Quercetin application for abiotic stress protection

Tech ID: 19.661

Key Features

  • Spray-on application of quercetin improves water use efficiency in crops
  • Protecting yield in crop plants
  • Demonstrated in wheat, rice, tomato and other species


Professors Guangmin Xia at Shandong University and Xiangdong Fu at the Institute of Genetics and Developmental Biology and their co-workers have demonstrated that application of quercetin to plants reduces the plant’s water requirement without any detrimental effects on carbon fixation, nitrogen assimilation and plant growth. Quercetin applications promote stomatal closing while boosting photosynthetic activity, thus negating the effects of reduced stomatal conductance on carbon fixation.
