But future improvements to orchard systems likely will be made through fine-tuning techniques instead of radical changes, says Italy’s Dr. Luca Corelli. Previous scientific studies have helped growers understand the importance that light plays in fruit production, said Corelli, plant physiologist in the horticultural department of the University […]
