Fibrolytic Enzymes And Silage Inoculants To Improve The Nutritive Value Of Silage, Salvador Ordaz

Graduate College Dissertations and Theses

Ensiling is one of the most common processes used as a conservation method for forages on farms and plays an important role in farm economics. Therefore, with the aim to improve the conservation and the nutritive value of silage, the utilization of silage additives such as fibrolytic enzymes (FE) and lactic acid bacteria (LAB) inoculants has been a common on-farm practice. FE are enzymes capable of breaking down complex polysaccharides such as cellulose and hemicellulose. The latter results in an increased substrate availability for epiphytic and inoculated LAB during silage fermentation, thus promoting a higher production of organic acids such …

Evolution Of Duplicated Han-Like Genes In Petunia X Hybrida., Beck Powers

Graduate College Dissertations and Theses

Gene duplications generate critical components of genetic variation that can be selected upon to affect phenotypic evolution. The angiosperm GATA transcription factor family has undergone both ancient and recent gene duplications, with the HAN-like clade displaying divergent functions in organ boundary establishment and lateral organ growth. To better determine the ancestral function within core eudicots, and to investigate their potential role in floral diversification, I conducted HAN-like gene expression and partial silencing analyses in the asterid species petunia (Petunia x hybrida). My results indicate duplication of HAN-like genes at the base of Solanaceae followed by expression diversification within the flower. …

Choices And Preferences Of Vermont Master Gardeners - Do Socio-Demographics Matter?, Grace Matiru

Graduate College Dissertations and Theses

ABSTRACT

This study was designed to characterize the choices, preferences and motivations of fruit and vegetable gardeners in Vermont, and to determine whether socio-demographic characteristics affect some of these choices, preferences and motivations. Using a survey of Vermont Extension Master Gardeners (EMGs), data were gathered over a 3-year period (2011-2013). The findings show most EMGs (>90%) garden in private home gardens, and the most popular vegetables grown were tomatoes, herbs, and salad greens. Beans, cucumbers and peppers sere also popular and among fruits, blueberries, apples, raspberries and strawberries were grown by over 40% of EMGs. Approximately 10% of EMG …

Master's Project: An Ecological Inventory And Assessment Of The Pond Brook Region In Monkton, Vermont, Lyra D. Brennan

Rubenstein School Masters Project Publications

The Pond Brook Watershed in Monkton, Vermont, is a 19,000-acre patchwork of northern white cedar swamps, oak-covered ridgetops, and prime agricultural soils. Over 95% of the watershed is privately owned, limiting ecologists’ abilities to conduct a landscape-scale field assessment or determine significant natural resources within the area. I was hired by the Agricultural and Natural Areas Committee of Monkton [ANAC] to conduct an ecological assessment of the Pond Brook Watershed by visiting a diverse sampling of privately-owned parcels and inventorying the 300-acre town owned wetland.

I worked with over 30 individual landowners to understand current and historical land use in …
