Environmental, Physiological and Chemical Controls of Adventitious Rooting in Cuttings provides a review of the environmental, physiological and chemical controls of adventitious rooting in cuttings obtained from plants. In plants, adventitious roots, which are highly useful for vegetative propagation (or clonal propagation) are produced mainly from leaves, hypocotyls, stems or shoots. Vegetative propagation may occur naturally by using propagules such as roots, underground and aerial stems, leaves, buds and bulbils. It may also be done artificially through regenerative organs (rhizomes, bulbs, and corms) and by utilizing specialized methods, like cutting, grafting and layering. This book covers the latest tactics surrounding these processes. As a plethora of factors affect the adventitious rooting of cuttings, adding to the complexity of the phenomenon. The main factors which control adventitious root formation are types of cuttings, presence of leaf area on cuttings, types of hormones and their concentration, duration of hormonal treatment (quick dip, long soak, dry dip, spray dip, or total immerse method), maturation (juvenile or mature), genotype, explant position, and more, all of which are discussed here. - Provides a comprehensive and exclusive book on the environmental, physiological and chemical factors associated with adventitious root formation in cutting, with up-to-date literature and lucid illustrations - Presents a multidimensional approach and a broad range of explanation on adventitious root formation associated with mature and juvenile cutting - Discusses a number of molecular, histological and physiological markers associated with adventitious root formation in numerous plant species - Elaborates on how external and internal factors control the cell/tissue initiation, differentiation and overall adventitious root formation in cutting

In this comprehensive book, plant biologists and environmental scientists present the latest information on different approaches to the remediation of inorganic pollutants. Highlighting remediation techniques for a broad range of pollutants, the book offers a timely compilation to help readers understand injury and tolerance mechanisms, and the subsequent improvements that can be achieved by plant-based remediation. Gathering contributions by respected experts in the field, the book represents a valuable asset for students and researchers, particularly plant physiologists, environmental scientists, biotechnologists, botanists, soil chemists and agronomists.

The sixth International Symposium on Genetics and Molecular Biology of Plant Nutriti9n was held in Elsinore, Denmark from August 17-21, 1998 and organised by th RiS0 National Laboratory in the year of its 40 anniversary. The 98 participants represented 23 countries and 80 scientific contributions with 43 oral and 37 poster presentations. The symposium addressed the molecular mechanisms, physiology and genetic regulation of plant nutrition. The Symposium brought together scientists from a range of different disciplines to exchange information and ideas on the molecular biology of mineral nutrition of plants. The symposium emphasised: • Bridging the gab between molecular biology, applied genetics, plant nutrition and plant breeding. • The development of methodologies to improve the efficiency and effectiveness of nutrition of plants • Quality of plant products. With sessions on: Nitrogen; Phosphorous; Micronutrients; Symbiosis; Membranes; Stress; Heavy Metals and Plant Breeding. In comparison with the previous conferences in this series more emphasis was placed on use of molecular techniques to clarify physiological mechanisms and processes, gene expression and regulation, as well as genetic marker assisted analysis. Significant of molecular genetic markers and other progress was reported in exploitation biotechnologies in breeding programmes.

We are living in the ocean of microbes. These tiny microorganisms are responsible for creating atmosphere for the present day life forms. These microorganisms have immense potential to fulfill the need of the human kind. They can provide us food, fuel, fertilizer. They act as a sequesters, remediators, scavengers, and what not. The recent era is the era of biotechnology once we equipped ourself with the modern technology. It is easy to harness the potential of different microorganisms for the benefit of human kind particularly clean environment, quality food and non fossilized fuel. The judicial exploitation of microorganisms with the help of biotechnological tools not only help us to keep our environment clean, pollution free, but also help us to conserve the diversity and ultimately to protect the planet earth from any undesirable conditions. The present volume is a compendium of wide ranging current topics on microbiology, biotechnology and ecology. It is an assemblage of up to date knowledge of recent advances and development taking place in the field of microbial biotechnology and ecology. The book is a unique compilation of 50 chapters. The book “Microbial biotechnology and ecology grouped in three sections 1- Microbiology, 2-Biotechnology and 3- Ecology. The microbiology section includes about 22 articles on bacteria, cyanobacteria, VAM fungi, mushrooms. The biotechnological section includes biotechnological potential of various microorganisms and plants. In this section overall 16 articles are included. In the ecological section articles based on general ecology, bioindicators, eutropication, aquatic biodiversity, pollution etc. This section comprises of about 12 articles. The book is assemblage of scientific information contributed by eminent scientists of the country in the form of commoration volume, to give a scientific tribute to a great Mycologist and Plant Pathologist late Prof. Dr. K.M. Vyas. Who has devoted his life for the dissemination of science and scientific knowledge particularlyin the field of microbiology and biotechnology.

Agroforestry is practiced traditionally since time immemorial to meet diverse needs of households and holds good prospects in present times also on account of global climate change and population pressure. At microlevel in farms, there are twin problems of getting and sustaining higher crop productivity vis-à-vis minimizing environmental impact and maintaining soil quality. These twin problems can get solved by developing and adopting site specific agroforestry systems. In the context, this book identifies the key issues associated with agroforestry practices for meeting challenges of sustaining high resource productivity, livelihood security with mitigation of climate challenge. It discusses solutions to these challenges by giving region specific agroforestry systems, manipulation of agroforestry knowledge for soil and water conservation and solving many issues in agroforestry. Topics covered include scope and practices of agroforestry, mitigation of climate change, manipulation of processes in agroforestry for better resource productivity, ecosystem development through agroforestry, issues in agroforestry research and development.
