How much water citrus trees receive during fruit development can have a major impact on fruit size and internal quality, according to new research published in the journal Horticulturae. The study shows that while moderate water stress may improve some aspects of fruit quality, severe drought significantly reduces fruit size and can make fruit much more acidic. Researchers in China …
New research in China suggests that combining traditional color cameras with near-infrared imaging could make automated citrus grading systems much better at detecting surface defects. The technology has the potential to improve packhouse efficiency, reduce the number of defective fruit reaching consumers and help growers maximize the value of their crop. The study, published in the journal Agriculture, was conducted …
Citrus peel has long been viewed as a byproduct of juice processing, often ending up as animal feed or compost. New research suggests it may deserve much more attention.
