Photosynthesis Improvements Can Occur In Plants Grown With Little to No Transmittance of UV

University of Thessaly’s Department of Agriculture Crop Production and Rural Environment found UV blocking has either a strongly positive or strongly negative impact on growth of various crops. The writers suggest, before drawing conclusion,


Strongly positive was indicated by increases in plant height, leaf spans and improved yields when compared with plants without any UV blocking. Strongly negative impact was reported when reverse occurred. If the impact was positive or negative with respect to plant height, width or yield, results correlated with plant species and location in the world (proximity to the equator)

About 50% of plants in the study had a positive response to UV blocking . Almost all plants had declines in natural color and nutritive values.
