Influence of ethylene treatments or ethephon dips on bulbous iris forcing

Creator:: Cascante Herrera, Xenia
Abstract:: A series of 3 experiments was conducted from 1984 to 1986 to determine the influence of ethylene gas treatments and ethephon [(2-chloroethyl) phosphonic acid] dips, in combination with several heat curing durations, on the performance of greenhouse-forced Blue Ribbon and Ideal iris. In the first study which examined the effects...

Breeding Snap Beans for Organic Agriculture: Quantification and Application of Key Traits

Creator:: Park, Hayley E.
Abstract:: Improving crop cultivars for use on organic farms is pertinent, as current elite germplasm is less resilient within the more variable context of organic farm environments. Although a growing number of studies have focused on organic plant breeding in cereal crops, very few have focused on vegetable crops, especially those...

Phylogenetic Estimation and Ancestral State Reconstruction of Rubus (Rosaceae) using Target Capture Sequencing

Creator:: Carter, Katherine A.
Abstract:: Hybridization, polyploidy, and apomixis have made phylogenetic estimation in Rubus challenging. I used target capture to sequence approximately 1000 low copy nuclear loci and the chloroplast genome for 94 accessions representing the genus Rubus and distributed worldwide. Species phylogenies were estimated using two coalescent based methods, ASTRAL-II and SVDQuartets, and...

Validation of Molecular Markers Associated with Perpetual Flowering (PF) and Soluble Solids Content (SSC) in Strawberry (Fragaria xananassa Duch. ex Rozier)

Creator:: Salinas, Natalia R.
Abstract:: Strawberry is economically the most important berry crop grown worldwide and breeders are continuously striving to develop improved cultivars. So far, marker assisted breeding (MAB) in strawberry has been limited to the private sector. However, loci controlling some traits of economic importance such as perpetual flowering (PF) and soluble solids...

Zeatin O-xylosyltransferase in Phaseolus vulgaris : immunological and molecular analyses

Creator:: Martin, Ruth C.
Abstract:: Cytokinins are a group of plant hormones mediating cell division and differentiation. Zeatin is a naturally occurring and highly active cytokinin that is rapidly metabolized in Phaseolus seeds. The metabolites and enzymes mediating the conversion have been studied extensively. Zeatin metabolic enzymes may be utilized in studying the regulation of...

Somaclonal variation, regeneration and transformation of quince (Cydonia oblonga Mill.) and pear (Pyrus communis L.)

Creator:: Bunnag, Sumonthip
Abstract:: Quince (Cydonia oblonga Mill.) is widely used as a dwarfing rootstock for pear {Pyrus communis L.). The disadvantage of this rootstock is its inefficient uptake of Fe, resulting in leaf chlorosis. Application of tissue culture and gene transfer techniques may lead to production of quince clones with improved Fe efficiency....

Behavior of Drosophila suzukii in Relation to Abiotic, Biotic, and Nutrient Factors

Creator:: Park, Kyoo Rok
Abstract:: Drosophila suzukii (Diptera: Drosophilidae), is a serious pest in soft and stone fruit industries worldwide. The unique serrated ovipositor of female Drosophila suzukii allowed the species to reproduce in intact, ripening fruit before the harvest. Current control methods rely heavily on insecticide application, only becoming less profitable due to the...

Enhancement of the weed competitive ability of lowland rice (Oryza sativa L.) cultivars

Creator:: Ranasinghe, Lakshman L.
Abstract:: Most of the presently grown cultivars of rice (Oryza sativa L.) have poor competitive ability against weeds if compared with traditional cultivars. Therefore, effective weed control is an important but often costly and difficult management practice in rice crop production. If weed competitive ability of rice cultivars could be improved...

Effects of Diet and Humidity on Drosophila suzukii Flight Performance

Creator:: Wong, Jessica S.
Abstract:: Drosophila suzukii is a global and economically significant pest of berries and other soft fruits. This insect can survive and reproduce under a wide variety of environmental conditions and with a substantial number of cultivated and wild hosts. Management of D. suzukii is commonly done with chemical control strategies. However,...

Facilitating plant-parasitic nematode management decisions for Washington Vitis vinifera growers : determining the spatial distribution of plant-parasitic nematodes and the host status of Vitis spp. to Meloidogyne hapla

Creator:: Howland, Amanda D.
Abstract:: A major constraint to the production of self-rooted wine grapes (Vitis vinifera) in eastern Washington is plant-parasitic nematodes. Plant-parasitic nematodes can impact grape productivity by limiting water and nutrient uptake, educing physiological changes, and extracting plant nutrients from roots, thereby reducing root biomass, plant vigor, and yield. The most commonly...
