Beneficial Plant-Bacterial Interactions
Author: Bernard R. Glick
Publisher: Springer Nature
ISBN: 303044368X
Category : Science
Languages : en
Pages : 390
Book Description
This book provides a straightforward and easy-to-understand overview of beneficial plant-bacterial interactions. It features a wealth of unique illustrations to clarify the text, and each chapter includes study questions that highlight the important points, as well as references to key experiments. Since the publication of the first edition of Beneficial Plant-Bacterial Interactions, in 2015, there has been an abundance of new discoveries in this area, and in recent years, scientists around the globe have begun to develop a relatively detailed understanding of many of the mechanisms used by bacteria that facilitate plant growth and development. This knowledge is gradually becoming an integral component of modern agricultural practice, with more and more plant growth-promoting bacterial strains being commercialized and used successfully in countries throughout the world. In addition, as the world’s population continues to grow, the pressure for increased food production will intensify, while at the same time, environmental concerns, mean that environmentally friendly methods of food production will need to replace many traditional agricultural practices such as the use of potentially dangerous chemicals. The book, intended for students, explores the fundamentals of this new paradigm in agriculture, horticulture, and environmental cleanup.

Biocomplexity of Plant-Fungal Interactions
Author: Darlene Southworth
Publisher: John Wiley & Sons
ISBN: 0813815940
Category : Science
Languages : es
Pages : 246
Book Description
Plants interact with a wide variety of organisms in their natural growing environments. Key amongst these relationships is the interplay between plants and diverse fungal species that impact plants in complex symbiotic, parasitic and pathogenic ways. Biocomplexity of Plant-Fungal Interactions explores a broad spectrum of research looking at both positive and negative interactions of these relationships on plants and their ecosystems. Biocomplexity of Plant-Fungal Interactions takes a more holistic view of the plant-fungal interactions than most traditional volumes on the topic. Focusing on the truly complex biological interplay among plants and fungi, as well as other organisms—mammals, insects, bacteria, viruses, this book provides a unique perspective on this fundamentally important relationship. Chapters are written from molecular, evolutionary and ecological perspectives to provide readers with a full understanding of the diverse implications of plant-fungal interactions. Written by a global team of experts from varied scientific backgrounds, Biocomplexity of Plant-Fungal Interactions will be an essential title for readers looking for a better understanding of the diverse array of interactions between plants and fungi in natural ecosystems.

Vascular Differentiation and Plant Growth Regulators
Author: Lorin W. Roberts
Publisher: Springer Science & Business Media
ISBN: 3642734464
Category : Science
Languages : en
Pages : 165
Book Description
The main objective of the book is to provide an up-to-date examination of the possible roles of plant hormones during the cytodifferentiation of xylem and phloem elements in higher plants. Various facets of vascular differentiation, as cell determination, cell cycle activity, and the biochemical events in xylogenesis, are analyzed. Furthermore, the latest information on the roles of auxins, cytokinins, gibberellins, ethylene, and abscisic acid during vascular cell formation are summarized. A theoretical discussion of the six-point hypothesis and the vascular adaptation hypothesis is included. The experimental induction of vascular differentiation under tissue culture conditions is critically appraised and a concluding chapter covers the interactions between physical factors, growth regulators, and differentiation.

Utilization of Residual Forest Biomass
Author: Pentti Hakkila
Publisher: Springer Science & Business Media
ISBN: 3642740723
Category : Technology & Engineering
Languages : en
Pages : 582
Book Description
An increase in the demand for wood results in improved recovery and less residual biomass in the forests. Paradoxically, interest in forest residue as a renewable source of raw material seems to be in a reverse ratio to its availability in a certain area. Finland and Sweden are probably more dependent on forestry and forest in dustries than any other developed countries in the world. A sufficiency of raw ma terial for integrated forest industries is vital for the national economy of both countries, and a great deal of attention is being paid to the long-term potential of unutilized biomass left behind in logging operations. Furthermore, since these countries possess no reserves of fossil fuels, and since their per-capita consump tion of primary energy is exceptionally high, they also consider unmerchantable forest biomass a realistic source of indigenous energy. A joint Nordic research project on harvesting and utilization of logging residue was carried out in 1969-1976 under the auspices of the Nordic Research Council on Forest Operations. This fruitful cooperation soon gave rise to related national projects in Sweden, Finland, Norway, and Denmark, stimulating further research and producing practical applications. Concurrently, particularly after the worldwide energy crisis in 1973, research on all aspects of utilization of forest bio mass mushroomed in the United States, Canada, and the Soviet Union. An ex plosive increase occurred in both the number and diversity of biomass studies.

Growth Stresses and Strains in Trees
Author: Robert R. Archer
Publisher: Springer Science & Business Media
ISBN: 3662025116
Category : Technology & Engineering
Languages : en
Pages : 251
Book Description
Although over 40 years have passed since Jacobs (1945) convincingly established the basic radial pattern of residual growth stress in growing trees, yet this phenomenon is still not widely appreciated in wood science and technology circles. This is in spite of the fact that the presence of these stresses of sizeable magnitudes has long been recognized as a primary cause of shakes and splits in logs as well as the warping of lumber sawn in the green condition. The presentation of the subject of growth stresses in trees presents some special problems due to the wide range of specialists who potentially might have an interest in the subject. For example, tree physiologists interested in questions such as the relation of mechanical stress to stem taper and the role of reaction wood and gravity forces in determining tree crown form encounter growth stress models. Silvi culturists interested in the relation ofthinning practices to wood quality find that wood properties are correlated with growth stress levels which are in turn significantly changed by cutting practices. Wood techno logists interested in the relation of residual growth stress gradients in green logs to the dimensional quality of sawn and seasoned lumber are forced to take a more quantitative approach to the effect of growth stresses than might have been the case in the past.

Natural Products of Woody Plants
Author: John W. Rowe
Publisher: Springer Science & Business Media
ISBN: 3642740758
Category : Science
Languages : en
Pages : 1275
Book Description
Wood as found in trees and bushes was of primary importance to ancient humans in their struggle to control their environment. Subsequent evolution through the Bronze and Iron Ages up to our present technologically advanced society has hardly diminished the importance of wood. Today, its role as a source of paper products, furniture, building materials, and fuel is still of major significance. Wood consists of a mixture of polymers, often referred to as lignocellulose. The cellulose micro fibrils consist of an immensely strong, linear polymer of glucose. They are associated with smaller, more complex polymers composed of various sugars called hemicelluloses. These polysaccharides are embedded in an amorphous phenylpropane polymer, lignin, creating a remarkably strong com posite structure, the lignocellulosic cell wall. Wood also contains materials that are largely extraneous to this lignocellulosic cell wall. These extracellular substances can range from less than 1070 to about 35% of the dry weight of the wood, but the usual range is 2% -10%. Among these components are the mineral constituents, salts of calcium, potassium, sodium, and other metals, particularly those present in the soil where the tree is growing. Some of the extraneous components of wood are too insoluble to be ex tracted by inert solvents and remain to give extractive-free wood its color; very often these are high-molecular-weight polyphenolics.
