    Abstract: This book focuses on green nanoremediation addressing aspects related to the use of nanomaterials generated through green synthesis protocols to efficiently restore polluted environs. Nanomaterials’ characteristics such as large surface area, capacity to easily reach into contaminated sites, good reactivity, and possibility of being developed to present photocatalytic activity and/or to deal with targeted substances by chemical surface modification are useful specially to perform remediation. As an alternative to conventional physicochemical methods, the green-based synthesis protocols reject the use of harmful reagents, prevent waste production, apply renewable energy source and/or materials, and consider in first place offering the smallest negative impact possible to living beings and to the ecosystem. Green synthesis in nanotechnology field involves the use of seaweeds, bacteria, cyanobacteria, yeasts, fungi, plants (living ones, biomass, extracts) and/or bio-derived products to generate the nanomaterials. The introductory chapter will be dedicated to nanomaterials’ characteristics that enable them to be used in environmental remediation. The first part of the book will be dedicated to organic and inorganic pollution and the threats they pose to living forms; advantages, disadvantages and mechanisms of nanoremediation; comparison between conventional strategies of environmental pollution remediation and the green nanoremediation; carbon-based and non-carbon-based green nanomaterials capable of promoting environs’ remediation; cost/benefits of using nanomaterials and nanoinformatics to a safe nanotechnology. The second part will be dedicated to green nanoremediation of water and soil, microbe-based, algae-based and plant-based synthesis of nanomaterials to nanoremediation. This part will also contain chapters dedicated to relevant nanomaterials for green nanoremediation protocols, nano-phytoremediation strategies, strategies to evaluate the efficiency of protocols related to this kind of remediation, main interactions of green nanomaterials and microbes during nanoremediation and, as a consequence of it, biocompatibility of green nanomaterials. This book’s main purpose is to offer readers extensive knowledge on green nanoremediation as a feasible strategy to fight pollution's harmful consequences and clean environmental pollution, but also present the challenges that should be surpassed.

    Notes: Abstract The drought tolerance of the commercial apple ( Malus domestica Borkh.) rootstocks M9, M26, M27 and MM111, and some new selections from the rootstock breeding programme at HRI-East Malling (AR69-7, AR295-6, AR360-19, AR486-1 and AR628-2), was assessed using potted, glasshouse-grown, unworked rootstocks. After an initial period of growth under well-watered conditions the amount of irrigation was gradually reduced, for some treatments, to simulate natural drying in the soil. At the end of a six-month growth period, the rootstocks were harvested and the production of dry matter and its partitioning to various plant parts determined. The rootstocks exhibited large differences in shoot and root dry matter, and root length but not all the rootstocks showed declines in root mass or length in response to the droughting treatment. The dwarfing rootstocks tended to have smaller amounts of both coarse (〉2 mm diameter) and fine roots (〈2 mm diameter), than the more vigorous rootstocks. Irrespective of rootstock or irrigation treatment there was a close linear relationship between coarse and fine root. There was also no change in the length/weight relationship for fine roots irrespective of rootstock or irrigation treatment, i.e. 42 m of fine root weighed 1 g dry weight. In some cases the amount of root produced could be directly correlated with the rootstock known potential to control scion vigour, but this was not true for all the rootstocks examined. The absence of this relationship was particularly evident in some of the new selections of rootstock. The possible causes for these differences, compared with commercially used rootstocks, is discussed in relation to the origin and parentage of the rootstock selections. Despite this lack of a root length/vigour relationship, the amount of dry matter partitioned to shoot growth reflected the rootstocks' known vigour. The different responses of these rootstocks to drought are discussed along with their implications for understanding the mechanisms by which rootstocks are thought to dwarf scion shoots.
