This book was released on 2012-12-06 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presented here are modern and classical aspects of cytogenetics as well as biotechnology in relation to improvement of the Festuca-Lolium group of grasses. Festuca and its close relative Lolium are very valuable genera of temperate agriculture. These fascinating genera contain some highly productive, nutritious, and well-adapted grasses widely used for agricultural and recreational purposes world wide. The book is organizedinto 15 chapters devoted to taxonomy and systematics; species evolution and divergence by increase in chromosome number as well as by change in DNA content; genetic control of chromosome pairing and its breeding and phylogenetic implications; B chromosomes, induced polyploidy and haploidy inrelation to varietal improvement; wide hybridization, genome relationships, and plant improvement; genomic balance in relation to hybrid fertility and hererosis breeding; biotechnology and its potential applications in plant improvement. It is of special interest to geneticists, taxonomists, evolutionists, biotechnologists, and plant breeders.

This book was released on 2017-07-04 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding plant responses to abiotic stresses is central to our ability to predict the impact of global change and environmental pollution on the production of food, feed and forestry. Besides increasing carbon dioxide concentration and rising global temperature, increasingly frequent and severe climatic events (e.g. extended droughts, heat waves, flooding) are expected in the coming decades. Additionally, pollution (e.g. heavy metals, gaseous pollutants such as ozone or sulfur dioxide) is an important factor in many regions, decreasing plant productivity and product quality. This Research topic focuses on stress responses at the level of whole plants, addressing biomass-related processes (development of the root system, root respiration/fermentation, leaf expansion, stomatal regulation, photosynthetic capacity, leaf senescence, yield) and interactions between organs (transport via xylem and phloem, long-distance signaling and secondary metabolites). Comparisons between species and between varieties of the same species are helpful to evaluate the potential for species selection and genetic improvement. This research topic is focused on the following abiotic stresses and interactions between them: - Increased carbon dioxide concentration in ambient air is an important parameter influenced by global change and affects photosynthesis, stomatal regulation, plant growth and finally yield. - Elevated temperature: both the steady rise in average temperature and extreme events of shorter duration (heat waves) must be considered in the context of alterations in carbon balance through increased photorespiration, decreased Rubisco activation and carboxylation efficiency, damage to photosynthetic apparatus, as well as loss of water via transpiration and stomatal sensitivity. - Low temperatures (late frosts, prolonged cold phases, freezing temperature) can decrease overwintering survival rates, productivity of crop plants and species composition in meadows. - Water availability: More frequent, severe and extended drought periods have been predicted by climate change models. The timing and duration of a drought period is crucial to determining plant responses, particularly if the drought event coincides with an increase in temperature. Drought causes stomatal closure, decreasing the cooling potential of transpiration and potentially leading to thermal stress as leaf temperature rises. Waterlogging may become also more relevant during the next decades and is especially important for seedlings and young plants. It is not the presence of water itself that causes the stress, but the exclusion of oxygen from the soil which causes a decrease in respiration and an increase in fermentation rates followed by a period of potential oxidative stress as water recedes. - Salinity: high salt concentration in soil influences soil water potential, the water status of the plant and hence affects productivity. Salt tolerance will become an important trait driven by increased competition for land and the need to exploit marginal lands.Understanding plant responses to abiotic stresses is central to our ability to predict the impact of global change and environmental pollution on the production of food, feed and forestry.

Available in PDF, EPUB and Kindle. Book excerpt: Grassland farming in Europe was already established during the settlement of the rst farmers together with their domesticated animals after the last ice age. Since then, grassland provides the forage basis to feed ruminant animals for the p- duction of meat and milk. Depending on the ecological conditions and intensity of usage, various plant communities with different species developed, displaying a rich biodiversity. With the introduction of improved crop rotations at the end of the 16th century, grasses and legumes were also grown to an important extent as forage crops on arable land. In the last decades the importance of amenity grasses increased markedly, due to the demand of the society for new usages like landscape protection. Around 1900 interested farmers and academics identi ed the need for gra- land improvement through systematic selection and seed production. This marks the beginning of breeding and research in companies but also at universities and specialized research institutes. Plant collection started with many of the species that are still of importance today. The collected materials were grouped according to the intended use and some type of phenotypic selection was applied. Seed mul- plication of such populations was performed in pure stands and the harvested seed was marketed. Although the vegetative biomass and its quality are of utmost imp- tance in forage crop breeding, it is the seed yield potential which determines the commercial success of a new variety.
