Studies in Blackberry: Development and Implementation of a Phenotyping Protocol for Blackberry Seedling Populations and Impact of Time of Day of Harvest on Red Drupelet Reversion for University of Arkansas Blackberry Genotypes
… at UA and implemented for two years on UA seedling populations. The protocol included plant traits (health, vigor, estimated crop load, peak bloom date, and number of canes) and fruit compositional traits (firmness by compression, berry weight, soluble solids content, pH, and titratable …

Inheritance of resistance to Rhynchosporium secalis (Oud.) J.J. Davis in Barley
… resistance at loci other than in Hudson. The F2 seedling populations from these crosses were studied in the greenhouse at Blacksburg in the early spring of 1960 and the winter of 1961.

Subalpine Forest Tree Seedling Response to Drought
… dynamics with climate change, especially at the seedling stage given their role in shaping forest structure. We used precipitation reduction shelters to mimic drought for subalpine conifer seedlings (<em>A. lasiocarpa</em> and <em>P. engelmannii</em>) in the Rocky Mountains and compared …

Creeping bentgrass response to plant growth regulating substances and annual bluegrass competition
… 1I plant growth regulator application, following seedling emergence reduced creeping bentgrass seedling populations. Competition from established annual bluegrass and close frequent cutting were deemed reasons for lack of creeping bentgrass establishment success. Creeping bentgrass turf was …

Impact of carbofuran on spring-seeded alfalfa and associated insect pests
… resulted from carbofuran application to alfalfa seedlings grown in a growth chamber using plastic pouches. High rates of carbofuran produced toxicity symptoms, reduced growth and increased protein content of plants. No-till alfalfa was seeded with granular carbofuran into a cereal rye cover crop …

Improvement of asexual propagation and Anisogramma anomala detection protocols to facilitate applied breeding of new Corylus avellana and C. americana x C. avellana germplasm
… that provide early detection of EFB susceptible seedlings would greatly improve the capacity and pace of cultivar development. This thesis focuses on ways to increase breeding efficiency by improving: 1) protocols used to propagate stem cuttings and, 2) early detection of EFB susceptibility in …

The influence of ryegrass sowing rates and nitrogen fertiliser on white clover establishment : A dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours at Lincoln University
… 3 kg/ha in all plots. Ryegrass and white clover seedling development, herbage production, botanical composition, herbage nitrogen percentage and grazing preference of autumn sown pastures were assessed. There was no advantage in terms of dry matter production from sowing greater than 10 kg/ha. …
