Phenolic Composistion of Basil Plants is Differentially Altered by Plant Nutrient Status and Inoculation with Mycorrhizal Fungi

Management
Four cultivars of basil were inoculated or not with the arbuscular mycorrhizal fungus (AMF), Rhizophagus (formerly Glomus) intraradices (Schenck & Smith) Walker & Schubler and grown with a fertilizer to access whether 1) P availability and inoculation with AMF influences the phenolic composition of basil; and 2) treatment effects on phenolic composition are related to plant nutrient status.

Modification of Root IAA Concentrations, Tree Growth, and Survival by Application of Plant Growth Regulating Substances to Container-grown Conifers

Nursery Crops
Field trials were conducted to assess the potential to modify the IAA concentration in roots, root growth responses, and plant survival by root application of plant growth regulators (PGRs) such as IBA, NAA, and ethylene, or alginate, a moisture retention material.

Influence of Ectomycorrhizal Fungal Inoculation on Growth and Root IAA Concentrations of Transplanted Conifers

Nursery Crops
USDA-ARS affiliated researchers tested the hypothesis that: (1) IAA concentration of mycorrhizal conifer roots is influenced by the in vitro (IAA and ethylene) production capacity of their associated ectomycorrhizal fungi; and (2) increased concentrations of root IAA cause an increase in root growth resulting in improved seedling growth and survival.

Root Culturing in Bareroot Nurseries

Nursery Crops
Information provided on the bareroot nursery practice of root culturing. Root culturing is defined by the author as a general term for nursery cultural practices designed to modify root growth or morphology while the seedling is still in the nursery bed.

Susceptibility of Pacific Northwest Conifers to Phytophthora Root Rot

Plant Disease
A study was conducted on Phytophthora root rot and the susceptibility of Pacific Northwest conifers. Twelve species of conifer were tested for susceptibility to five species of Phytophthora. Report includes methods, results, conclusions, and recommendations.

Strategies for Turfgrass Renovation

Management
Practical strategies for the renovation of turfgrass, used to improve existing turf or change grass species for improved performance. The basic strategies discussed include simple overseeding, overseeding following suppression of existing turf, and complete renovation.

What Went Wrong? Problems With Athletic Fields

management
A thorough discussion involving athletic fields and associated problems. The Oregon State University affiliated author addresses the common problem of field use and drainage in an athletic field. Possible causes of drainage problems, explanations, and solutions are provided.

Plant Disease
A technical report on what is know and what is not known about Pseudomonas syringae in the nursery industry. Main topics are plant symptoms, severity of the disease, classification of Pseudomonas syringae isolates, sources and survival, hosts, and controls and recommendations.

Controlling Moss in Lawns

Weeds
Mossy lawns are common in the Pacific Northwest. Two mosses typically found invading Western Oregon lawns are Rhytidiadelphus sp. and Brachythecium albicans. Cultural, mechanical, and chemical control methods are offered as a guide to help control moss in lawns.

Searching for Perfect Turf

Management
Informative look at lawn grass selection, popular grass species, and management practices. Specific grass species discussed includes tall fescue, fine fescue, Kentucky bluegrass, perennial ryegrass, bentgrass, highland bentgrass, colonial bentgrass, Poa trivialis, Poa annua, and Holcus lanatus.
