ResumoThe physiological effect of new FA antitranspirant on winter wheat was studied in field trials. The new FA antitranspirant was sprayed at ear filling stage at the concentrations of 0.5, 1.0, 1.5 and 2.0 ml·L-1. The results indicated that new FA antitranspirant increased nitrate reductase activity (NRA), free proline content, chlorophyll content and water content of leaf, thus drought stress can be mitigated. The new FA antitranspirant increased photosynthesis, reduced stomatal opening status and transpiration rate, thus led to growth stimulation and water loss reduction. New FA antitranspirant resulted in an increase of grain yield by 7.2% at the optimal concentration of 1.5 ml·L-1.
