Nitrogen, defoliation and new growth in almond (Prunus dulcis (Mill) D.A. Webb) nursery plants

Creator:: Bi, Guihong
Abstract:: The relationships between nitrogen (N), defoliation, and plant growth in nursery plants were studied using almond {Prunus dulcis (Mill) D. A. Webb) trees. In several experiments the effects of N source and availability on tree growth, N uptake, N remobilization, and nonstructural carbohydrates (TNC) were investigated to determine the most...

The effects of planting date, nitrogen and boron application on mineral element concentration, yield, dry weight and fresh weight of sweet corn

Creator:: Sisson, Jonathan Anthony
Abstract:: The effects of planting date on mineral element concentration in sweet corn (Zea mays L. cv. Jubilee) at six developmental stages and on yield were investigated. Planting dates were chosen to correspond to early, mid-season, and late commercial plantings. Two nitrogen rates were applied since nitrogen is more often limiting...

Quantitative Trait Loci and Genome Wide Association Study for Resistance to White Mold in Common (Snap) Bean.

Creator:: Arkwazee, Haidar A.
Abstract:: This is a Ph.D. dissertation for a study conducted at OSU/Horticulture. The main objective of this study was dissecting the genetic background for white mold resistance in common (snap) bean. Tow main approaches were followed to achieve the goal. The first approach was using the classical quantitative trait loci (QTL)...

Physiology of ripening in pears

Creator:: Wang, Chien Yi
Abstract:: Investigations were conducted to study in detail some biochemical and physiological aspects of ripening in pears. Anjou pears picked at different degrees of maturity were treated with Ethrel (2-chloroethane phosphonic acid), 4000 ppm, and ethylene, 500 ppm, for different lengths of time. Respiration rate was measured twice daily and changes...

Breeding an open pollinated broccoli for organic production systems using participatory methods

Creator:: McKenzie, Laurie R.
Abstract:: Organic agriculture is an important and growing sector of U.S. and world food production. Consumers are increasingly aware of and interested in the production practices and impacts associated with agriculture and as such, are showing a preference for sustainably produced, raised, and harvested foods. In order to continue to meet...

Boron nutrition and fruit set of 'Italian' prune

Creator:: Hanson, Eric J.
Abstract:: Foliar B sprays have increased fruit set in 'Italian' prune (Prunus domestica L.) by 2 fold in some trials and had no effect in others. This work was conducted to identify reasons for this inconsistent response. Since B levels in flowers are associated with the amount of fruit set, factors...

Influence of nitrogen form ratio and calcium on greenhouse and field performance of watermelon

Creator:: Lamb, Michael J.
Abstract:: Watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai var. Crimson Sweet) was seeded in a commercial peat mix in multicell containers (72 cells-tray⁻¹, 40 cm³-cell⁻¹) in July 1989 and April 1990. In 1989, the medium was amended with CaC0₃ at 10% w:v. In 1990, no CaC0₃ amendment was made. Watermelon seedling...

Fall applied ethephon and temperature effects on flower bud growth and ovule longevity in Prunus domestica

Creator:: Moreno-Simunovic, Yerko M.
Abstract:: In the Pacific Northwest some prune cultivars often exhibit inconsistent fruit set. Several factors have been associated with this characteristic. Temperature, genotype and boron content are among the most frequently mentioned. Studies were conducted to determine the effect of fall ethephon application on flower bud growth and ovule longevity in...
