Post-Transplant Root Production, Mortality, and Periodicity of Landscape-Sized Shade Trees
… knowledge of rooting behavior of transplanted trees is needed to better understand plant establishment. The objectives of this research were to: 1) determine if transplant timing affected root system regeneration of northern red oak (Quercus rubra L.) and willow oak (Q. phellos L.), 2) …

Cocoa yield, nutrients and shade trees in traditional cocoa agroforests in a climate change context: a case study in Bahia, Brazil
… Cocoa, an understorey crop, is planted under the shade of native Atlantic Forest trees and exotic fruit trees introduced by the farmers. These cabrucas have high conservation value but very low cocoa yield. In my thesis I investigate the factors limiting cocoa yield and how to increase yield in …

Root Regeneration of Transplanted Trees in Relation to the Status of Carbohydrate Levels and Root Invading Fungi
The natural root distributions of 7 species of shade trees (Norway, red and sugar maple, green ash, redbud, ginkgo and pin oak), growing under nursery conditions were characterized. In general, the vertical distribution of the major roots showed the greatest development at the soil depth of 13-38 …
