The Biology and Utilization of Shrubs by Cyrus McKell Pdf

The Biology and Utilization of Shrubs brings together the wide range of information about shrubs from many disciplines and world locations. The book is organized into seven parts. Part I describes the major shrublands found on each of the vegetated continents. It provides an overview of the dominant shrubland types as well as the associated features of soil and climate that influence the geographic distribution of major shrub species. Part II discusses environmental influences and plant responses. Part III considers the range of genetic diversity for important traits and how these may vary in different habitats. Part IV discusses the effects of stress on physiological processes of shrubs, and the kinds of strategies shrubs employ to meet physiological stress. Part V offers evidence to support the claim that the many virtues of shrubs provide a basis for sustaining shrub use for livestock fodder, wildlife habitat, reclamation and erosion control, fuel, and naturalized landscaping. Part VI outlines methods for collecting and processing seeds from natural stands or from superior genotypes planted in seed production orchards. Part VII describes cultural adaptation to shrub use in a livestock-dominated primitive culture, followed by a detailed economic analysis of establishing shrub plantations to improve livestock production.

Scope of the study The degradation of renewable natural resources in the arid areas of South West Asia has become a matter of great concern. Locally the effects of careless utili zation of the land and its resources had been felt long ago. It is, however, only relatively recently that the gravity of the situation is being generally and fully realised. It is now well understood that action is required to save what is left and possibly to restore what was once there. Such action requires organization and coordination, but above all knowledge of the present state of the resources and the impact of utilization processes. Part of this knowledge is already available. The problems are not confined to this part of the world's arid lands, but exist equally well elsewhere. Especially over the last decades an ever increasing number of studies have been published dealing with aspects of arid zone research. Problem analyses were followed by compila tions of knowledge in particular fields (White 1956; Hills 1966; Mc Ginnies et al. 1967, 1969, 1971;KauI1970;Clawsonetal.

APPLIED BIOLOGY OF WOODY PLANTS by Ratikanta Maiti,Humberto González Rodríguez,Ch. Aruna Kumari Pdf

Woody plants occupy dominant vegetation in forest ecosystem. They play an important role in reducing carbon load from the atmosphere and store them as biomass and carbon as sources of energy. Forest trees are sources of timbers, various domestic uses, medicinal purposes, forest products, and sources of animal nutrition. At this juncture, there is a great necessity to save forest trees for life security and effective management and maintain an ecobalance to save earth from the clutch of pollution. To fulfill these objectives, a clear understanding of the biology of trees and its applications is an essential prerequisite for effective management and its application. No such book is available to undergraduate and graduate students and teachers. It discusses experimental biology to study the various aspects of tree biology from a practical stand point guide. This deals with general concepts of plant, soil and environments, the vegetation and biodiversity, morpho-anatomical and ecophysiological traits phenological events and plasticity, branching pattern and branching density functioning as solar panel for capture of solar radiation for productivity, diversity of leaves morphological and biochemical traits such as pigments, epicuticular wax, leaf macronutrients necessary for the growth and development and animal nutrition, wood anatomical traits related to timber quality and utility. A special emphasis has been given in the selection of tree species with high ecophysiological traits. The book deals with advances in research and includes our original research results.

Halophytes as a resource for livestock and for rehabilitation of degraded lands by V. Squires,A.T. Ayoub Pdf

Desertification (land degradation in arid, semi-arid and dry sub-humid areas resulting mainly from adverse human impacts) is the main environmental problem of dry lands, which occupy more than 40 per cent of the total global land area. The phenomenon threatens about 3.6 billion hectares and currently affects the livelihood of about 900 million people. Thl! world is now losing annually about 1.5 million hectares of total irrigated lands (240 million hectares) due mostly to salinization, mainly in drylands. Salt affected soils are widely distributed throughout the arid and semi-arid regions, and particularly severe in China (7 million ha), India (20 million ha), Pakistan (3.2 million ha), USA (5.2 million ha), as well as Near East, southern Europe and elsewhere. Demands on production have increased the pressure on existing productive land and moved the limits of production onto increasingly marginal lands. Wise land-use practices have yet to be developed for such conditions. The Executive Director of UNEP reported to the Governing Council in February 1992 concerning the "Status of Desertification and Implementation of the United Nations Plan of Action to Comtat Desertification (PACD)". The Report concludes that major efforts to implement the PACD had gJne into supporting measures rather than concrete corrective field operations. Little evidence of progrl!ss was found in irrigated croplands, rainfed croplands or rangelands. It was recommended that every piece of land should be used in keeping with its ecological characteristics, natural capabilities and constraints.

Plant Stems by Anonim Pdf

Stems, of various sizes and shapes, are involved in most of the organic processes and interactions of plants, ranging from support, transport, and storage to development and protection. The stem itself is a crucially important intermediary: it links above- and below ground organs-connecting roots to leaves. An international team of leading researchers vividly illustrate that stems are more than pipes, more than simple connecting and supporting structures; rather stems are critical, anatomically distinct structures of enormous variability. It is, to an unappreciated extent, this variability that underpins both the diversity and the success of plants in myriad ecosystems. Plant Stems will be a valuable resource on form/function relationships for researchers and graduate-level students in ecology, evolutionary biology, physiology, development, genetics, agricultural sciences, and horticulture as they unravel the mechanisms and processes that allow organisms and ecosystems to function. Syntheses of structural, physiological, and ecological functions of stems Multiple viewpoints on how stem structure relates to performance Highlights of major areas of plant biology long neglected

Towards the rational use of high salinity tolerant plants by Helmut Lieth,A.A. Al Masoom Pdf

The Symposium on high salinity tolerant plants, held at the University of Al Ain in December 1990, dealt primarily with plants tolerating salinity levels exceeding that of ocean water and which at the same time are promising for utilization in agriculture or forestry. These plants could be very useful for a country like the UAE where fresh water resources are very scarce and the groundwater available at some places is already very salty. More than 60 million woody trees/shrubs have been planted so far and more are planned for the inland plains underlain with brackish groundwater. These species were no solution for the widely barren shoreline of the UAE. Here mangrove species were of potential use, and one species, Avicennia Marina, occurs widely and has been successfully planted for about a decade. Converting the tree plantations into economically useful cropping systems is still a problem requiring much research and development. The book deals in several sections with conventional irrigation systems using marginal water. The species used in these systems are mostly hybrids of conventional crops. The irrigation systems, however, have similar problems as may be expected for irrigation with seawater. Papers show the participants' experiments in this area. The volume serves as a link between scientists working for the improvement of classical irrigation systems and those interested in the application of a new dimension of salinity levels for irrigation water.
