BENEFICIAL CHEMICAL ELEMENTS OF PLANTS Understand beneficial elements and their role in the future of botany and agriculture Beneficial elements are those which, while not essential to plant life, can provide stimulation and enhance plant growth. Properly harnessed, these elements can bolster plant growth in the face of environmental conditions—including drought, nutrient deficiency, and excessive soil salinity—and biotic stresses like pathogens and animal activity. As climate change and population growth pose increasingly serious challenges to agriculture and essential plant production, it has never been more important to unleash the potential of beneficial elements. Beneficial Chemical Elements of Plants is an essential resource for researchers and industry specialists looking to enhance their understanding of these elements and the range and variety of their enhancements to plant growth. Written by leading scholars in the field of plant stress tolerance and nutrient enrichment, it discusses not only the rich possibilities of beneficial elements but their mechanisms of action at both biochemical and molecular levels. It details the precise potential roles played by each major beneficial element and surveys a range of elemental responses to specific environmental conditions and plant stresses. Beneficial Chemical Elements of Plants readers will also find: Chapters covering beneficial elements including aluminum, cobalt, sodium, selenium, and silicon Discussion of application methods and typical plant responses Treatment of beneficial elements in a wider environmental context Beneficial element applications to the field of sustainable agriculture Beneficial Chemical Elements of Plants is a fundamental starting point for researchers and students in the fields of plant physiology, crop science, agriculture, and botany, as well as for professionals in the biotechnology and agricultural industries.

ETHYLENE IN PLANT BIOLOGY Comprehensive resource detailing the role of ethylene in plant development regulation, gene regulation, root development, stress tolerance, and more Ethylene in Plant Biology presents ethylene research from leading laboratories around the globe to allow readers to gain strong foundational coverage of the topic and aid in further ethylene research as it pertains to plant biology. The work covers general ideas as well as more specific and technical knowledge, detailing the overall role of ethylene in plant biology as a gaseous plant hormone that has emerged as an important signaling molecule which regulates several steps of a plant's life cycle. The ideas covered in the work range from discovery of ethylene, to its wide roles in plant growth and development, all the way to niche topics such as stress acclimation. Written by highly qualified authors in fields directly related to plant biology and research, the work is divided into 20 chapters, with each chapter covering a specific facet of ethylene or the interaction between ethylene and plant health. Topics discussed in the text include: Our current understanding of ethylene and fruit ripening, plus the role of ethylene in flower and fruit development Ethylene implications in root development and crosstalk of ethylene with other phytohormones in plant development Ethylene as a multitasking regulator of abscission processes and powerful coordinator of drought responses Mechanisms for ethylene synthesis and homeostasis in plants, along with ethylene and phytohormone crosstalk in plant defense Ethylene and metabolic reprogramming under abiotic stresses, as well as ethylene's applications in crop improvement For biologists, scientists, researchers, and policy makers in the agriculture and pharmaceutical industries, Ethylene in Plant Biology is a key resource to understand the state of the art in the field and establish a foundation of knowledge that can power future research efforts and practical applications.

Protect crop yields and strengthen ecosystems with this essential guide Research into weed management is an increasingly critical component of both environmental stewardship and food production. The potential cost of weed propagation can be measured in crop yield reductions, under-nourished populations, stymied economies, and more. The propagation of herbicide-resistant weed populations means that purely chemical weed management is no longer viable; food production can now be secured only with an ecological approach to weed control. Ecologically-Based Weed Management details such approaches and their potential to manage weeds across a range of agricultural and environmental contexts. It emphasizes the deployment of ecological principles to prevent weed infestations, reduce crop losses, and strengthen ecosystems. In a time when growing population and changing climates are placing enormous pressure on global food production, this approach to weed management has never been more vital. Ecologically-Based Weed Management readers will also find: A global team of expert contributors to a multidisciplinary approach Detailed discussion of topics like herbicide limitation, integrated weed management, and more Insights pertinent to agriculture, academia, government, industry, and more Ecologically-Based Weed Management is ideal for researchers in agriculture chemistry, weed science, agronomy, ecology, and related fields, as well as for regulators and advanced students.

Band XIb-2 ist - abgesehen von einigen Ergdnzungen zu den Bdnden XIa und XIb-1 - den Sekunddrstoffen der Papilionoideae gewidmet und bietet einen wohl einmaligen \berblick ]ber die Chemotaxonomie und die sekunddren Inhaltsstoffe dieser Pflanzengruppe. Er ist daher von speziellem Interesse f]r Leguminosenforscher, Pharmakologen, Phytochemiker und Ethnobotaniker. Wie die Bdnde XIa und XIb-1 enthdlt auch dieser Band zahlreiche Literaturhinweise und ein Register mit taxonomischem Index und Stichwortverzeichnis. Dieser letzte Band stellt nach etwa vierzigjdhriger Arbeit den Abschluss der Chemotaxonomie der Pflanzen von Robert Hegnauer dar. Der erste Band erschien 1962; bei der Aufnahme des Autors in die Leopoldina (1972) waren sechs Bdnde abgeschlossen, die alle Familien der hvheren Pflanzen mit Ausnahme der Leguminosen ber]cksichtigten. Diesen Bdnden folgten drei Nachtragsbdnde und ein Generalregister sowie drei Bdnde ]ber Leguminosen.
