Orchid Biology Viii

This is the eighth volume in a 25-year-old series that has become the cornerstone review publication of orchid science. It presents authoritative reviews on different areas of orchid science and historical accounts by major orchid authorities, providing information for botanists, orchid scientists, and growers.

As stated many times before the purpose of Orchid Biology, Reviews and Perspectives (OB) is to present reviews on all aspects of orchids. The aim is not to balance every volume, but to make a balanced and wide ranging presentation of orchids in the series as a whole. The chapters in this, the last volume of the series, range over a number of topics which were not covered before. Singapore is justly famed for its orchids. They can be seen on arrival (or dep- ture) in its modern, highly efficient and comfortable Changi Airport and on the way from it to town. Vanda Miss Joaquim, the first hybrid to come from Singapore became its National Flower. This natural hybrid can be seen on its currency, stamps, and public and private decorations. Many excellent breeders, starting with Prof. Eric Holttum who bred the first man made hybrid (Spathoglottis Primrose), produced numerous magnificent hybrids and won countless awards in Singapore and elsewhere. These hybrids served to enrich the country’s orchid mystique. In the opening chapter of this volume Dr. Teoh Eng Soon (Western style: Eng Soon Teoh), himself a prize winning orchid breeder, grower and author writes about some of the breeders who contributed to the Singapore orchid fame. Prof. Hans Fitting was one of the best known plant physiologists of his time. As a young man he studied the effects of pollen on orchid flowers.

Examines the biology, history, evolution and commercial uses of orchids. All aspects of the orchid are explored including how they are classified and named; the cytology, physiology, phytochemistry and morphology of orchids; their anatomy, mycorrhiza, pollination, embryology, reproduction, heredity and breeding and ecological characteristics. Numerous illustrations throughout aid in comprehension.

Orchid Biology: Reviews and Perspectives, IX, (2007) presents a broad range of scientific subjects that represents the most current knowledge in orchidology. This volume includes chapters that discuss (1) Calaway Dodson, whose research on the orchids of Ecuador continues to inspire generations of botanists; (2) orchids pollinated by Lepidoptera; (3) a comprehensive survey of terrestrial orchid morphology; (4) the original writings (translated into English) on orchid seed germination by Noël Bernard; (5) the origin of Singapore's national flower, the well-known orchid Vanda 'Miss Joaquim'; (6) a thorough overview of the impact that DNA sequence data has made in orchid systematics by focusing on the first decade of contributions in molecular phylogenetic studies of Orchidaceae; and (7) a detailed appendix, the subject of which is species-by-species records from pollination to fruit ripening, seed maturation, and germination of orchids. Volume IX of Orchid Biology: Reviews and Perspectives is truly international in scope and diverse in subject. 10th volume (2009) in a series which was initiated in 1977. Like previous volumes, it contains scientific peer reviewed reviews on topics dealing with orchids. These topics include 1) a history of orchid breeders in Singapore, 2) discussion of research on pollen effects on orchid flowers carried out a century ago by the German plant physiologist Hans Fitting in Bogor, Indonesia which led to the first suggestion that plants produce hormones, 3) consideration whether orchids are mentioned in the Bible, 4) review of food hairs in orchids, 5) outline of pollen dispersal units in orchids, 6) survey of orchids in art, 7) a tracing of the history of Vanilla pollination, 8) a chapter on viruses which attack orchids and 9) an appendix which lists a very large number of orchid books. All the volumes in this series will appeal to those who are interested in orchids and plant scientists in general.

