Vascular Wilt Diseases of Plants: Basic Studies and Control
ISBN: 9783642731686 / Angielski / Miękka / 590 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. It is apparent that wilt diseases continue to be a major problem in crop production because of the number of crops affected, the number and genetic variability of pathogens involved, and their widespread occurrence throughout tropical and temperate regions under a variety of cropping systems. It is also apparent, however, that new understandings and approaches, often in combinations not previously discerned, offer exciting new prospects for research, understanding and practical control methods. The current state-of-the-art and fields for further studies were discussed by researchers actively...

Wood-Water Relations
ISBN: 9783642736858 / Angielski / Miękka / 283 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Wood is formed in an essentially water-saturated environment in the living tree, and the cell wall remains in this state until the water flow from the roots is interrupted, such as by felling the tree. The wood then begins to lose most of its moisture by drying, resulting in changes in most of its physical properties. These changes, and their relationship to the environment to which the wood is subsequently ex posed, are the subject of this book. The text consists of six chapters. The first chapter discusses cer tain empirical relationships between wood and water, methods of measuring wood...

Wood Variation: Its Causes and Control
ISBN: 9783642740718 / Angielski / Miękka / 363 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Wood is the usual end product of a forestry operation. Because of its importance, numerous studies have been made relative to wood prop erties, the causes of wood variation, and how best to develop wood for desired products. There is voluminous literature related to these subjects, but it is neither well known nor appreciated by foresters because the publications are often not available or are not well understood by the forester or by those who use the wood. Frequently, the literature is confusing and contradictory, making it difficult for the nonspecialist to use what information is...

Genetic Effects of Air Pollutants in Forest Tree Populations: Proceedings of the Joint Meeting of the Iufro Working Parties Genetic Aspects of Air Pol
ISBN: 9783642745508 / Angielski / Miękka / 201 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Air pollutants provide environmental conditions that drastically differ in many respects from those to which forest trees are naturally adapted. Leading experts in the field here consider these questions of immediate relevance arising from the changing environment: (1) Do air pollutants introduce effects of selection that differ from those known for populations that are not subject to such stress conditions? (2) If air pollutants introduce quantitatively or even qualitatively novel selective effects, which consequences might arise from the adaptation of forest tree populations to the present...

Seed Germination in Desert Plants
ISBN: 9783642757006 / Angielski / Miękka / 253 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. During germination, the most resistant stage of the life cycle - the seed - changes to the most sensitive stage, namely the seedling. Therefore, in desert plant species seed dispersal and subsequent germination in the optimum time an place place are particularly critical parameters. Discussed here are the ways and means by which desert plants have adapted through the course of evolution to their extreme environment. Two such strategies which have evolved are a) plants with relatively large and protected seeds which germinate when the chance of seedling survival is high and the risk relatively...

Electron Microscopy of Plant Pathogens
ISBN: 9783642758201 / Angielski / Miękka / 336 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Plants, fungi, and viruses were among the first biological objects studied with an electron microscope. One of the two first instruments built by Siemens was used by Helmut Ruska, a brother of Ernst Ruska, the pioneer in constructing electron microscopes. H. Ruska published numerous papers on different biological objects in 1939. In one of these, the pictures by G. A. Kausche, E. Pfankuch, and H. Ruska of tobacco mosaic virus opened a new age in microscopy. The main problem was then as it still is today, to obtain an appropriate preparation of the specimen for observation in the electron...

Forest Decline in the Atlantic and Pacific Region
ISBN: 9783642769979 / Angielski / Miękka / 366 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Forest damage, forest decline, forest dieback - not related to biotic agents - is occurring in the Atlantic and Pacific regions. In Europe and Eastern North America this serious problem is considered to be, at least to some part, related to industrial air pollutants and their atmospheric conversion products, such as acid rain or ozone. Forest declines in the Pacific region have been attributed largely to natural causes involving forest dynamics, since air pollution and other negative anthropogenic influences are practically absent. Presented here are typical decline phenomena in the Pacific...

Heterosis: Reappraisal of Theory and Practice
ISBN: 9783642819797 / Angielski / Miękka / 292 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. When trying to solicit authors for this book it became apparent that the causal factors for heterosis at the physiological and biochemical level are today almost as obscure as they were 30 years ago. Though biometrical-genetical analyses point to dispersion of complementary genes - not overdominance - as the major cause of the phenomenon, plant breeders' experience still suggests a cautious, pragmatic approach to the dominance-overdominance controversy in breeding hybrid cultivars. Thus we are faced with a striking discordance between our limited comprehension of the causal factors and...

In 1999, the Museum of Fine Arts in Houston reportedly paid $1.25 million for a single painting, "Magnolias on Gold Velvet Cloth." A striking close-up of magnolia buds, this painting is just one high-profile example of the evocative power magnolias have on art and culture. Gardeners have revered the plants since they were first introduced into cultivation more than three hundred years ago, and they continue to be a showpiece addition to gardens. From serving as medicine in Japan and China, to dotting lawns and flags in the American South, magnolias are a true worldwide favorite....

ISBN: 9783642647956 / Angielski / Miękka / 475 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. During the last decade, forest decline has become increasingly apparent. The decline in forest health was often reported to be associated with air pollution. The present study on Norway spruce stands in the Fichtelgebirge analyses various processes interacting within forest ecosystems. It covers transport and deposition of air pollutants, the direct effects of pollutants on above-ground plant parts, the responses of soil to acid rain, and the changing nutrient availability, and the accompanying effects on plant metabolism and growth. The role of fungi, microorganisms and soil animals in the...
