Fig. 1From: Compositional Shifts and Assembly in Rhizosphere-Associated Fungal Microbiota Throughout the Life Cycle of Japonica Rice Under Increased Nitrogen FertilizationSoil enzyme activities related to nitrogen in the four different nitrogen fertilization levels at the tillering and heading stages. Error bars indicate the standard deviation of three replicates. Different lowercase letters indicate a significant difference between the nitrogen fertilization levels at the two growth stages at p < 0.05, n = 3.1 International Unit (IU) = 1 μmol/minBack to article page
