Seasonal Variation in Growth, Nitrogen Uptake and Allocation by Container-grown Evergreen and Deciduous Rhododendron Cultivars

Nursery Crops

The intent of the study was to expand current knowledge of nitrogen (N) uptake and allocation by container-grown Rhododendron by characterizing the plant growth, the extent of N uptake, and the changes in N storage that occur during the autumn and winter.

Rate of Nitrogen Application During the Growing Season Alters the Response of Container-Grown Rhododendron and Azalea to Foliar Application of Urea in the Autumn

Nursery Crops
Using deciduous and evergreen cultivars of container-grown Rhododendron, the objectives of this study were to determine: (i) whether N application rate during the growing season influenced plant response to foliar urea application in the Autumn; and (ii) whether plant N status in the Winter influenced plant reliance on fertilizer for growth the following Spring.

Differences in Growth, and Nitrogen Uptake and Storage Between Two Container-Grown Cultivars of Rhododendron

The information provided by this study will aid in the development of fertilizer management strategies for container nursery production practices that will decrease fertilizer use and production costs, improve plant quality, while minimizing N losses to the environment.

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).

Timing of Urea Application Affects Leaf and Root N Uptake in Young Fuji/M.9 Apple Trees

The ambitions of the study were to compare the effects of different timings of nitrogen (N) application on leaf and root N uptake, and to determine the distribution of N absorbed by leaves and roots at different times in young Fuji/M.9 apple trees.

Inoculation with Ericoid Mycorrhizal Fungi Alters Fertilizer Use of Highbush Blueberry Cultivars

This study investigates the potential role EMF plays in container-grown blueberry production. Specifically, it was determined whether growth and nutrition of highbush blueberry is influenced by inoculation with various EMF isolates, and whether the response to EMF is altered by the type of fertilizer used.

Isolate-specific Rooting Responses of Leucothoe fontanesiana Cuttings to Inoculation with Ericoid Mycorrhizal Fungi

Nursery Crops
The intent of the study was to determine whether an EMF inoculum, added to the rooting substrate during cutting propagation, can alter root production by L. fontanesiana, and whether responses to inoculation depend on the EMF isolate used as inoculum.

Inoculation with Vesicular-Arbuscular Mycorrhizal Fungi and Rhizobacteria Alters Nutrient Allocation and Flowering of Harlequin Flower

The objectives of the study were to 1) determine whether addition of AMF inoculum into the growing medium of harlequin flower alters aspects of flower production, bulb production, and bulb quality, and 2) assess whether other rhizosphere organisms present in the AMF inoculum play a role in plant response to inoculation.

Spring Growth of Almond Nursery Trees Depends Upon Nitrogen From Both Plant Reserves and Spring Fertilizer Application

Nursery Crops
The purpose of this study was to determine which source of nitrogen (N) (i.e. reserves or spring fertilizer applications) has the greater effect on new growth of almond nursery trees. 'Nonpareil' almond (Prunus dulcis (Mill) D. A. Webb) trees on 'Nemaguard' rootstocks were used in the study.
