Response of Rice Nitrogen Physiology to High Nighttime Temperature during Vegetative Stage

Figure 3

Leaf soluble proteins content (a), soluble sugar content (b), and free amino acid content (c) of rice seedling. Plants were grown under two temperatures of 22°C (CK) and 27°C (HNT) with three nitrogen levels of 10 mg N/L (LN), 40 mg N/L (MN), and 160 mg N/L (HN). Range bars indicate the standard deviation (𝑛=3). ANOVA results are embedded in the figure: ns: not significant; *𝑃<0.05; **𝑃<0.01. Columns with the same letter are not significantly different at 𝑃<0.05 by Tukey’s HSD.
