Methods of Nitrogen Application in Summer Affects Plant Growth and Nitrogen Uptake in Autumn in Young Fuji/M.26 Apple Trees

Soil
The intent of this study was to determine the (1) effect of soil versus foliar nitrogen (N) applications during the summer on tree growth, and (2) effect of soil versus foliar N applications during summer on N uptake in the autumn in young apple trees.

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.

Effects of Spring Soil Nitrogen Application on Nitrogen Remobilization, Uptake, and Partitioning for New Growth in Almond Nursery Plants

Fertilizer
A study was conducted on almond trees to (1) determine whether soil N application alters N remobilization; (2) quantify the effects of soil N availability in the spring on N uptake, distribution, and new growth; and (3) determine the most efficient time for spring soil N applications.

N Uptake, Soil Retention and Loss of Soil-Applied 15NH4 15NO3 in Young Fuji/M.26 Apple Trees with Different N Status

Nursery Crops
The purpose of research conducted on young apple (Malus domestica Borkh) trees was to determine the fate of soil applied nitrogen to young apple trees and the influence of tree nitrogen status on nitrogen uptake by young apple trees.

Physiology and Culture of Picea pungens 'Hoopsi'/Picea abies Grafts

Nursery Crops
A study was conducted to determine the physiology of graft formations in Picea pungens 'Hoopsi' scions grafted on Picea abies rootstocks. The purpose of the study was to identify factors limiting grafting success and improve production techniques.

Lilac...Year-Round Cut Flower? Duel Purpose Plant?

Greenhouse Crops
A guide for the production of lilacs for the duel purposes of cut-flower production and landscape plantings. The history of the lilac as a forced, cut flower is summarized along with descriptions of species and cultivars, growth and development, forcing and flowering, and propagation methods.

Minute Nursery Trees, a Break-Though for the Tropics?

Rootstocks
A method for producing 'mini-trees' for commercial production in the nursery environment. The author discusses how the 'mini-trees' are produced, packing and transport, second-stage nursery and field establishment, the scope for mini-trees in the tropics, and a project proposal.

Grafted Tree Survival Increased, Grafting Season Extended by Inexpensive Hot-Callusing Device

Propagation
Studies were conducted to test the effectiveness of using a hot-callusing device when grafting a variety of different trees. The authors discuss the results of the hot-callusing method and it's effects on apple, peach, pear, prune, and Douglas-fir trees.

Every Christmas Tree a '10'

Christmas tree
The idea of using clones in the Christmas tree industry is debated by the Oregon State University affiliated author. The use of clones could lead to more uniform sellable trees but could also lead to a lack of genetic diversity in the Christmas tree industry.

'Autumn Blaze' - New Callery Pear Introduction from Oregon State University

Breeding and Selection
Callery pear (Pyrus calleryana) cultivars are the subject discussed after the introduction of a new cultivar, 'Autumn Blaze', to the nursery industry. The characteristics of 'Autumn Blaze' are addressed along with information regarding other Pyrus calleryana cultivars.
