Sunlight And Plants, Some Pursuits In Physiological Ecology, Martyn M. Caldwell
Sunlight And Plants, Some Pursuits In Physiological Ecology, Martyn M. Caldwell
Faculty Honor Lectures
A physiological ecologist, as the name suggests, focuses on the interface between plant physiology and the ecology of individual organisms. Yet, one in this field should know something about disciplines ranging from physiology, or in the case of the subject of this lecture, even photochemistry, to the study of entire ecosystems.
Isolation Of A Collagenase Cdna Clone And Measurement Of Changing Collagenase Mrna Levels During Induction In Rabbit Synovial Fibroblasts., Robert H. Gross, Lynn A. Sheldon, Colin F. Fletcher, Constance E. Brinckerhoff
Isolation Of A Collagenase Cdna Clone And Measurement Of Changing Collagenase Mrna Levels During Induction In Rabbit Synovial Fibroblasts., Robert H. Gross, Lynn A. Sheldon, Colin F. Fletcher, Constance E. Brinckerhoff
Dartmouth Scholarship
To facilitate our studies on the mechanisms controlling collagenase production at a molecular level in rabbit synovial fibroblasts, we have constructed a cDNA library using mRNAs isolated from cells induced with crystals of monosodium urate monohydrate. We have screened this library with cDNA probes made from induced and control mRNA populations. From among 30 clones that hybridized preferentially to the induced-cell probe, 4 contained collagenase sequences. The largest, a clone of 650 base pairs, was identified by its ability to hybrid select a mRNA that could be translated in a cell-free system into a product that was precipitable with monospecific …
G84-725 Measuring Harvest Loss Of Dry Edible Beans, John A. Smith
G84-725 Measuring Harvest Loss Of Dry Edible Beans, John A. Smith
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide describes how to measure losses before, during and after harvest operations, so that problems can be corrected and losses reduced. Harvesting dry edible beans in Nebraska normally includes three separate field operations--cutting, rodding or windrowing, and combining--over a period of three to seven days. The success of these operations is very dependent on equipment selection and adjustment, weather and field conditions, and operator skill.

G84-698 Selecting A Ground Cover (Revised July 1999), Anne Streich, Don Steinegger
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide describes how to evaluate a site for ground cover and the characteristics of the most common ground cover species grown in Nebraska.
Ground covers are low-growing plants used in landscaping for mulching or covering the soil. They are typically low growing but may range in height from just inches to over 4 feet tall. Ground covers differ in color, texture and form and can be herbaceous, woody, succulent or grassy. Some have attractive flowers, while others are grown only for their foliage.
Selecting the best species for a site is important to its success as a ground cover. …
Seasonal Shifts Of Photosynthesis In Portulacaria Afra (L.) Jacq., Lonnie J. Guralnick, Patricia A. Rorabaugh, Zac Hanscom
Seasonal Shifts Of Photosynthesis In Portulacaria Afra (L.) Jacq., Lonnie J. Guralnick, Patricia A. Rorabaugh, Zac Hanscom
Arts & Sciences Faculty Publications
Portulacaria afra (L.) Jacq., a perennial facultative Crassulacean acid metabolism (CAM) species, was studied under natural photoperiods and temperatures in San Diego, California. The plants were irrigated every fourth day throughout the study period. Measurements of 14CO2 uptake, stomatal resistance, and titratable acidity were made periodically from July 1981 through May 1982. P. afra maintained C3 photosynthesis during the winter and the spring. Diurnal acid fluctuations were low and maximal 14CO2 uptake occurred during the day. The day/night ratio of carbon uptake varied from 5 to 10 and indicated little nocturnal CO2 uptake. CAM …

G84-697 Ground Covers: Their Establishment And Maintenance (Revised June 1992), Don Steinegger, Luann Finke
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide describes how to plant and maintain ground covers to take advantage of their low-maintenance features.
Ground covers are low-growing plants, usually less than 12 inches tall, that spread to form dense mats which bind and hold the soil in place. Many also have a season of effective bloom. Turfgrass is the most common ground cover. However, sites that are less suitable for turfgrass, such as slopes, steep banks, and shaded areas, can often grow other ground covers successfully.
A well-established ground cover generally requires less maintenance than the typical turfgrass lawn. Ground covers are not totally maintenance-free, nor …
