Effect Of Hydroculture Methods On Tomato Root Morphology And Anatomy, Lia Maclellan
Effect Of Hydroculture Methods On Tomato Root Morphology And Anatomy, Lia Maclellan
Honors College
Three methods of hydroculture were compared for their effects on the root anatomy and morphology of tomato (Solanum lycopersicum cv. Defiant). A hydroponic deep water culture method, an ebb-flood system using expanded clay pellets as a solid medium and an aeroponic sub-mist system were compared, with a solid peat/perlite medium for control. The treatments were found to have significant effects on plant root and shoot length, as well as root and shoot biomass. Root morphology was visually distinct among treatments, and all methods of hydroculture were associated with a significant increase in vascular tissue in plant roots compared with the …

Interglacial Expansion Of Alpine Glaciers In Garwood Valley, Antarctica, Laura Mattas
Honors College
It is important to understand the response of the Antarctic Ice Sheet (AIS) to ongoing global atmospheric and oceanic warming to anticipate future sea-level change. There are several contrasting views in this regard. Harig and Simons (2015) concur with the IPCC (2013) conclusion that, in recent decades, outflow across the peripheral grounding lines of the ice sheet has exceeded increased accumulation on the interior surface of the ice sheet. In contrast, Zwally et al. (2015) suggest that recent surface accumulation in the interior East and West Antarctica has outpaced peripheral losses. They further suggest that this recent positive imbalance adds …
Heard It Through The Grapevine... Winery Owners Explain The Role Of Sustainability In Maine's Emerging Industry, Michaela Murray
Heard It Through The Grapevine... Winery Owners Explain The Role Of Sustainability In Maine's Emerging Industry, Michaela Murray
Honors College
With increased awareness of humanity’s profound impact on the climate, interest in the notion of sustainability has expanded across all disciplines. The inherent link between food and climate has specifically motivated consideration of sustainability within agricultural and food production sectors. The global wine industry has long acknowledged the social, environmental, and economic sustainability concerns (e.g. triple-bottom-line) of their industry. Beginning in 1992 with The Lodi Winegrape Commission in California, several wine regions including France, Australia and South Africa have developed workbooks and policies for sustainable wine production. The budding wine industry in the state of Maine has yet to explore …
The Effect Of Embryonic Arsenic Exposure On The Sensorimotor Behavior Of Zebrafish (Danio Rerio), Laura Paye
The Effect Of Embryonic Arsenic Exposure On The Sensorimotor Behavior Of Zebrafish (Danio Rerio), Laura Paye
Honors College
The goal of this study is to determine the effect of arsenic exposure on vision in zebrafish (Danio rerio). The optic system of D. rerio is ideal for examining visual defects. Their eyes are similar to eyes of humans and can therefore be useful models in studies of human eye disease. Their optic system functions similarly to humans, so it is beneficial to observe how zebrafish are affected by contaminants in the environment. Arsenic is ubiquitous in groundwater, due to its natural presence in bed rock, but is elevated by human activities. In order to see any …
