Foliar sprays of 1.0% ZnSO4 and 0.5% sorbitol significantly reduce sunburn and improve fruit yield and quality in 'Murcott' tangerine under heat and high irradiance.
- Why it matters: Citrus fruits in arid environments face severe sunburn and yield losses due to high temperatures and solar radiation, highlighting the need for sustainable mitigation strategies.
- What they did: The study applied foliar treatments of potassium silicate, zinc sulfate, and sorbitol three times during the growing season on five-year-old trees, measuring their effects on fruit and biochemical traits over two seasons.
- The result: Treatments with 1.0% ZnSO4 and 0.5% sorbitol increased total fruit yield by up to 20.15% and 14.34%, respectively, while reducing sunburn incidence by over 44%, and were linked to enhanced antioxidant enzyme activities and fruit quality parameters.
