Effect Of Light Duration On Pulvinar Motor Organ Movements In Phaseolus Vulgaris, Thomas William Rinehart Jan 2004

Effect Of Light Duration On Pulvinar Motor Organ Movements In Phaseolus Vulgaris, Thomas William Rinehart

Presidential Scholars Theses (1990 – 2006)

With a well established model in place, the main objective of this study will be to determine if the pulvinar motor organs have a threshold radiation level to elicit paraheliotropic movements. Plants will be illuminated with full spectrum light at varying intensities and periods. Observation will take place minute-by-minute in an effort to denote certain lighting conditions which might trigger paraheliotropism.
