Spraying Leaves of Pear Nursery Trees with Urea and Copper Ethylenediaminetetraacetic Acid Alters Tree Nitrogen Concentration Without Influencing Tree Susceptibility to Phytophthora syringae

The specific objectives of the study were to determine whether susceptibility of field-grown pear trees to P. syringae is related to N concentration in stems and is altered by spraying trees with urea or the defoliant CuEDTA at different times in the autumn before and after inoculation with the pathogen.

A Survey of Vaccinium Cultural Practices in Australia Emphasizing Implications for Mycorrhizal Infection

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).

Nitrogen Foliar Feeding has Advantages

An examination of the advantages and affects of nitrogen (N) foliar feeding on the quality of nursery plants. Topics include which N formulation is best, fall applications, advantages of fall foliar nitrogen, and spring applications.

Nutrient Uptake and Distribution in a Mature 'Pinot noir' Vineyard

Report on a study undertaken to investigate nutrient uptake and distribution of mature Vitis vinifera L. 'Pinot noir' vines (23 to 24 years old) grown without irrigation in a region with low summer rainfall common to western Oregon vineyards.

Put Mycorrhizae to use

A discussion about mycorrhizae, a natural fungi that can greatly improve plants' nutrient and water uptake. The authors specifically discuss why mycorrhizae are important, whether or not they are needed, necessary materials, and when and how to use mycorrhizae.

Phosphorus Supply Alters Tuber Composition, Flower Production, and Mycorrhizal Responsiveness of Container-Grown Hybrid Zandtedeschia

The purpose of this study was to determine if arbuscular mycorrhizal fungi (AMF) inoculation influences plant development, reproduction (vegetative and floral), and/ or tuber quality in calla lily (Zantedeschia spp. and hybrids).

Frequency and Intensity of Root Colonization by Ericoid Mycorrhizal Fungi in Nursery Production of Blueberry Plants

Nursery Crops
A report on a survey conducted on commercial nursery plants produced from tissue culture and cuttings to determine when or if ericoid mycorrhizal fungi (EMF) colonize blueberry plants under nursery cultural methods.

Inoculation with Ericoid Mycorrhizal Fungi Alter Root Colonization and Growth in Nursery Production of Blueberry Plants from Tissue Culture and Cuttings

The objectives of this work were to determine whether inoculation of blueberry nursery plant with EMF influences rooting, subsequent plant growth, or mycorrhizal colonization of blueberry plants produced from tissue culture and cuttings.

Cultural Variation and Mycorrhizal Status of Blueberry Plants in NW Oregon Commercial Production Fields

Nursery Crops
The design of the study conducted was to assess the mycorrhizal status of blueberry plants in commercial farms in the Willamette Valley of Oregon and to determine whether relationships exist between cultural practices, root distribution, soil characteristics and level of colonization by mycorrhizal fungi.

Root Damage Affects Nitrogen Uptake and Growth of Young Fuji/M.26 Apple Trees

Nursery Crops
Research was conducted with the intent of evaluating the effect of different levels of root damage at planting on nitrogen uptake and growth of bench-grafted young apple (Malus domestica Borkh 'Fuji'/M.26) nursery trees.
