| (g. plant− 1) | (g. plant− 1) | (g. plant− 1) | ||
| C291 | 5 mM | 25.18 ± 1.00 b | 1.37 ± 0.09 ab | 26.55 ± 1.09 b |
| 0.5 mM | 20.29 ± 1.05 c | 1.17 ± 0.21 ab | 21.46 ± 1.13 c | |
| C716 | 5 mM | 28.76 ± 1.44 a | 1.45 ± 0.06 a | 30.21 ± 1.50 a |
| 0.5 mM | 17.27 ± 1.62 d | 1.12 ± 0.10 b | 18.39 ± 1.61 d | |
| FA | 0.14 | 0.04 | 0.14 | |
| FN | 114.39** | 10.60* | 107.87** | |
| FA*N | 18.60** | 0.64 | 17.12** |
FA, FN, and FA*N refer to the F values of the accession, N treatment, and the interaction between the accession and N treatment, respectively. ** indicates significance at the level of P < 0.01; the letters after the number represent significant differences (P < 0.05).
