Download or read book Orchid Biology Recent Trends Challenges written by Shaik Mahammad Khasim and published by Springer Nature. This book was released on 2020-01-31 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This action plan chronicles the threats faced by wild orchids, but more importantly to critical habitats that host extraordinarily high orchid diversity and endemicity. It explores and recommends specific ways that national and local government, legislators, scientists and orchid conservationists as well as growers can all help to reverse present trends. The facts and viewpoints presented in this comprehensive document update and supplement the information available to conservation organizations and agencies through the world so that they can lobby their appropriate government offices more effectively.

This book was released on 2009-01-21 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.
