dc.description.abstract | The circadian rhythm serves to match plant physiology and behavior with the environmental
cycles caused by the rotation of the planet. The circadian rhythm contributes towards the
structure and function of plants and their overall performance which is an important
consideration in agriculture. Arabidopsis has served as a model plant for understanding circadian
function, but it is important to establish if these lessons can be extrapolated to other species. This
study investigated the effect of a non-circadian light cycle on Lactuca sativa (lettuce) plants
reared from germination in those conditions. Canopy size, gas exchange, and carbohydrate
storage and use were investigated, and it was found through repeated measures ANOVA
analyses that non-circadian light cycles are indeed associated with decreases in many metrics
commonly associated with plant performance such as stomatal conductance, carbon dioxide
exchange, leaf-level sugar storage, and canopy area, but not with total canopy volume or total
biomass. This opens up the possibility of further analysis into the feasibility of using non-circadian light cycles in controlled environment agricultural settings and indicates some cross
species agreement with the effects these light cycles are found to have with the model species
