Whittaker vorgeschlagenen 5-Reiche-System unterteilt man die Organismen in Prokaryonten (Prokaryotae, Monera), Protisten (Protoctista), Pilze (Fungi, Eumycota), Tiere (Animalia) und Pflanzen (Plantae). Weltweit sind etwa 75.000 verschiedene Pilzarten bekannt. Diese werden in folgende Gruppen unterteilt: Algenpilze (Chytridiomycota), Jochpilze (Zygomycota), Schlauchpilze (Ascomycota), Ständerpilze (Basidiomycota) und imperfekte Pilze (Deuteromycota, Fungi imperfecti) (Alexopoulus et al. 1996). Die Schimmelpilze bilden keine taxonomische Einheit, diesem Begriff werden Pilze unterschiedlicher taxonomischer Gruppen zugeordnet. Die Schleimpilze (Myxomycota) und Oomycota werden heutzutage zur Gruppe der Protisten gezählt (beide Gruppen besitzen Zellwände aus Zellulose). Es sind ca. 20.000 Arten von Basidiomycota bekannt. Dazu zählen die meisten als Speisepilze bekannten Arten wie z.B. `Hutpilze`, `Baumpilze`, Boviste, Erdsterne, Nestlinge, Kugelwerfer und die Brandpilze (Ustomycetes). Bei der Gruppe der Schlauchpilze (Ascomycota) findet die sexuelle Vermehrung durch Ascosporenbildung in speziellen schlauchförmigen Zellen, den sogenannten Asci statt. Insgesamt sind bei den Ascomyceten ca. 32.000 Arten bekannt. Zu diesen werden neben den Hefen (Endomycetes) auch die meisten Flechtenpilze gezählt. Von den Jochpilzen sind nur etwa 650 Arten bekannt. Wichtige Vertreter sind Lebensmittelverderber wie der Köpfchenschimmel Mucor, Rhizopus und Absidia und einige Bodenpilze (Mortierella). Eine Toxinbildung durch Zygomycota ist nicht bekannt. ····· 10361107304

In addition, renewable energy has the potential to create many employment opportunities at all levels, especially in rural areas. The need to boost the efforts for further development and promotion of renewable energy sources has been felt world over in light of high prices of crude oil. A disparaging part of the solution lies in promoting renewable energy technologies as a way to address concerns about energy security, economic growth in the face of rising energy prices, competitiveness, health costs and environmental degradation. The cost-effectiveness of Wind and Small Hydro power energy should also be taken into account. An emphasis should be given on presenting the real picture of massive renewable energy potential it would be possible to attract foreign investments to herald a Green Energy Revolution in India.

This progress is dependent on several factors such as applied technique, plant material preparation and medium composition, especially, plant growth regulators. Successful micropropagation of apple using pre-existing meristems (culture of apical buds or nodal segments) is influenced by several internal (physiological state, genotype), and external (medium composition, technique, in vitro conditions) factors. Different stages of apple micropropagation such as shoot multiplication, rooting of microshoots and acclimatization were strongly dependent upon medium composition. In this book, mainly impact of medium composition (plant growth regulators, mineral nutrients, organic and gelling agents) on growth asects such as: multiplication rate, shoot elongation, bud formation, leaf development, callusing and rooting of different apple genotypes cultured on gelled basal Murashige-Skoog (MS) medium are discussed in details. ····· 10361100989

This is where molecular markers will be handy in determining genetic diversity and this will help in predicting hybrid performance. An essential assumption underlying the use of DNA markers for predicting hybrid performance is that a strong linear correlation exists between heterozygosity and heterosis (Singh et al., 2006). Hence, the investigation of correlation existed between `Molecular marker polymorphism and hybrid performance was undertaken in terminal water stress condition in pearl millet for yield and drought resistance traits.We have tried to investigate the above assumption by using molecular markers (RAPD & SSR) diversion and morphological diversion (Mahalanobis`s D2 clustering ) and its correlation with heterosis (MPH, BPH) in pearl millet.

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The book focusses on one of the most complex and difficult problems in subsurface flow: the transport of water and dissolved substances through unsaturated soils. The predominantly vertical flow in the unsaturated zone is governing the processes of groundwater recharge as well as the input of any kind of waterborn substances that may be transported from the surface through the unsaturated zone into the groundwater body. The book focusses on analyzing the transport of water and solutes in unsaturated-saturated porous media with special emphasis on macropore effects due to plant roots - a significant effect in agricultural areas. Another specific strength of the present book is to be seen in the fact that a unique set of relatively large soil column tests has been conducted in a field setup, in which the effect of decayed plant roots channels on solute transport processes was investigated. These intensive field tests and the new results derived from the experiments provide a significant step forward in our understanding and quantification of the role of macropores connected with plant root channels. ····· 1036199136

It has the slowest early growth and the lowest nutrient uptake initially which increases rapidly afterwards. Approximately the uptake of 76% of total N, 86% of P and 82% of K take place in cotton between 49-99 days after planting. Broadcasting of fertilizers, especially P and K, produces fixation problems due to more soil contact. Nearly 58-71%, 30-40% and less than 2% of total cotton growing roots are located in the top 20, 20-40 and below 40cm soil depth, respectively. Further, it is feasible to grow cotton with reduced tillage. The reduced-tillage production methods results into decrease in the number of tractor operations by 41% to 53%, fuel use by 48% to 62% and overall production costs by 14% to 18%.

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This contribution proposes an integrated approach to detect and quantify land-use and land-cover changes as a basis for studying and predicting changes in environmental processes leading to desertification. The approach has been applied in Tabernas (Almería, Southeast Spain), a representative area of the Mediterranean region where a combination of extreme environmental conditions and modifications of the land-use pattern that occurred in the last decades have led to increase the risk of desertification. The approach is based on multi temporal records of remotely sensed data and field survey. Sets of aerial photographs of the fifties, the eighties and the nineties in combination to satellite images and other thematic data were used to map land use and cover in the three periods. During the past five decades 32% of dry farming has changed into irrigation, abandoned land and activities of none-vegetation cover. The new uses have exerted pressure on the environment that lead to an increase in desertification processes. In addition to the anthropogenic processes, the relationship between desertification and geological processes is also analysed in this work. ····· 1036191722

Hence, the need of in-silico methods for protein secondary structure prediction is being driven by above listed limitations. Over a number of years, various transmembrane region predictors has been developed using computational approach. In this book, a connectionist (ANN-Artificial Neural Network) model has been developed for prediction of alpha helical transmembrane region using amino acid properties rather than using the traditional hydrophobicity approach. The best connectionist model developed in this book, achieved an accuracy of 73.31%, which seems to be relatively better than the methods developed earlier by different researchers. This book will be equally helpful to bioinformatician, molecular biologist as well as computational biologist in solving various complex biological problems that could not be solved with the traditional approach. ····· 1036191433
