(Kerry Ann) Ward and published by National Library of Canada = Bibliothèque nationale du Canada. This book was released on 1990 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: High levels of chlorophyll in harvested canola seed cause an increase in processing costs, lower returns for producers and poorer quality end products. The effects of genotype, environment and agronomic practices on seed chlorophyll levels were investigated in this study. When canola seed was frozen for up to one month, either in the pods or after removal, no significant reduction in chlorophyll was observed. Results from a swathing study indicate that seeds from the side branches contained 1.5 to 2 times as much chlorophyll as seeds from the main stems. Seed that was dried rapidly contained 1.5 to 6 times as much chlorophyll as seed allowed to mature in swaths in the field. When seeds from each treatment in the swathing study were subdivided according to size, the smallest seeds were found to contain the most chlorophyll. Seed from the treatments with the highest chlorophyll levels also contained the greatest amount of small seed. Chlorophyll degradation rates were investigated in four cultivars of Brassica napus as the seed ripened. No significant differences in the rate of chlorophyll breakdown were found between the different cultivars tested. Cultivars that require longer growing seasons to reach maturity were found to initiate seed chlorophyll degradation later in the growing season, increasing the chances that high levels will remain when the seed is harvested. The environment did affect the rate of chlorophyll degradation, as slower breakdown rates did occur in later sown plots. This was assumed to be due to the lower daily mean temperatures which occured later in the growing season. A number of cultivars of both B. napus and B. campestris grown at sites throughout Manitoba were measured for seed chlorophyll levels at harvest. No significant differences were found among different cultivars of B. campestris but the final chlorophyll levels of B. napus seed were extremely variable, both among triazine tolerant cultivars and those without triazine resistance. The environment also affected the seed chlorophyll level and there was a significant genotype by environment interaction. Seed samples of a number of cultivars taken from high chlorophyll sites were subdivided according to size and the smallest seeds were found to contain the most chlorophyll. The relationship between the percentage of small seed in any sample and the chlorophyll level was less defined in the "Agroman" material than in the swathing study.

This book was released on 2009-08-25 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an ever-increasing human population, the demand placed upon the agriculture sector to supply more food is one of the greatest challenges for the agrarian community. In order to meet this challenge, environmentally unfriendly agroch- icals have played a key role in the green revolution and are even today commonly recommended to circumvent nutrient de?ciencies of the soils. The use of ag- chemicals is, though, a major factor for improvement of plant production; it causes a profound deteriorating effect on soil health (soil fertility) and in turn negatively affects the productivity and sustainability of crops. Concern over disturbance to the microbial diversity and consequently soil fertility (as these microbes are involved in biogeochemical processes), as well as economic constraints, have prompted fun- mental and applied research to look for new agro-biotechnologies that can ensure competitive yields by providing suf?ciently not only essential nutrients to the plants but also help to protect the health of soils by mitigating the toxic effects of certain pollutants. In this regard, the role of naturally abundant yet functionally fully unexplored microorganisms such as biofertilizers assume a special signi?cance in the context of supplementing plant nutrients, cost and environmental impact under both conventional practices and derelict environments. Therefore, current devel- ments in sustainability involve a rational exploitation of soil microbial communities and the use of inexpensive, though less bio-available, sources of plant nutrients, which may be made available to plants by microbially-mediated processes.

Available in PDF, EPUB and Kindle. Book excerpt: Heavy metals are severe environmental pollutants, and many of them are toxic even at very low concentrations. With industrial development, soil pollution with heavy metal elements have dramatically increased. The uptake of heavy metals via plants that are exposed to contaminated soils is a risk for human health and a major hazard for the ecosystem as a whole, including soil microorganisms. On the other hand, plants may be used in the decontamination of soils. The topics presented in this book include: sources of heavy metals contaminants in soils; plant species that can grow on contaminated soils; the phytoremediation of contaminated soils; tolerance, accumulation and detoxification mechanisms of zinc, copper, arsenic, cadmium and vanadium in plants; the critical role of sulfur metabolism in heavy metal tolerance; the role of aquatic macrophytes, plant growth-promoting bacteria, sugar crops and earthworms in detoxification; and heavy metal stabilization by promoting zeolite synthesis in soils.

Available in PDF, EPUB and Kindle. Book excerpt: Chemical pest control is in use in practically every country in the world since agrochemicals play a decisive role in ensuring food supply and protection against damage by pests, insects and pathogenic fungi. Particularly in the half century since World War II, food production has risen dramatically in most parts of the world. In the last 20 years, the yield of major crops has roughly doubled in Western agriculture and there is still the potential for further achievements, particularly in the developing countries. The world's cereal and rice production, now more than 2 billion tons/year, has to increase by 2. 4% annually to cope with the rising food demand caused mainly by the growing population and improvement of living standards in most of the developing countries. Such a demand for food has to be achieved by higher yields from the restricted arable land already in use. Global farm land resources are about 1. 4 billion ha, of which 1. 2 billion ha is cultivated with major crops. Experts agree that a future substantial addition of new produc tive areas is unlikely. Those with a high yield potential are already in use; new fields with a lower output may possibly be obtained by cultivation of arid or cold areas. More recently, new areas of large-scale farmland have been devel oped in tropical regions of Latin America, primarily in Argentina and Brazil, at the cost of the destruction of tropical rain forest.

Book excerpt: There is growing enthusiasm in the scientific community about the prospect of mapping and sequencing the human genome, a monumental project that will have far-reaching consequences for medicine, biology, technology, and other fields. But how will such an effort be organized and funded? How will we develop the new technologies that are needed? What new legal, social, and ethical questions will be raised? Mapping and Sequencing the Human Genome is a blueprint for this proposed project. The authors offer a highly readable explanation of the technical aspects of genetic mapping and sequencing, and they recommend specific interim and long-range research goals, organizational strategies, and funding levels. They also outline some of the legal and social questions that might arise and urge their early consideration by policymakers.
