Physiological Effect of New FA Antitranspirant Application on Winter Wheat at Ear Filling Stage
摘要
The physiological effect of new FA antitranspirant on winter wheat was studied by field trial. The new FA antitranspirant was sprayed at ear filling stage, using the following concentrations: 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, enlarged stomatal conductance and reduced transpiration rate, thus led to growth stimulation and water loss reduction. New FA antitranspirant caused an increase of grain yield by 7.2%, under the optimal concentration 1.5 mL L-1.
