There Background/Question/Methods One of the challenges of invasive species biology goes the neighborhood: Reproductive success of is knowing whether or not a naturalized species is invasive before dramatic Bletia patula when Spathoglottis plicata moves ecosystem changes occur. In Puerto Rico, the exotic orchid, Spathoglottis plicata, in. PS 66-14: The 95th ESA Annual Meeting, has naturalized and spread rapidly over the last two decades. It is abundant and August 1-6, 2010. ESA, Pittsburg occupies the same habitat as the native orchid, Bletia patula. The two are hosts to the same native florivorous weevil, Stethobaris polita, a specialist on orchid flowers. We ask whether high population densities of Spathoglottis plicata affect the reproductive success of Bletia patula by elevating the abundance of the weevil. We measured local densities of the orchids where the two species grow together and also where B. patula grows in absence of S. plicata. We measured female reproductive success of Bletia at all sites. We also monitored the abundance of weevils and the extent of floral damage they cause on Bletia patula. In addition, we experimentally tested in vitro whether weevils preferred one species to the other. Finally, we modeled the distribution of both orchid species to predict the extent to which the two species may interact. Results/Conclusions Preliminary data indicate the number of weevils per Bletia inflorescence tends to be higher where S. plicata is also present. These data also show a significantly higher flower and fruit production for B. patula where S. plicata is absent. The weevil choice experiments show that the beetles do not prefer flowers of one species to the other. The current distribution of the native Bletia patula is almost completely limited to the northern karst region of Puerto Rico whereas the naturalized S. plicata has established in nearly all moist to wet habitats of the island with a high frequency of populations in the same region as B. patula. The Spathoglottis is expected to occur wherever B. patula exists. Our data thus far suggest that Spathoglottis plicata is an invasive species. It negatively affects the reproductive success of the native orchid, Bletia patula, through an elevation in the frequency and abundance of the florivorous weevil."

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.

Freudenstein, Adviser Dr. John Wenzel ________________________________ Dr. Andrea Wolfe Adviser Evolution, Ecology and Organismal Biology Graduate Program COPYRIGHT ERIK PAUL ROTHACKER 2007 ABSTRACT Considering the significance of the basal Epidendroideae in understanding patterns of morphological evolution within the subfamily, it is surprising that no fully resolved hypothesis of historical relationships has been presented for these orchids. This is the first study to improve both taxon and character sampling. The phylogenetic study of the basal Epidendroideae consisted of two components, molecular and morphological. A molecular phylogeny using three loci representing each of the plant genomes including gap characters is presented for the basal Epidendroideae. Here we find Neottieae sister to Palmorchis at the base of the Epidendroideae, followed by Triphoreae. Tropidieae and Sobralieae form a clade, however the relationship between these, Nervilieae and the advanced Epidendroids has not been resolved. A morphological matrix of 40 taxa and 30 characters was constructed and a phylogenetic analysis was performed. The results support many of the traditional views of tribal composition, but do not fully resolve relationships among many of the tribes. A robust hypothesis of relationships is presented based on the results of a total evidence analysis using three molecular loci, gap characters and morphology. Palmorchis is placed at the base of the tree, sister to Neottieae, followed successively by Triphoreae sister to Epipogium, then Sobralieae.

  • Do Orchids Grow in Hawaii? and How!
    Do Orchids Grow in Hawaii? And How! SYNOPSIS This is an historical sketch of the Saga of Orchids in Hawaii. The sequence of events from the incidental introduction of species by the Agriculturists for the Sugar Industry; to their efforts in propagation and culture, hybridizing and germination; to the development of personal nurseries to commercial ranges; and ultimately to the creation of a viable orchid industry, re­ cognized world wide; to the natural formation of orchid societies staging of orchid shows; and finally to the introduction of a system of orchid judging , should bring interesting reading to orchidists, amateur and professional alike. In fact, this could serve as a reference syllabus to keep. DO ORCHIDS GROW IM HAWAII? AMD HOW i Compiled and Edited by Dr. T. David Woo and Wallace K.

DISSERTATION COMMITTEE (7 'Cry^o , w A Chairman Chromosome Numbers and Cross-Compatibility in the Genus Cymbidium and Some Related Tropical Genera (Orchidaceae) Abstract Investigations on chromosome numbers and cross-compatibility were made with species and hybrids of Cymbidium and other tropical genera of the family Orchidaceae. Chromosome number determinations were made of 163 plants. One hundred nineteen counts of Cymbidium clones were made of which 92 are reported for the first time. Diploid, triploid, tetraploid, hexaploid and aneuploid individuals were determined. Triploid cultivars of two species, C. insigne 'Bierii' and C. pumilum 'Yashima' were found. Forty- four counts of intergeneric hybrids and genera other than Cymbidium were made. The hybrid status of 17 progenies of intergeneric pollinations was determined by analysis of somatic chromosome numbers. Nine plants derived from colchicine treated protocorms were identified as polyploids; 8 being euploid and 1 a mixoploid. The origin of the polyploid nature of some of the hybrids not subjected to colchicine treatments is dis­ cussed. It was verified cytologically that Cymbidium did hybridize with Ansellia and Catasetum.

Introduction Acanthephippium is a genus of eleven species distributedin Southeast Asia from Sri Lanka to Nepal and north to Japan, all over the Malesian Archipelago and in many islands in the Pacific. The genus was established by Blume in 1825 with one species, Acanthephippium javanicum. The generic name is derived from two Greek roots: acantha (thorn) and ephippion (sad- dle), the former referring to the long slender column, and the latter to the saddle-shaped lip. Blume (1825) first published the generic name as Acanthophippium, an orthographi- his cal error which he corrected in the preface of Flora Javae (1828). The older spelling authors. I have followed who stated: "Since was followed by several Sprague (1928) the spelling Acanthophippium contains a definite (and apparently unintentional) orthographic the of the initial letter of and the alteration error, namely missing ephippium (a saddle) to Acanthephippium involves no risk of confusion or error, the latter spelling should be adopted." The plants are pseudobulbous terrestrials, with large plicate leaves. The inflorescence is lateral from the new year's growth, and much shorter than the leaves so that the flowers are mostly displayed low downon the plant. The flowers are large and fleshy, usually 3-4 lesser fused into cm long.
