«The biofeedback system successfully maintained a wide range of ETR values in different species, while it also is capable of distinguishing between conversion of light into heat and damage to the photosynthetic machinery as causes for decreases in
light use efficiency,» the authors said.
As the target ETR was decreased during the last 7 hours, conversion of light into heat decreased greatly in lettuce and pothos, with only a small increase in
light use efficiency.
«This suggests that
the light use efficiency of lettuce and pothos was limited by a process other than conversion into heat, likely light - induced damage to the photosynthetic machinery in the leaves,» the authors noted.
In addition, conversion of light energy into heat (a common way for plants to deal with excess light) was upregulated, while
