Description : Read Now Survival Strategies Of Annual Desert Plants by Yitzchak Gutterman and you can download with pub, pdf, txt, doc, and more file format with free account. annual desert plant species of unrelated taxa in the negev desert of israel have developed complementary sets of adaptations and survival strategies as ecological equivalents with physiological, morphological and anatomical resemblances, in the various stages of their life cycles. after 40 years of research in hot deserts yitzchak gutterman provides a comprehensive treatise of such adaptations and strategies. in doing so he covers the following topics: post-maturation primary seed dormancy, which prevents germination of maturing seeds before the summer; seed dispersal mechanisms with escape or protection strategies; cautious or opportunistic germination strategies; seedling drought tolerance. the day-length is an important factor in regulating flowering as well as the phenotypic plasticity of seed germination which is also affected by maternal factors.

Description : Read Now Dispersal Biology Of Desert Plants by Karen van Rheede van Oudtshoorn, Margaretha W. van Rooyen and you can download with pub, pdf, txt, doc, and more file format with free account. dispersal processes have important effects on plant distribution and abundance. although adaptations to long range dispersal (telechory) are by no means rare in desert plants, many desert plant species do not possess any features to promote dispersal (atelechory), while others have structures that hamper dispersal (antitelechory). the high frequency with which atelechorous and antitelechorous mechanisms are present in plants inhabiting arid areas indicates the importance of these adaptations. among the benefits derived from these adaptations are the spreading of germination over time, the provision of suitable conditions for germination and subsequent seedling establishment, and the maintenance of a reservoir of available seeds (seed bank). this book describes the ways and means - anatomical, morphological and ecological - by which dispersal in desert plants has evolved to ensure the survival of these species in their harsh and unpredictable environment.

Description : Read Now Plants For Arid Lands by G.E. Wickens, David. V. Field, Joe R. Goodin and you can download with pub, pdf, txt, doc, and more file format with free account. 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.

Description : Read Now Desert Plants by Kishan Gopal Ramawat and you can download with pub, pdf, txt, doc, and more file format with free account. deserts appear very fascinating during our short visits. however, the lives of plants and animals are very dif?cult under the harsh climatic conditions of high tempe- ture and scant water supply in deserts, sometimes associated with high concent- tions of salt. the editor of this book was born and brought up in the great indian desert, and has spent much of his life studying the growth and metabolism of desert plants. it is very charming on a cool summer evening to sit at the top of a sand dune listening only to blowing air and nothing else. it has been my dream to prepare a volume on desert plants encompassing various aspects of desert plant biology. in this book, i have tried to present functional and useful aspects of the vegetation resources of deserts along with scienti?c input aimed at understanding and impr- ing the utility of these plants. the scant vegetation of deserts supports animal life and provides many useful medicines, timber and fuel wood for humans. therefore, there are chapters devoted to medicinal plants (chap. 1), halophytes (chaps. 13, 14), and fruit plants (chaps. 17, 20). desert plants have a unique reproductive biology (chaps. 9–11), well-adapted eco-physiological and anatomical charact- istics (chap. 7), and specialised metabolism and survival abilities. these plants are dif?cult to propagate and pose many problems to researchers developing biote- nological approaches for their amelioration (chaps. 18–20).

Weber and you can download with pub, pdf, txt, doc, and more file format with free account. the halophytes are highly specialized plants, which have greater tolerance to salt. they can germinate, grow and reproduce successfully in saline areas which would cause the death of regular plants. most halophytic species are found in salt marsh systems along seashores or around landlocked inland lakes and flat plains with high evaporation. the halophytes play very significant role in the saline areas specially in the coast by overcoming the salinity in different ways, viz. with regulating mechanisms in which excess salts are excreted and with out regulating mechanism, which may include succulents or cumulative types. besides that they protect coast from erosion and cyclones, provide feeding ground and nursery for fish, shrimps and birds. halophytes get increasing attention today because of the steady increase of the salinity in irrigation systems in the arid and semi-arid regions where the increasing population reaches the limits of freshwater availability. in many countries, halophytes have been successfully grown on saline wasteland to provide animal fodder and have the potential for rehabilitation and even reclamation of these sites. the value of certain salt-tolerant grass species has been recognized by their incorporation in pasture improvement programs in many salt affected regions throughout the world. there have been recent advances in selecting species with high biomass and protein levels in combination with their ability to survive a wide range of environmental conditions, including salinity.
