Ferns, Robert H. Mohlenbrock

Illustrated Flora of Illinois

Perhaps no other group of plants attracts more interest among both professional and amateur botanists than ferns. As early as 1846, when one of the first lists of Illinois plants was published, sixteen species of ferns were already known in the state. The longtime interest of a great many people makes the distribution of ferns better known than that of any other group of plants in Illinois.

This detailed account of ferns and fern-allies was first published in 1967 as the first volume in the series The Illustrated Flora of Illinois. Eminent botanist Robert H. Mohlenbrock has now revised Ferns …

Herbicide Evaluation In Arkansas Rice, 1998, Ron Talbert, Ford Baldwin, David Gealy, Tomilea Dillon, Lance Schmidt, Eric Scherder, Celeste Wheeler, Leopoldo Estorninos Jr., Jeff Rutledge, Rebecca Chavez

Arkansas Agricultural Experiment Station Research Series

Weed control is economically important for production of rice, a major crop in Arkansas. These findings summarize efforts of the team of Arkansas scientists working on weed control strategies for rice during 1998. Various technologies were evaluated in field studies involving the major weed problems and rice production systems used in the state. Results from these studies will add to the arsenal of weed control options for producers. The preliminary results reported here generally warrant further testing for more advanced findings and for the labeling of new technologies and, finally, are the basis for updating safe, effective, and economical recommendations …

Review Of A Classification Of North American Biotic Communities By David E. Brown, Frank Reichenbacher, Susan E. Franson, Robert B. Kaul

Great Plains Research: A Journal of Natural and Social Sciences

This is the latest of many efforts over the past century to classify North America's natural, undisturbed biological communities as they existed in pre-agrarian times and in many places continue to exist today. Its authors' stated objective is to integrate existing works into a hierarchical synthesis that can lead to a standardized system for researchers, land managers, conservation groups, and government agencies. To that end, the authors have modified and expanded David Brown's earlier classification for the Southwest to cover the continent, defined here as the area from the Panama Canal to the Arctic, including Greenland and some of the …

Review Of Population Biology Of Grasses, Thomas B. Bragg

Biology Faculty Publications

Population Biology of Grasses provides a wealth of knowledge beyond population biology that ecologists and ecosystem biologists will find relevant to their concerns, particularly those with an interest in grasslands. Though not limited to the Great Plains region, the book would make an excellent addition to the reference shelf of anyone interested in grasses and grassland-related ecosystems, including readers with an interest in land management and preservation. While the papers are written for different levels of readers, all provide information accessible to non-specialists.

Mechanical Conditioning Of Tomato Seedlings Improves Transplant Quality Without Deleterious Effects On Field Performance, Lauren C. Garner, Thomas Björkman

Horticulture and Crop Science

Excessive stem elongation reduces plant survival in the field and hinders mechanical transplanting. Mechanical conditioning is an effective method for reducing stem elongation during transplant production. This investigation examined the consequences of mechanical conditioning, using brushing and impedance, on subsequent field performance of tomatoes (Lycopersicon esculentum Mill.). Mechanically conditioned transplants of processing tomatoes resumed growth after transplant shock as quickly as did untreated plants, and subsequent canopy development was also equal. In 4 years of field trials, yield was not reduced by mechanical conditioning. Transplants for fresh-market tomatoes may be more sensitive to injury than those for processing tomatoes because …

Modeling Surface And Subsurface Pesticide Transport Under Three Field Conditions Using Przm-3 And Gleams, Robert W. Malone, Richard C. Warner, Stephen R. Workman, Matt E. Byers

Biosystems and Agricultural Engineering Faculty Publications

Contaminant transport models should be evaluated over a wide range of conditions to determine their limitations. The models PRZM and GLEAMS have been evaluated many times, but few studies are available in which predicted movement in runoff and percolate were simultaneously evaluated against field data. Studies of this type are essential because pesticide leaching and runoff are mutually dependent processes. For this reason, PRZM-3 and GLEAMS were evaluated for their ability to predict metribuzin concentrations in runoff, sediment, subsurface soil, and pan lysimeters under three field conditions (yard waste compost amended, no-till, and conventional-till) on a Lowell silt loam soil. …

Sp307-O-Home Apple Cider Production, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Cider making is an art that is as old as apple production itself. When properly made, fresh apple cider is a safe, natural, delicious product that conjures up images of autumn and the country.

Apple cider is simply the liquid that is released when apples are crushed. It has nothing added and nothing taken away from it. Apple cider will be cloudy due to the presence of suspended apple solids. Since apple cider contains no preservatives, it has a limited shelf life, and special attention must be paid to proper storage. The terms apple cider and apple juice are often …

Biological Control Of Bipolaris Sorokiniana On Tall Fescue By Stenotrophomonas Maltophilia Strain C3, Z. Zhang, G. Y. Yuen

Department of Plant Pathology: Faculty Publications

Stenotrophomonas maltophilia strain C3 was evaluated for control of leaf spot on tall fescue (Festuca arundinacea) caused by Bipolaris sorokiniana. In growth chamber experiments, C3 inhibited conidial germination on leaf surfaces and reduced lesion frequency and percent diseased leaf area compared with nontreated controls. The amount of leaf spot suppression was related to the C3 dose applied. The highest dose tested, 10⁹ CFU/ml, prevented nearly all B. sorokiniana conidia from germinating on treated leaf surfaces and provided nearly complete suppression of lesion development. When colloidal chitin was added to C3 cell suspensions of 10⁷ or …

Gender Variation In Croton Californicus (Euphorbiaceae), James Lynwood Smith Ii

Loma Linda University Electronic Theses, Dissertations & Projects

Croton californicus Muell. Arg. (Euphorbiaceae) is a subshrub suspected of being dimorphic with phase choices. Gender variation in C. californicus was studied in natural populations of southern California for three years (1994-96) to observe patterns of gender !ability. Some sites exhibited significantly male-biased sex ratios, and these sites often had the greatest number of monoecious morphs, cosexual plants with unisexual flowers. Gender variation was quantified for cosexual plants by calculating the Estimated Floral Gender (EFG) which varied from 1.00 (female) to 0.00 (male). The distribution of the EFG was highly skewed towards maleness. Monoecious individuals were then categorized by …

An Integrated Genetic Linkage Map Of The Soybean Genome, P.B. Cregan, T. Jarvik, A.L. Bush, R.C. Shoemaker, K.G. Lark, A.L. Kahler, N. Kaya, T.T. Vantoai, D.G. Lohnes, J. Chung, James E. Specht

Department of Agronomy and Horticulture: Faculty Publications

A number of molecular genetic maps of the soybean [Glycine max (L.) Merr.] have been developed over the past 10 yr. These maps are primarily based on restriction fragment length polymorphism (RFLP) markers. Parental surveys have shown that most RFLP loci have only two known alleles. However, because the soybean is an ancient polyploid, RFLP probes typically hybridize and map to more than one position in the genome. Thus, the polymorphic potential of an RFLP probe is primarily a function of the frequency of the two alleles at each locus the probe detects. In contrast, simple sequence repeat (SSR) …

Pb819 Growing Vegetable Transplants In Tennessee, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

The production of vegetable plants for commercial and home use is increasing in Tennessee. This is partially due to the expansion of greenhouse flower and ornamental production. To meet the demand for home gardeners, growers have gradually added vegetable plants to their spring production operation. Growers are finding that production of quality plants is a profitable business in urban areas.

Successful vegetable plant production is not a simple practice, because it requires technical knowledge of production practices within an enclosed environment, careful planning and man age ment. Combining the required environmental conditions favorable for vegetable plant growth, either in a …
