Honeybees and Wax: An Experimental Natural History
ISBN: 9783642714603 / Angielski / Miękka / 205 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. "Instead of dirt and poison we have rather chosen to fill our hives with honey and wax; thus furnisning mankind with the two noblest of things, which are sweetness and light." Mindful of Swift's dictum, this compilation is offered as an exhaustive coverage of a smallish literature on the synthesis and secretion of beeswax, its elaboration into combs and the factors which bear on the execution of these processes by honeybees. To codify any aspect of the biology of an animal of agricultural importance is to sift through myriad observations and experiments, centuries old, that come down to us...

Frost Survival of Plants: Responses and Adaptation to Freezing Stress
ISBN: 9783642717475 / Angielski / Miękka / 321 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Low temperature represents, together with drought and salt stress, one of the most important environmental constraints limiting the pro- ductivity and the distribution of plants on the Earth. Winter survival, in particular, is a highly complex phenomenon, with regards to both stress factors and stress responses. The danger from winter cold is the result not only of its primary effect, i. e. the formation of ice in plant tissues; additional threats are presented by the freezing of water in and on the ground and by the load and duration ofthe snow cover. In recent years, a number of books and...

Juvenile Wood in Forest Trees
ISBN: 9783642721281 / Angielski / Miękka / 304 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The trend in forestry is toward shorter rotations and more complete utiliza tion of trees. The reasons are: (1) financial pressures to obtain rapid returns on the forestry investment made possible by an earlier harvest; (2) enforced harvest of young plantations to maintain a continuing supply of cellulose for mills where wood shortages are experienced; (3) thinning young plantations, both because they were planted too densely initially and because thinning is done where long rotation quality trees are the forestry goal; (4) more intensive utilization is being done using tops and small...

Vascular Differentiation and Plant Growth Regulators
ISBN: 9783642734489 / Angielski / Miękka / 154 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The main objective of the book is to provide an up-to-date examination of the possible roles of plant hormones during the cytodifferentiation of xylem and phloem elements in higher plants. Various facets of vascular differentiation, as cell determination, cell cycle activity, and the biochemical events in xylogenesis, are analyzed. Furthermore, the latest information on the roles of auxins, cytokinins, gibberellins, ethylene, and abscisic acid during vascular cell formation are summarized. A theoretical discussion of the six-point hypothesis and the vascular adaptation hypothesis is included....

Postharvest Biotechnology of Flowers and Ornamental Plants
ISBN: 9783642738050 / Angielski / Miękka / 192 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The floricultural industry has been undergoing an unprecedented revolu tion in terms of the type of commodity produced and the production and marketing technology in both developed and developing countries. As a result of this revolution, as we know today, there is a flower for every purpose and for every person in the world, as is evident from the slogan of the Society for American Florists: "say it with flowers." In re cent years, the Latin American and European countries have become sizeable competitors for the North American fresh flower markets and the trend continues growing. Like any...

Utilization of Residual Forest Biomass
ISBN: 9783642740749 / Angielski / Miękka / 568 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. An increase in the demand for wood results in improved recovery and less residual biomass in the forests. Paradoxically, interest in forest residue as a renewable source of raw material seems to be in a reverse ratio to its availability in a certain area. Finland and Sweden are probably more dependent on forestry and forest in dustries than any other developed countries in the world. A sufficiency of raw ma terial for integrated forest industries is vital for the national economy of both countries, and a great deal of attention is being paid to the long-term potential of unutilized biomass...

Recognition and Response in Plant-Virus Interactions
ISBN: 9783642741661 / Angielski / Miękka / 467 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Mechanisms of resistance to plant viruses are diverse, and probably involve different types of recognition events. Often, a cascade of changes affecting broader aspects of defence and metabolism is switched on progressively after the initial recognition event. Virulence, i.e. resistence-breaking behaviour of the virus, involves a failure or alteration of recognition or subsequent signalling. Consequences of these recognition events are the ways in which the pathogenic effects on the host are exerted: formation of visible symptoms and control of plant growth. This volume offers a comprehensive...

Forest Dynamics: Silvi-Star: A Comprehensive Monitoring System
ISBN: 9783642750144 / Angielski / Miękka / 229 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. No matter what forests are used for, forest managers have to deal with interactions between individual trees and between trees and other forest organisms. To understand these interactions, long-term monitoring of spontaneous forest development is necessary. A complete monitoring system has been developed including a computer package for analysis of long-term observation of forest dynamics. The system's name, "SILVI-STAR," is an acronym of SILVIgenesis and Single-tree Three-dimensional Architecture. A method of nested plot data collection on forest architecture and plant species composition...

Agricultural, natural resource, and environmental problems are becom ing increasingly interdependent. For example, soil erosion is largely determined by agricultural land use. Both water use and water con tamination depend on land use and technology choice in agriculture. In many areas, the fertilizers and pesticides used in agriculture are ma jor pollutants of ground and surface water, having adverse effects on drinking water and fisheries. Agricultural pollutants such as pesticides also produce adverse health effects for agricultural workers and the consuming public. On the other hand, the...
