Ecophysiology of Economic Plants in Arid and Semi-Arid Lands
This book deals with arid and semi-arid environments and their classification, and the physiological restraints and adaptations of plants to the environment. Further, it discusses economic botany and the needs and methods of conserving economic plants. A broad view is taken regarding the definition of economic plants, taking into account their value to the environment as well as to man and to livestock. The individual deserts and associated semi-arid regions are described in separate chapters, providing background information on the regional environments in terms of climate and major plant formations. The economic plants within these formations, their usages, geographical distribution together with their morphological and physiological adaptations are treated in detail.
Plant Resources of Arid and Semiarid Lands
Plant Resources of Arid and Semiarid Lands: A Global Perspective is a collection of papers that evaluates the existing native plant resources in the arid and semiarid regions. The papers deal with the resources found in these arid regions such as food potential, forage, fuel, fiber, medicinal or industrial uses. The book covers the arid regions of Africa, Australia, the Indian subcontinent, Middle East, North America, China, South America, and the USSR. The treatment of these regions includes geographical descriptions such as area, annual precipitation, temperature, humidity, wind ranges or patterns, and seasons. These papers also discuss the effects of topography on water drainage and loss,...
Plants for Arid Lands
Economic plants have been defined by SEPASAT as those plants that are utilised either directly or indirectly for the benefit of Man. Indirect usage includes the needs of Man's livestock and the maintenance of the environment; the benefits may be domestic, commercial or aesthetic. Economic plants constitute a large and so far uncalculated percentage of the quarter of a million higher plants in the World today. However, it has been calculated that 10% (25 000) of these species are now on the verge of extinction and extinction means that a genetic resource that could be of benefit to Man will be lost for ever. Furthermore, for every species lost an estimated 10-30 other dependent organisms are also doomed. Fewer than 1 per cent of the World's plants have been sufficiently well studied for a true evaluation of the potential floral wealth awaiting discovery, not only in the rain forests, which man is now actively destroying at a rate of 20 ha a minute, but also in the very much neglected dry areas of the World.
Propagation of Horticultural Plants
In semi arid and arid regions of the country, a vast land resource (39.54 m ha) is available which is underutilized, having good potential of expansion for quality production of several horticultural, medicinal, spices, ornamental and crops of economic importance. The horticulture can play vital role in diversification of these untapped natural resources. The development of arid horticulture is not very old; the published literature on many crops of economic importance and their multiplication is also scanty. Looking to prospects of such underutilized crop, its propagation methodology should be standardized for large scale plantation through availability of quality planting material. The wor...
Steppes
Steppes—semi-arid biomes dominated by forbs, grasses, and grass-like species, and characterized by extremes of cold and heat—occupy enormous areas on four continents. Yet these ecosystems are among the least studied on our planet. Given that the birth and evolution of human beings have been so intimately interwoven with steppe regions, it is amazing that so few attempts have been made to compare and quantify the features of these regions. In this ground-breaking volume, five leading voices in horticulture—all staff members of Denver Botanic Gardens—examine the plants, climate, geology, and geography of the world’s steppes: central Asia, central and intermountain North America, Patagonia, and South Africa. Drawing upon their first-hand experience, the writers illuminate the distinctive features of each region, with a particular emphasis on the striking similarities between their floras. Each chapter includes a primer of species of horticultural interest—a rich resource for readers with an interest in steppe plants.
Vegetation and climate interactions in semi-arid regions
The chapters in this section place the problems of vegetation and climate interactions in semi-arid regions into the context which recur throughout the book. First, Verstraete and Schwartz review desertification as a process of global change evaluating both the human and climatic factors. The theme of human impact and land management is discussed further by Roberts whose review focuses on semi-arid land-use planning. In the third and final chapter in this section we return to the meteorological theme. Nicholls reviews the effects of El Nino/Southern Oscillation on Australian vegetation stressing, in particular, the interaction between plants and their climatic environment. Vegetatio 91: 3-13...
Arid Shrubland Plants of Western Australia
An attractive and accessible guide to identification and appreciation of the native flora of the arid region of Western Australia, this revised edition of Arid Shrubland Plants of Western Australia now describes over 200 herbs, grasses, shrubs and trees. Each species is illustrated in colour, and the non-technical text gives vegetative and floral characteristics, habitat, forage value, the response to grazing and, where appropriate, the value of plants for degraded land and mine site rehabilitation. The only book of its kind, Arid Shrubland Plants of Western Australia is an important resource for pastoralists, mining companies, geologists, shire councils and native tree growers, and will also appeal to travellers and lovers of the Australian bush.
Plants Tolerant of Arid, Or Semi-arid, Conditions with Non-food Constituents of Potential Use
Tabular list of 298 plant sources of essential oils, fibers, firewood, gums and resins, latexes, oilseeds, pesticides, pharmaceuticals, tannins, and waxes.
