Analysis of Arabidopsis Light-Sensitive Mutants Grown Under Different Ratios of LED or Fluorescent Lighting

Analysis of Arabidopsis Light-Sensitive Mutants Grown Under Different Ratios of LED or Fluorescent Lighting

Our analysis of leaf size, shape, and number, as well as days to flowering, indicated differences in growth patterns between light conditions. Mid PPFD and max PPFD LEDs also showed some phenotypic growth differences compared to fluorescent lighting.

However, the LED lighting did not cause the same temperature increase as fluorescent lights (~5 degrees Celsius cooler); many of the major growth differences might therefore be due to differences in temperature, rather than light. Overall, our findings suggest no reason to delay a transition to LEDs, even for studies involving light signaling.
