The book contains the proceedings of the Fifth International Wheat Conference at which leading international scientists reviewed current research issues and developments in wheat improvement. The debated topics cover breeding and genetics, genetic resources and importance of free germplasm exchange, breeding for biotic and abiotic stresses, physiology, agronomy and mineral nutrition, grain quality and biotechnology. A significant number of presentations were made by participants from the former USSR and Eastern and Central Europe, making this book also a prime reference for current wheat research and production status in these countries. This book provides an opportunity for wheat scientists interested in global wheat improvement issues to obtain an insight into the research that is currently being conducted worldwide and the prospects of further improvement to meet the increasing demands for this food commodity.

Grain yield and end-use quality are the most important characteristics for hard red winter wheat (Triticum aestivium L.). Improvement of grain quality characteristics of grain from a given growing season and location requires systematic understanding of the genotype chosen, the production environment, and also knowing the consequence of rate and time of individual production packages such as seed treatment, seed rate, nitrogen (N) fertilization, and foliar fungicide applications. The objectives of this study were to: identify the effects of seed rate, genotype, and N top-dressed on yield, agronomic characteristics, and end-use quality of winter wheat; and to determine the effects of seed treatment and flag leaf foliar fungicide application on yield and agronomic characteristics of wheat cultivars. Two experiments were conducted at Havelock, near Lincoln, NE and the High Plains Agricultural Lab (HPAL), near Sidney, NE in 2014 and 2015 using randomized complete block design with split factorial arrangement. Overall foliar N increased grain yield, grain protein concentration, other baking quality indicators such as flour water absorption, peak height, tail area, weakening slope, and depressed grain volume weight, mixing time, and tolerance. Similarly, increased seed rate improved grain yield, seed weight, grain volume weight, flour yield, mixing time, and mixing tolerance. Increased seed rate reduced grain protein, flour water absorption, tail area, peak height, and weakening slope. Seed treated with EverGol Energy and Gaucho showed improved seedling emergence, leaf greenness, grain yield, and seed weight. Application of foliar fungicide at flag leaf stage improved grain yield, seed weight, and leaf area. Among the six genotypes evaluated, ‘Settler CL’ and ‘Freeman’ had the highest overall grain yield. The study demonstrated the importance of seeding rate and the existence of a wider than expected tolerance range for seeding rate. The study also demonstrated the importance of in-season nitrogen top dress and foliar fungicide application to increased winter wheat grain yield and grain quality in Nebraska. However, further research is recommended to fine-tune the factors and interdependence of response in relation to a specific location, season or the prevailing weather condition, and the specific attribute of the genotype seeded.

Senescence and Aging in Plants reviews the state of knowledge in the processes involved in plant senescence and aging. The book begins by discussing the emergence of senescence as a concept; experimental analysis of senescence; and patterns of senescence. It then examines membrane deterioration during senescence; photosynthesis in relation to leaf senescence; senescence of detached plant organs; changing patterns of nucleic acid and protein synthesis during senescence; and degradative and associated assimilatory aspects of nitrogen removal. This is followed by chapters on aspects of ethylene that may impinge upon its role in promoting senescence of higher plants; the role of cytokinins in plant senescence; the promoters and retardants of senescence; and the role of calcium in plant senescence. The concept of whole plant senescence is discussed, which can be subdivided into patterns, correlative controls, cessation of vegetative growth, declining assimilatory processes, assimilate partitioning, and hormonal controls. The final chapters cover the deterioration of cellular membranes during the plant aging process and seed aging.
