A discussion about cold hardiness and effective plant protection strategies to minimize cold damage. The Oregon State University affiliated author addresses how plants become cold hardy, stages of hardiness, and effective protection.
Researchers evaluate selections from this sometimes underappreciated genus of landscape shrubs. Specific topics discussed in the article include landscape performance, disease resistance, and developing sterile cultivars.
This study on interspecific hybridization in Tecoma Juss. was conducted to develop novel forms for the nursery industry. The selection of species used in the study included T. garrocha, T. stans, T. guarume, and T. capensis.
Oregon State University professor Ryan Contreras discusses the Nursery Crop Breeding Program at OSU and the current research being conducted into woody landscape cultivars with reduced invasive potential, increased disease resistance, and increased abiotic stress tolerance.
Plant trials featuring Arctostaphylos and Grevillea varieties were conducted at Oregon State University North Willamette Research and Extension Center (NWREC). The purpose of the trials was to evaluate the plants performance in the landscape.
Research was conducted to determine the persistence of Metarhizium anisopliae (F52), measured as infectivity against black vine weevil larvae, in a soilless potting medium at six wholesale nursery locations across the Willamette Valley, Oregon.
Studies were conducted to determine the efficacy of three species of entomopathogenic nematodes (Heterorhabditis marelatus, Heterorhabditis bacteriophora, and Steinernema riobrave) applied in infected host cadavers or as aqueous applications for black vine weevil larval control.
Using green ash (Fraxinus pennsylvanica) trees as a model for fast-growing shade trees, the objective of this study was to determine whether N application rate and fertilizer type differentially influence cold tolerance of green ash.
A report based on a survey conducted in Australia of 171 blueberry growers in four Australian states to collect detailed information on cultural practices that have been shown to effect the infection of commercial plantings with ericoid mycorrhizal fungi (EMF).
This study focuses on early season changes in nitrogen (N) uptake and amino acid distribution at different root zone temperatures to test whether (1) temperature effects on N uptake are influenced by plant growth stage, and (2) changes in amino acid distribution are related to N uptake.
