Effect of application of iron (Fe) and ?-ketoglutaric acid on growth, photosynthesis, and Fe content in fragrant rice seedlings

At a three-leaf stage, two Fe treatments [0 mg kg-1 (Fe-) and 20 mg.kg-1 (Fe+) in the form of FeCl3] were used soil pot then concentrations α-ketoglutaric acid L-1 (A-) 50 (A+)] sprayed to rice plants Meixiangzhan Yuxiangyouzhan cultivars. We showed that seedlings exhibited an increased length fresh dry mass shoots roots with Fe+A- Fe-A+, as well content greatly. Both morphological characteristic values promoted photosynthesis. Interestingly, Fe+A+ notably affected photosynthesis fragrant seedlings; however, it exerted no significant differences on other parameters. Overall, had potential for improving growth seedlings. The interaction between regulated seedling leaves, which provided evidence further improvement cultivation.
