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 …
An Assessment Of Seven New Grape Varieties And A Study Of Grapevine Vein Clearing Virus In Native Vitaceae Plants, Kaylie A. Austin
An Assessment Of Seven New Grape Varieties And A Study Of Grapevine Vein Clearing Virus In Native Vitaceae Plants, Kaylie A. Austin
MSU Graduate Theses
One of the most effective methods of reducing pesticide application in vineyards is breeding hybrid varieties for disease resistance. The new varieties must be assessed for disease resistance and viticultural traits. This thesis focuses on seven new varieties from a cross of ‘Norton’ and ‘Cabernet Sauvignon’. ‘Norton’ was chosen because of its disease resistance and cold hardiness. ‘Cabernet Sauvignon’ was selected because of its high-quality wine making berries. The cross was made in 2005, seven were selected in 2011, and evaluation began in 2016. Using Botrytis cinerea as a model pathogen, resistance was measured with an incidence rate and severity …
Comparison Of Serial Pgf2Α Protocols For Control Of The Estrous Cycle In Mares, Kaleigh Marie Potter
Comparison Of Serial Pgf2Α Protocols For Control Of The Estrous Cycle In Mares, Kaleigh Marie Potter
MSU Graduate Theses
Prostaglandin F2α is commonly administered to manipulate the estrous cycle in mares, at a dosage of dinoprost tromethamine (Lutalyse®) at 10 mg, administered IM. My objectives were to compare three serial low-dose PGF2α protocols, and determine the most effective treatment in terms of number of injections, intensity of protocol, time allocated, and labor. Quarter Horse mares (n=11) were used in a crossover design. Lutalyse was administered at 1.1 mL per injection: treatment 1- PGF2α once 6d post-ovulation; treatment 2- PGF2α twice daily 0 d, 1 d, and 2 d, then once 3 d and 4 d post- ovulation; treatment 3- …
