Effects Of Bacillus Mycoides Supplement In A Reduced Frequency Fungicide Program On Chambourcin Grapevines (Vitis Vinifera L.), Ryan Alan Mairs
Effects Of Bacillus Mycoides Supplement In A Reduced Frequency Fungicide Program On Chambourcin Grapevines (Vitis Vinifera L.), Ryan Alan Mairs
Masters Theses & Specialist Projects
Fungal diseases pose significant challenges for grapevine producers in Kentucky due to the region’s abundant moisture and relative humidity. Methods to reduce fungicide application frequency would prove both economically and temporally valuable to producers. A field experiment was established in Bowling Green, KY in 2017 to investigate Bacillus mycoides isolate J (LifeGard) as a supplement to a fungicide program for systemic acquired resistance (SAR). Three fungicide treatment regimens were implemented consisting of a program modelled from the Midwest Fruit Pest Management Guide (2017) and an identical program supplemented with 140 g ha-1 LifeGard per application (both applied on 14 day …
Accessing Chilling Conditions For Perennial Fruit Crop Production In Kentucky, Yao Xue
Accessing Chilling Conditions For Perennial Fruit Crop Production In Kentucky, Yao Xue
Masters Theses & Specialist Projects
Temperate Region fruit and nut trees, and many other perennial plants, require cool winter temperatures (chilling hours) to ensure leaf and flower bud production in the following season. Temperate Regions are characterized by variable winter and spring temperatures. Failure of meeting sufficient chilling requirement results in deformed fruits, unequal maturation, and other plant deformities, thereby reducing quality and yields. Chilling requirements are expressed as number of accumulated hours within a range of approximately 32º to 45ºF or 0º to 7.2ºC. These requirements are specific for level of temperature, length of temperature period, and species and cultivar of plants. Information on …
Clarification Of Basal Relationships In Rubus (Rosaceae) And The Origin Of Rubus Chamaemorus, Karen Michael
Clarification Of Basal Relationships In Rubus (Rosaceae) And The Origin Of Rubus Chamaemorus, Karen Michael
Masters Theses & Specialist Projects
Determination of phylogenetic relationships among ancestral species of Rubus has been elusive. Most Rubus species (including blackberries and raspberries), representing nine of the 12 subgenera, occur in a large, well supported clade named 'A' for reference). The remaining nine species are excluded from this group and represent three subgenera: subg. Anoplobatus (R. bartonianus, R. deliciosus, R. neomexicanus, R. odoratus, R. parviflorus, R. trilobus), subg. Chamaemorus (R. chamaemorus), and subg. Dalibarda (R. lasiococcus, R.pedatus). In addition, Rubus dalibarda L. is often treated in its own monotypic genus as Dalibarda repens L. Phylogenetic analyses of DNA sequence data from chloroplast regions and …
