Download or read book Betula written by Carl T. Bertelsen and published by . This book was released on 2020-04-24 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genus Betula, generally known as birch, belongs to the family Betulaceae. There are about 83 recognized species of Betula, all of which are essential ecological components of northern temperate and boreal woodlands in many parts of the world. The species of this genus have a good tolerance to freezing temperature and water deficit, as well as high sensitivity to UV-B exposure. The chemical composition of Betula pubescens Ehrh. and Betula pendula Roth. buds is assessed, providing data on their biological activities. Betula species show antiarthritic, anticancer, antidiabetic, anti-inflammatory, antimicrobial, antioxidant, antiviral, gastroprotective, hepatoprotective and immunomodulatory activities, and the authors propose that it is important to consider the biopharmaceutical properties of the secondary metabolites for further development.

Book Synopsis The Genus Lachenalia by : Graham Duncan
Download or read book The Genus Lachenalia written by Graham Duncan and published by Royal Botanic Gardens Kew. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first complete and illustrated monograph of the genus Lachenalia, a horticulturally important and botanically diverse plant group. Lachenalia ranks with Gladiolus as one of the two most popular genera of South African bulbous plants worldwide, and next to Ornithogalum is the second-largest member of the family Hyacinthaceae in southern Africa.The flowers of some species have exceptionally showy blooms that occur in numerous interesting colours, shapes and sizes, and their fascinating leaves, many of which are attractively spotted or barred, or covered with attractive hairs or pustules. The flowers of many species are attractive in another dimension in that they emit distinctive aromas, ranging from spicy (like cloves) to various degrees of sweet (like a mixture of carnations and orchids), while one species is strongly coconut-scented.All species are described, classified and illustrated, with detailed text on history, morphology, phylogeny, phytogeography, pollination biology, cultivation and propagation. This book includes many highly attractive species which have never been illustrated in colour before, with 11 new taxa, ten of which are new species.This will become the standard reference work on all aspects of the genus and will appeal to botanists and taxonomists, bulb-growers, horticulturalists, gardeners, collectors of fine botanical works, ecologists and nature conservationists, as well as libraries and universities.

Download or read book The Rhizosphere written by Zoe G. Cardon and published by Elsevier. This book was released on 2011-04-28 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Below the soil surface, the rhizosphere is the dynamic interface among plant roots, soil microbes and fauna, and the soil itself, where biological as well as physico-chemical properties differ radically from those of bulk soil. The Rhizosphere is the first ecologically-focused book that explicitly establishes the links from extraordinarily small-scale processes in the rhizosphere to larger-scale belowground patterns and processes. This book includes chapters that emphasize the effects of rhizosphere biology on long-term soil development, agro-ecosystem management and responses of ecosystems to global change. Overall, the volume seeks to spur development of cross-scale links for understanding belowground function in varied natural and managed ecosystems. First cross-scale ecologically-focused integration of information at the frontier of root, microbial, and soil faunal biology Establishes the links from extraordinarily small-scale processes in the rhizosphere to larger-scale belowground patterns and processes Includes valuable information on ecosystem response to increased atmospheric carbon dioxide and enhanced global nitrogen deposition Chapters written by a variety of experts, including soil scientists, microbial and soil faunal ecologists, and plant biologists

Download or read book Trees II written by Y. P. S. Bajaj and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'frees contribute a major part of fuel, fodder and fruit, and are an im of bioenergy. They are now needed in large numbers more portant source than ever before for afforestation and social forestry, so that fast-grow ing and multipurpose trees assume great importance. After extensive in discriminate deforestation and rapid depletion of genetic stocks, efforts are now being made to evolve methods for clonal mass propagation of improved and elite trees. Production of short-duration trees with a rapid turnover of biomass, and induction of genetic variability through in vitro manipulation for the production of novel fruit and forest trees, which are high-yielding and resistant to pests and diseases, and trees which display increased photosynthetic efficiency are in demand. These objectives are well within the realm of horticultural and forest biotech nology. Some of the recent advances, such as the regeneration of com plete trees from isolated protoplasts, somatic hybridization, and the Agrobacterium-mediated transformation in various tree species have opened new vistas for the genetic engineering of fruit and forest trees. This book is a continuation of the earlier volume Trees I, and presents 31 chapters on fruit, forest, nut and ornamental trees, such as avocado, pineapple, crabapple, quince, pistachio, walnut, hazelnut, date palm, oil palm, cacao, rubber, maple, sweet-gum, poplars, birches, Chinese tallow, willows, oaks, paper mulberry, rhododendrons, Scots pine, Calabrian pine, Douglas-fir, redwood, ginkgo, cycads and some flowering trees.

Book Synopsis A Taxonomic Study of Western Canadian Species in the Genus Betula by : Janet Rogge Dugle
Download or read book A Taxonomic Study of Western Canadian Species in the Genus Betula written by Janet Rogge Dugle and published by . This book was released on 1964 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five western North American birches, Betula fontinalis . B. glandulosa , B. pumila var. glandulifera , B. resinifera and B. papyrifera are studied taxonomically. Synonymy, descriptions, distribution and representative specimens examined are included. Four hybrid taxa, B. x winteri , B. x sargentii , B. x arbuscula, and B. x uliginosa , are described for the first time and three additional hybrids, B>. x utahensis , B. x eastwoodae and B. x sandbergii are also included. When birch species are in contact, they often hybridize. The populations so formed have been analyzed and the nature of several hybrid entities determined. The methods of analysis applied are as follows: chromatography of leaves and bark; hybrid index; polygonal graphs; chromosome numbers; pollen size, morphology and stainability; stomatal size; germination data; and pictorialized scatter diagrams. Betula x uliginosa (2n = 28-56) is the result of hybridization between B. resinifera and B. pumila var. glandulifera . In the population analyzed, introgression was in the direction of B. pumila var. glandulifera , the birch with the higher chromosome number. When B. pumila var. glandulifera is in contact with B. glandulosa , B. x sargentii (2n = 28-56) is produced. Introgression seems to be in both directions, although most of the gene flow is in the direction of the taxon with the higher chromosome number, B. pumila var. glandulifera . B. x eastwoodae (2n = 28) is the result of hybridization between B. glandulosa and B. fontinalis . Introgression was influenced very little by environmental selection, and B. x eastwoodae seemed to be as common as either of the parental species; and any gene flow was in either direction. B. x utahensis (2n = 28-84 with a concentration at 2n = 56) is the result of hybridization between B. papyrifera and B. fontinalis . In populations of these birches, introgression is mainly from B. fontinalis into B. papyrifera . Hybridization of B. x sargentii and B. papyrifera results in B. x arbuscula (2n = 28-84), a rare hybrid. Tentative conclusions are that introgression is in the direction of B. papyrifera , the taxon with the higher chromosome number. Hybridization of B, resinifera and B. papyrifera produces B. x winteri (2n = 28-84 with a concentration of individuals at 2n = 56). In the populations of these birches which were analyzed, introgression was in both directions. B. x sandbergii (2n = 56-84) results from hybridization of B. papyrifera and B. pumila var. glandulifera . As contrasted with the above, and probably as a result of strong environmental influence in the area in which this cross was analyzed, introgression was in the direction of J3. pumila var. glandulifera , the parental taxon with the lower chromosome number.
