Investigating Ph Banding Kinetics Of Chara Corallina In Alternating Light Conditions With Rectangular Pulse Voltammetry, Matthew C. Zandee Apr 2016

Investigating Ph Banding Kinetics Of Chara Corallina In Alternating Light Conditions With Rectangular Pulse Voltammetry, Matthew C. Zandee

Masters Theses

Chara corallina is an important biological model due to its large internodal cells, the simple shape, and the wide range of techniques that can be used to study it. The alternating acidic and basic banding pattern of Chara corallina upon illumination has been studied and well described over the past several decades. However, much of this complex mechanism is not fully understood. Few studies have shown how the acidic and basic regions have responded in real time as lighting conditions change. Utilizing rectangular pulse voltammetry (RPV) and pH-sensitive carbon microelectrodes along the cell wall allows for a real time profile …


Applicability Of Pigment Compounds For Reducing Light Stress In Bentgrass, Gregory Keith Bartley Aug 2012

Applicability Of Pigment Compounds For Reducing Light Stress In Bentgrass, Gregory Keith Bartley

Masters Theses

Chlorinated copper phthalocyanine (Signature) and pulverized cells of Chlorella vulgaris (Chlorella) were evaluated in a controlled environment for their ability to act as photoprotectants under supraoptimal levels of ultraviolet (UV) and photosynthetically active radiation (PAR) when applied to plant leaves. Plant pigment changes were documented using High Performance Liquid Chromatography following 1 week of exposure to supraoptimal light in two separate experiments incorporating UV (106.6 μmol m-2 s-1) and PAR (760.6 μmol m-2 s-1) over a 12h photoperiod. Supraoptimal levels of UV and PAR light were found to cause significant reductions in Agrostis palustris chlorophyll and carotenoid leaf pigment levels. …