This book on “Orchid Biology: Recent Trends & Challenges” reviews the latest strategies for the preservation and conservation of orchid diversity and orchid germplasm. It is an outcome of the Proceedings of the International Symposium on “Biodiversity of Medicinal Plants & Orchids: Emerging Trends and Challenges” held on 9-11 February 2018 at Acharya Nagarjuna University, India. In addition, eminent orchid experts from around the globe were invited to contribute to this book. All chapters were peer-reviewed by international experts. The Orchidaceae are one of the largest families of flowering plants, comprising over 700 genera and 22,500 species and contributing roughly 40 percent of monocotyledons. They also represent the second-largest flowering plant family in India, with 1,141 species in 166 genera, and contribute roughly 10% of Indian flora. Orchids comprise a unique group of plants and their flowers are among the most enchanting and exquisite creations of nature. Phylogenetically and taxonomically, the Orchidaceae are considered to be a highly evolved family among angiosperms. They show incredible diversity in terms of the shape, size and colour of their flowers, and are of great commercial importance in floriculture markets around the globe. Millions of cut flowers of Cymbidium, Dendrobium, Cattleya, Paphiopedilum, Phalaenopsis, Vanda etc., besides potted orchid plants, are sold in Western Countries and thus, the orchid cut flower industry has now become a multimillion-dollar business in Europe, the USA and South East Asia. Besides their ornamental value, orchids hold tremendous pharmaceutical potential. Root tubers of Habenaria edgeworthii form an important component of the ‘Astavarga’ group of drugs in Ayurvedic medicine. It is an established fact that tubers of some terrestrial orchids have been used to treat diarrhoea, dysentery, intestinal disorders, cough, cold and tuberculosis. Some orchids, particularly those belonging to the genera Aerides, Arachnis, Cattleya, Cymbidium, Dendrobium, Epidendrum, Oncidium, Paphiopedilum, Phalaenopsis, Renanthera, Vanda etc. have been extensively used to produce internationally acclaimed hybrids. Yet paradoxically, Indian orchids are victims of their own beauty and popularity. As a result, their natural populations have been declining rapidly because of unbridled commercial exploitation in India and abroad. In fact, some orchids are now at the verge of extinction, e.g. Renanthera imschootiana, Diplomeris hirsuta, Paphiopedilum fairrieanum, Cypripedium elegans, Taeniophylum andamanicum etc. Given the global importance of orchids in terms of securing human health and wealth, this comprehensive compilation, prepared by international experts, is highly topical. Its content is divided into five main sections: (I) Cryopreservation & Biotechnology, (II) Orchid Biodiversity & Conservation, (III) Anatomy & Physiology, (IV) Pollination Biology and (V) Orchid Chemicals & Bioactive Compounds. All contributions were written by eminent orchid experts/professors from around the world, making the book a valuable reference guide for all researchers, teachers, orchid enthusiasts, orchid growers and students of biotechnology, botany, pharmaceutical sciences and ethnomedicine. It will be equally valuable for readers from the horticultural industry, especially the orchid industry, agricultural scientists and policymakers.

Recent studies have revealed remarkable complexity and diversity in orchid-pollinator relationships. These studies comprise a vast literature currently scattered in numerous, often obscure, journals and books. The Pollination Biology of North American Orchids brings together, for the first time, a comprehensive treatment of this information for all native and introduced North American orchids found north of Mexico and Florida. It provides detailed information on genetic compatibility, breeding systems, pollinators, pollination mechanisms, fruiting success, and limiting factors for each species. Distribution, habitat, and floral morphology are also summarized. In addition, detailed line drawings emphasize orchid reproductive organs and their adaptation to known pollinators. This, the first of two volumes, furnishes a brief introduction to the general morphology of the orchid flower and the terminology used to describe orchid breeding systems and reproductive strategies. It treats the lady’s-slippers of genus Cypripedium, subfamily Cypripedioideae, and nine genera of the subfamily Orchidoideae, including the diverse rein orchids of genus Platanthera. The Pollination Biology of North American Orchids will be of interest to both regional and international audiences including: Researchers and students in this field of study who are currently required to search through the scattered literature to obtain the information gathered here. Researchers and students in related fields with an interest in the co-evolution of plants and insects. Conservation specialists who need to understand both the details of orchid reproduction and the identity of primary pollinators in order to properly manage the land for both. Orchid breeders who require accurate and current information on orchid breeding systems. General readers with an interest in orchid biology. Charles Argue, Ph.D., is a plant biologist at the University of Minnesota specializing in the study of pollen grains. His articles have appeared in numerous journals including the American Journal of Botany, International Journal of Plant Sciences (formerly Botanical Gazette), Botany (formerly Canadian Journal of Botany), Grana, Pollen et Spores, North American Native Orchid Journal, The Native Orchid Conference Journal, Fremontia, and as chapters in a number of books.

Over the past ten years, the orchid industry has been growing at a steady pace in South-East Asia and East Asia. In some Asian countries, orchids have become an essential export item. To maintain this progress, there is an urgent need for a book that will help the region's orchid growers in improving their cultivation and management skills, and guide new students in understanding orchid physiology. This book provides a comprehensive description of tropical orchid physiology relevant to commercial growers, research workers and graduate students. An integrated and unifying theme of tropical orchid physiology, with a clearly written factual text as well as illustrations, is presented over nine chapters. Each chapter is designed to provide comprehensive and up-to-date information on a particular aspect of orchid physiology. This book complements the existing scientific literature available for improving orchid cultivation and setting a new research agenda, especially in the tropics.
