Growth Parameters Of 'Golden Delicious' Apple Trees (Malus X Domestica Borkh), Biying Shi Apr 2015

Growth Parameters Of 'Golden Delicious' Apple Trees (Malus X Domestica Borkh), Biying Shi

Open Access Theses

High yield and high quality of tree fruit result from appropriate orchard design and management practices. This requires an accurate knowledge of vegetative growth, branching, and flowering processes of fruit trees. Tree development knowledge is the fundamental information necessary to build functional-structural tree models, which have various applications in agriculture. To build such models, information is needed on the distributions of growth parameters, not merely means as are often reported. The objective of this study was to quantitatively analyze shoot development and examine the correlations between fruit quality and light distribution in apple trees. This study was conducted in 2014, …


Application And Implications Of Rule-Based Pruning Of Apple Trees, Jacob B. Franzen Apr 2015

Application And Implications Of Rule-Based Pruning Of Apple Trees, Jacob B. Franzen

Open Access Theses

Labor is one of the largest operating costs associated with tree fruit production in the United States. Pruning and harvest can easily eclipse over a quarter of an orchard's operating budget. Additionally, labor sources are becoming increasingly difficult to find while worker pay keeps going up. As a result, it appears that labor costs will continue to rise for the foreseeable future. Work on developing mechanized alternatives to pruning is seen as one of the key areas to reduce an orchard's dependence on human labor. The objective of this study was to test a set of simplified pruning rules (RUL), …
