Comparison Of Understory Chemical And Mechanical Treatments To Promote Regeneration Of Desirable Forestland Species, Rebecca Rachael Tyler
Comparison Of Understory Chemical And Mechanical Treatments To Promote Regeneration Of Desirable Forestland Species, Rebecca Rachael Tyler
MSU Graduate Theses
Invasive woody plants and trees can have a negative impact on desired tree regeneration in the understory of forest stands, and forage density in grassland sites. An assessment of chemical and mechanical treatments on woody plants in the understory of forestland and in grassland is needed. Two experiments were set up in two forest stands and in two grassland/forest edge sites, with two treatment times during the growing season in the first year of the study. On the forestland sites, chemical and mechanical treatments were applied on undesired woody plants to see if they effect the regeneration of desired tree …
Effects Of Phosphorus Availability On Growth And Leaf Nutrient Concentrations In Wheat, Oat, And Cereal Rye, Jerri Lynn Dodson
Effects Of Phosphorus Availability On Growth And Leaf Nutrient Concentrations In Wheat, Oat, And Cereal Rye, Jerri Lynn Dodson
MSU Graduate Theses
Adequate soil phosphorus (P) is critical for the growth and nutrient content of forages for grazing animals. On low fertility soils, tall fescue responds to P fertilization with increased yields and improved leaf nutrient contents of P, magnesium (Mg), calcium (Ca), and potassium (K) in winter months. My objective was to examine the effect of P availability on growth and leaf nutrients in annual cereal grains commonly grown for winter forage. Soft red winter wheat (Triticum aestivum), oat (Avena sativa), and cereal rye (Secale cereale) were grown hydroponically in greenhouse conditions in complete nutrient solutions with varying P concentrations of …
Genetic Analysis Of Cold Hardiness In A Population Of Norton (Vitis Aestivalis) And Cabernet Sauvignon (Vitis Vinifera) Hybrids, Daniel Bracy Adams
Genetic Analysis Of Cold Hardiness In A Population Of Norton (Vitis Aestivalis) And Cabernet Sauvignon (Vitis Vinifera) Hybrids, Daniel Bracy Adams
MSU Graduate Theses
Vitis aestivalis derived Norton is an American grape species common throughout the Midwest. Norton grapes are known for their disease resistance, high antioxidant content and cold hardiness; however, they typically have a lower wine quality than European varieties like Cabernet Sauvignon. Thus, there is a desire for new grape varieties with both the durability of native grapes and the quality of European grapes. This study focuses on the cold hardiness of Norton and Cabernet Sauvignon hybrids. Buds were collected from each hybrid once per month from December to February during the winters of 2015-2016 and 2016-217. The buds were attached …
