Available in PDF, EPUB and Kindle. Book excerpt: There is an increasing need for development of laboratory identification procedures for purposes of plant variety protection, seed certification, quality control and consumer protection. In the past there were fewer commercial varieties and field testing methods based on morphological differences were used satisfactorily. These tests require several months to complete and are subsequently of limited practical use. With the large number of current varieties, visual differences are much smaller and the task of identification is increasingly difficult. This study was initiated to investigate various morphological, chemical and biochemical characteristics of 25 varieties grown in the Pacific Northwest. The five tests described in this study provide the basis for a laboratory identification system for these varieties. The coleoptile color test was of limited value for these varieties, since only Golden exhibited a purple coleoptile while the remaining varieties were green. The seedling pubescence test separated the varieties into two groups: slightly pubescent and pubescent. However, the variation of the pubescence density caused by environmental conditions limits its practical use. The phenol test separated the varieties into three distinct groups: Light Brown, Brown, and Mixed. Four varieties, Barbee, Daws, Druchamp, and Luke, exhibited a mixed phenol reaction. This mixture was characteristic of these varieties since they were uniform for the other characters. Esterase, catalase, acid phosphatase and glutamic oxaloacetic transaminase were not useful for separating the varieties since all of them developed similar banding patterns for each enzyme. Peroxidase electrophoresis separated the varieties into two distinct groups on the basis of the presence or absence of a single band. Gliadin electrophoresis was the most discriminating test, distinguishing all the varieties except for those genetically closely related. These included varieties within three variety groups: Gaines and Nugaines; Fielder and Fieldwin; and Hyslop, Hill, McDermid, and Stephens. The phenol test provided a useful separation of the group of four varieties which were uniform for gliadins. Hill and Hyslop developed a brown phenol stain while McDermid and Stephens exhibited a light brown stain. Further identification might be possible by other means, such as pathogen resistance, isoelectric focusing and other chemical tests. In practice, unknown samples should be compared to authentic, standard samples for final identification.

Download or read book Australian Wheat Varieties written by RW Fitzsimmons and published by CSIRO PUBLISHING. This book was released on 1983-06-01 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides a practical description of wheat grain, heads and plants at several growth stages. It is designed to assist in distinguishing varieties currently grown throughout Australia, in the regions where each is usually grown. It is directed at a broad audience, including those involved with the grain trade at all stages, from seed production, through growing and harvesting, to receival and segregation, sales and utilization. Although Australia-wide in its overall approach, it is hoped that the handbook will form a basis to meet specialised local needs. Thus smaller sets of sheets, relating to local groups of varieties, might be selected and additional comments added, in the space provided, relating to the particular locality and season. In such a case, the characters that show the greatest differences between the particular varieties should be selected for identification.

Download or read book Australian Barleys written by RW Fitzsimmons and published by CSIRO PUBLISHING. This book was released on 1984-06-01 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides a basis for checking the range of quality factors that can be judged by on-the-spot examination. When barley is being received at the silo or the malt-house, it is impractical and unnecessary to use the range of precise laboratory methods devised for quality testing, although these can be used to decide about border-line samples or to resolve disputes. Instead, an approximate indication of many quality factors can be obtained by visual examination to determine: (a) the variety, to make sure that the load is binned with other barley of a compatible quality type; (b) the extent of damage to grains, as an indication of how satisfactory the grain will be for the particular use for which it is offered; (c) the degree of contamination with foreign seeds, to determine the purity of the barley, the expense involved in cleaning it and its suitability for use as human or animal food depending on the toxicity of the contaminants. In addition to these three aspects of quality, there are other factors such as test weight and protein content that can be measured on receival of grain, but they are beyond the scope of this book.
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: Modern Methods of Plant Analysis When the handbook Modern Methods of Plant Analysis was first introduced in 1954 the considerations were: 1. the dependence of scientific progress in biology on the improvement of ex isting and the introduction of new methods; 2. the difficulty in finding many new analytical methods in specialized jour nals which are normally not accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently so compact, or even sometimes so incomplete that it is dif ficult to reproduce experiments. These considerations still stand today. The series was highly successful, seven volumes appearing between 1956 and 1964. Since there is still today a demand for the old series, the publisher has decided to resume publication of Modern Methods of Plant Analysis. It is hoped that the New Series will be just as acceptable to those working in plant sciences and related fields as the early volumes undoubtedly were. It is difficult to single out the major reasons for success of any publication, but we believe that the methods published in the first series were up-to-date at the time and presented in a way that made description, as applied to plant material, com plete in itself with little need to consult other publications. Contribution authors have attempted to follow these guidelines in this New Series of volumes.
Download or read book Australian Oat Varieties written by RW Fitzsimmons and published by CSIRO PUBLISHING. This book was released on 1983-06-01 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to provide the means of identifying oat varieties so that maximum advantage is obtained from the breeders' efforts by ensuring that the correct variety of grain is planted and delivered. The book is intended for use by those involved at all stages of the oat industry, from breeding and seed production, through growing and harvesting, to receival and segregation, marketing and utilization. Descriptions of the growing plant, panicle and grain are provided to permit identification at any point throughout the life cycle. Despite the biological variation to be expected in the shape and size of a population of grains or panicles of any particular variety, there is still a characteristic uniformity that distinguishes one variety from another. In a sense these differences defy dissection and description, as they are part of an overall impression gained by experience. However, the descriptions and illustrations in this book are provided to draw attention, in a systematic way, to these differences and to provide an aid to the gaining of experience in identification. The term 'variety' is used throughout, because of its general usage, in preference to the scientific word I cultivar.
