Assessment Of Three Grape Varieties' Resistance To Five Viruses And Assembly Of A Novel Grapevine Vein Clearing Virus Genome, Michael Ryan Kovens
Assessment Of Three Grape Varieties' Resistance To Five Viruses And Assembly Of A Novel Grapevine Vein Clearing Virus Genome, Michael Ryan Kovens
MSU Graduate Theses
Over 65 viruses are known to infect grapevines, more than any other agricultural crop. Growth, yield, and quality of virus-infected vines suffer, reducing the profitability to grape growers. Therefore, it is critical to identify grape cultivars resistant to these viruses which can be utilized to protect more susceptible varieties from infection. Wine grape cultivar Norton (Vitis aestivalis) and Chambourcin (V. vinifera hybrid), and rootstock St. George (V. rupestris) have been known to be disease tolerant. In the first study, Norton and Chambourcin were infected with Grapevine fleck virus (GFkV), Grapevine leafroll-associated virus 3 (GLRaV-3), Grapevine virus A (GVA), and Grapevine …
The Effects Of Phosphorus And Nitrogen Fertilization On Tall Fescue Nutrient Content, Yield And Baleage Quality, Cheyenne Adele Arthur
The Effects Of Phosphorus And Nitrogen Fertilization On Tall Fescue Nutrient Content, Yield And Baleage Quality, Cheyenne Adele Arthur
MSU Graduate Theses
Tall fescue (Festuca arundinacea Schreb.) is a cool season perennial grass commonly used in year-round forage production systems. Producers often wrap large round bales of tall fescue in plastic. The fermented product of this practice, termed baleage, allows the forage to be stored for later feeding. During periods of rapid growth in the spring and the fall, the nutrient content of tall fescue can be imbalanced and cause nutritional disorders in grazing animals. To improve the nutrition of tall fescue, it is known that fertilization of phosphorus (P) can help improve leaf nutrient content of P, magnesium (Mg), and calcium …
