Substrate production of blueberry : evaluation of soilless media and potassium, nitrogen fertility on growth and nutrition

Creator:: Kingston, Patrick H.
Abstract:: As blueberry (Vaccinium sp.) production has increased in recent decades, a new interest has developed in the cultivation of blueberry in soilless substrate containers. Historically, blueberry has been propagated and grown in soilless substrate at nurseries, but nursery production is short in duration and plants are small relative to a...

Overexpression of antioxidant genes in transgenic tomato tolerant against multiple stresses

Creator:: Wang, Yueju
Abstract:: The effect of increased manganese superoxide dismutase (Mn-SOD) and cytosolic ascorbate peroxidase (cAPX) on various abiotic stresses was studied using transgenic tomato (Lycopersicon esculentum) plants. Transformants were selected in vitro based on kanamycin resistance, confirmed by PCR and northern blot analyses. Northern blots showed an enhanced gene expression of Mn-SOD...

Breeding, Production, and Morphophysiology Among Cytotypes of Common and Portuguese Cherrylaurel

Creator:: Schulze, Justin A.
Abstract:: The common cherrylaurel (Prunus laurocerasus) and Portuguese cherrylaurel (P. lusitanica) are economically important landscape shrubs across the United States. To gain a better understanding of physiology and morphology in these higher level polyploids (P. lusitanica, 2n = 8x; P. laurocerasus, 2n =22x), a variety of breeding experiments were performed. The...

Effects of Biochar and Nitrogen-Enriched Soil Amendments on Plant Growth, Mineral Nutrition, and Early Fruit Production in Highbush Blueberry (Vaccinium sp.)

Creator:: Sales, Bryan K.
Abstract:: The goal of the work in this dissertation was to identify alternative soil amendments to improve plant growth and yield during establishment of highbush blueberry (Vaccinium hybrid). Woody materials, such as sawdust and wood chips, have a high carbon to nitrogen (C:N) ratio and low water holding capacity, which can...

Use of nondestructive spectroscopy to assess chlorophyll and nitrogen in fresh leaves

Creator:: Ding, Pinghai
Abstract:: Four aspects of factors influencing the accuracy of nondestructive chlorophyll (Chl) and nitrogen (N) measurement in fresh leaves were studied: (1) optimum wavelength (OW) identification; (2) indices development and evaluation; (3) influence of leaf properties; and (4) influence of meter parameters and sampling technique. Results were used to develop indices...

Evaluation of Methods for Applying Phosphorus, Potassium, and Boron Fertilizers in Northern Highbush Blueberry (Vaccinium corymbosum L.)

Creator:: Leon-Chang, David P.
Abstract:: Previous studies indicated that fertigating with nitrogen (N) was more effective than using granular N fertilizers in production of northern highbush blueberry (Vaccinium corymbosum L.). To build on these findings, four studies were conducted in western Oregon to determine whether fertigation was also an effective method for applying other nutrients,...

Factors affecting the incidence and severity of Phytophthora syringae cankers in pear (Pyrus communis) trees

Creator:: Laywisadkul, Srisangwan
Abstract:: Container grown pear trees were used to determine the effects of the following factors on the susceptibility to Phytophthora syringae: 1) tree nitrogen (N) status and foliar sprays of urea and copper-EDTA (CuEDTA); 2) dormancy and environmental conditions; 3) wound and wound age; and 4) chemical and biological control measures....

Improvement of cryopreservation regrowth of in vitro Ribes by pretreatment

Creator:: Luo, Jie, 1968-
Abstract:: Improved recovery of cryopreserved meristems and calli from in vitro currant (Ribes aureum Pursh and R. ciliatum Humb. & Bonpl.) plants was obtained by two-hour pretreatment with sucrose, proline, abscisic acid-responsive protein (RABP), and bovine serum albumin (BSA) solutions. Meristems and calli cold-acclimatized for one week were immersed in pretreatment...

Effects of Irrigation Frequency and Nitrogen Fertilizer Rate on Water Stress, Nitrogen Uptake, and Plant Growth of Container-grown Rhododendron

Creator:: Scagel, Carolyn F., Bi, Guihong, Fuchigami, Leslie H., and Regan, Richard P.
Abstract:: The influence of irrigation frequency (same amount of water per day given at different times) and nitrogen (N) fertilizer rate on water stress [stomatal conductance (gs)], N uptake, and growth (biomass) of container-grown evergreen Rhododendron 'P.J.M. Compact' and 'English Roseum' and deciduous Rhododendron 'Gibraltar' was evaluated. Both N deficiency and...
