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 …

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 …
