybrids and follow a few simple rules The Written Language of Horticulture 1. A species orchid occurs naturally in nature. Plants of the same species sometime vary in shape and colour. These are called varieties and given a special varietal name. 2. A hybrid is a cross between species or hybrids or a species and a hybrid. (A Primary hybrid is a cross between two species.) (A Natural hybrid is a cross that occurs naturally in nature.) The Written Language of Horticulture As an example we will look at the cattleya family species abbreviation Brassavola B. Cattleya C. Laelia L. Sophronitis Soph. Broughtonia Bro. The Written Language of Horticulture When a Cattleya is crossed with a Brassavola it becomes a Brassocattleya, abbreviated Bc. When a Cattleya and Laelia are crossed it becomes a Laeliocattleya, abbreviated Lc. When a Brassocattleya is crossed with a Laelia it becomes a Brassolaeliocattleya, abbreviated Blc. When a Brassolaeliocattleya is crossed with a Sophronitis it becomes a Potinara, abbreviated Pot. When a Broughtonia is crossed with a Cattleya it becomes a Cattletonia, abbreviated Ctna. The Written Language of Horticulture Why make these crosses 1. The Brassavola imparts large frilly labellums to the cross. 2. The Sophronitis imparts yellow, red, orange to the flowers. 3. The Broughtonia imparts dwarf structure, miniature clusters, good shape and flowers several times per year LET US NOW LOOK AT HOW TO WRITE THE NAMES OF ORCHIDS The following are a few rules that will assist in writing orchid names. -
Phalaenopsis
Chapter 23 Phalaenopsis Chia-Chi Hsu, Hong-Hwa Chen, and Wen-Huei Chen Abstract Phalaenopsis is one of the most popular cultivated orchids worldwide. So far, 92 native species and 34,112 hybrids of Phalaenopsis have been registered in the Royal Horticultural Society (RHS), but only 18 native species are frequently used for breeding. In Phalaenopsis market, large flowers with various colors are most popular. Phal. amabilis and Phal. aphrodite are the major species used for breeding the white-and-large-flower hybrids. The colored hybrids include pink, red- to- purple, green, yellow-to-orange, and black colors, as well as distinct colors in tepals with red lip. For large-and-red flowers,Phal. schilleriana and Phal. sanderiana are the major parent species, whereas Phal. equestris and Phal. pulcherrima are important for the development of the small- and medium-sized red flowers. Members of the subgenusPolychilos are the most important ancestors for yellow-to-orange flowers. More recently, there is an increased interest in plants with white, pink, or yellow colors with red stripes and/or spots. These traits are introduced from Phal. lindenii, Phal. stuartiana, and Phal. amboinensis. Furthermore, harlequin flowers which have clown-like spots and very complicated color patterns are released in the market, as well as hybrids with peloric and Bigfoot flowers. Besides color, scent and (a)biotic stress resistance are becoming important targets in Phalaenopsis breeding. Keywords Bigfoot · Breeding · Harlequin · Orchids · Peloric · Phalaenopsis C.-C.
