Dendrobium orchids have been among Hawaii's most popular plants since Dendrobium anosmum, with its hanging pseudobulbs and delightfully fragrant flowers, was introduced from the Philippines in 1896. Four decades later the Islands' first Dendrobium hybrid was registered, and by the 1950s, coinciding with the advent of the University of Hawai'i's orchid research program, Hawaii was established as the center for Dendrobium hybridization. Dendrobiums have since become the single most valuable commercial flower in Hawaii, given their combined use for cut-flowers, leis, and blooming potted plants. Breeding Dendrobium Orchids in Hawaii summarizes for easy reference research on cytogenetics and breeding of dendrobiums conducted over the past 47 years, mainly at the University of Hawai'i. A lavishly illustrated section on species important to Hawaii's orchid industry is followed by a description of the origin of many popular hybrids. Throughout, information on cross-breeding, seed propagation, flower color and form, and controlling disease is presented in language readily understood by the layperson. A total of 175 color photographs showcase registered hybrids, cut-flower cultivars, potted plant cultivars, and novelties. The authors share valuable tips on counting Dendrobium orchid chromosomes, germinating seeds, and cloning plants and provide a comprehensive glossary. Breeding Dendrobium Orchids in Hawaii will be an essential reference for anyone associated with orchids-growers, hobbyists, breeders, tissue culture propagators, plant geneticists, and horticultural scientists.
Orchid Biotechnology IV presents a series of recent work on both basic and applied researches in biotechnology progress for Phalaenopsis, Oncidium and Erycina pusila orchids. These include breeding of Phalaenopsis orchids of black flower, big-white flower and small and floriferous flowers, physiology for shipping and photosynthesis, SSR markers and mitochondrial DNA markers, virus detection and antiviral immunity, embyogenesis and relationship with mycorrhiza symbiosis, transposon and retrotransposon, orchid genome and evolution, regulation of orchid floral scent, floral color modification, and abiotic stress tolerance.The diversity and specialization in orchid floral morphology have fascinated botanists and collectors for centuries. The orchid industry has been growing substantially worldwide. To advance the orchid industry, enhancement of basic research as well as advanced biotechnology will provide a good platform to improve the flower quality and the breeding of new varieties. This book provides a first-hand and up-to-date information on orchid breeding, orchid genome evolution, detection of virus in nanotechnology, molecular markers for cultivar identification for orchid lovers, researchers and industry growers.
This book provides comprehensive insights into the existing and emerging trends in orchid biology based on the findings of omics, high-throughput technology, biotechnology, molecular breeding, and genome editing approaches in orchids. It illustrates molecular mechanisms of orchid mycorrhizal symbiosis according to the recent achievements of transcriptomics and bioinformatics studies which accelerate the progress of orchid research with the aid of their high-throughput tools. In this book, a comprehensive view of orchid breeding was presented, and it includes fundamental methods as well as advanced strategies through the combination of several technologies such as genetic engineering, omics, computational biology, and genome editing. These resulting knowledge and tools are highly beneficial for obtaining novel and fascinating varieties in the orchid market which is a competitive industry of global trade. Another interesting content is the focus on the production of orchid bioactive compounds and their values in the field of ethnomedicine. Their sources chiefly came from secondary metabolites and can be enriched through elicitors and produced more efficiently by improved tissue culture protocols and bioreactors. In this edited collection, we provided space for presenting an updated review of in vitro seed germination which is a routine technology for well-trained researchers but can give a complete demonstration for the potential audiences including growers and research beginners. This book collects refined knowledge from a broad source of scientific literature by experts in the field of orchid research and surely is an adequate reference and textbook for students, teachers, and researchers. It includes methods and applications of orchid breeding technology which would gain high attention from growers, breeders, and the related fields of agriculture.
