The Long-Term Fertilization Trials in Halle (Saale)
With the “eternal rye” experiment, laid out by Julius Kühn in 1878, the Institute of Agricultural and Nutritional Sciences of the Martin Luther University Halle-Wittenberg has the second oldest long-term fertilization trial of the world after Rothamstedt (UK). In addition, four more long-term fertilization experiments as well as one soil development trial exist in Halle, all founded by Karl Schmalfuß in 1948/49. Wolfgang Merbach and Annette Deubel summarize the most important results and draw conclusions for the continuation of these internationally important experiments.
Plant Nutrition
This volume is a compilation of extended abstracts of all papers presented at the 14th International Plant Nutrition Colloquium. Over 500 oral and poster presentations illustrate current knowledge and research emphasis in this subject, providing a comprehensive view of the state of plant nutrition research.
Ecology and Evolution of the Grass-Endophyte Symbiosis
Endophytic fungi are common and diverse in plants. Yet the nature of their interactions with host plants, and how these interactions cascade upward to communities and ecosystems, is largely unknown. In the first book of its kind, Gregory P. Cheplick and Stanley H. Faeth synthesize existing studies of endophyte-grass symbioses within the context of modern ecological and evolutionary concepts. The authors cover a broad range of topics including the effects of endophytes on herbivory, host growth, physiology, reproduction, and competitive ability in a variety of grasses and environments. Clearly and engagingly written, Ecology and Evolution of the Grass-Endophyte Symbiosis highlights the most essential aspects of symbiosis ecology and evolution while suggesting avenues for future research.
Neotyphodium in Cool-Season Grasses
Divided into logical easy-to-use sections, Neotyphodium in Cool-Season Grasses is an up-to-date anthology of the latest knowledge on the genus Neotyphodium. This thorough text covers the molecular biology of Neotyphodium endophytes and their effects on grass hosts, invertebrate and vertebrate herbivores, and the plant communities in which they interact. The expert editors also include information on the commercial uses of endophytes in livestock and turf industries. Researchers and teachers in grass research, extension, agronomy, and animal toxicology, and university libraries with courses in these subjects should not be without this important text.
Boron in Plant and Animal Nutrition
The Boron '97 meeting was a great success in summarising all recent developments in basic and applied research on boron's function, especially in plants. New techniques have since been developed and new insight has been gained into the role of boron in plant and animal metabolism. Nevertheless, there were still lots of open questions. The aim of the present workshop held in Bonn as a satellite meeting to the International Plant Nutrition Colloquium was thus to gather all actual information which has been gained since the Boron '97 meeting and to compile knowledge, both from animal and plant sciences. Furthermore, applied aspects had to be addressed too, as there is an increasing awareness of...
Accelerated Plant Breeding, Volume 3
Plant improvement has shifted its focus from yield, quality and disease resistance to factors that will enhance commercial export, such as early maturity, shelf life and better processing quality. Conventional plant breeding methods aiming at the improvement of a self-pollinating crop, such as wheat, usually take 10-12 years to develop and release of the new variety. During the past 10 years, significant advances have been made and accelerated methods have been developed for precision breeding and early release of crop varieties. This work summarizes concepts dealing with germplasm enhancement and development of improved varieties based on innovative methodologies that include doubled haploidy, marker assisted selection, marker assisted background selection, genetic mapping, genomic selection, high-throughput genotyping, high-throughput phenotyping, mutation breeding, reverse breeding, transgenic breeding, shuttle breeding, speed breeding, low cost high-throughput field phenotyping, etc. It is an important reference with special focus on accelerated development of improved crop varieties.
Genes for Plant Abiotic Stress
Abiotic stresses caused by drought, salinity, toxic metals, temperature extremes, and nutrient poor soils are among the major constraints to plant growth and crop production worldwide. While crop breeding strategies to improve yields have progressed, a better understanding of the genetic and biological mechanisms underpinning stress adaptation is needed. Genes For Plant Abiotic Stress presents the latest research on recently examined genes and alleles and guides discussion of the genetic and physiological determinants that will be important for crop improvement in the future.
Assessing Bioavailability of Metals in Biosolids-Treated Soils
Plant-availability of metals in biosolids-treated soils may be mathematically described by Mt = C x [1 - e- (k x t)] where Mt (mg kg-1) is the cumulative metal removal from the biosolids-treated soils by growing and harvesting plants for t years, C is the total phytoavailable metal pool of the soil (mg kg-1) at t = 0, and k is the metal absorption rate coefficient (yr-1). The total available metal pool, C, is defined as metals extractable by organic acids in the rhizosphere of growing plants and k is related to the kinetics of metal release by organic acids. Half-life of the available metals in biosolids-amended soils may be derived from k.Experiments were conducted to characterize the concentration and composition of the organic acids. A successive extraction method was used to extract metals from biosolids-treated soils for determinging C and k. In this manner, the plant available metals of the biosolids-treated soils are defined by the total available metals, half-life, and duration of plant growing.
The Rhizosphere
Summarizing data on the processes that occur in soil-plant interaction, this text emphasizes the biochemistry and the role of organic compounds in the rhizosphere environment. It considers developments in experimental approaches to the biochemical and molecular interaction among plants, microbes, and soil components.
Plant Toxicology
In order to keep track of all the compounds and pathogens affecting plant metabolism and development, you would need to spend all your waking hours combing periodicals and the Internet in dozens of languages, as new toxins via pollutants and migratory or mutant pathogens are being discovered every day.
