A study of chrysanthemum investigated plants' circadian responses to interruptions in light cycles. Plants were exposed to irregular supplemental light breaks during the night; results showed a correlation between circadian-regulated processes and plant growth. Leaves and stems grew faster in plants grown in short days with irregular light breaks during the night compared with plants grown in a climate with a consecutive long light period. The findings could contribute to energy savings in production greenhouses.
