Table 1. Effects of N supplies on leaf mass per area (LMA), mass-based and area-based leaf N contents (Nmass and Narea), and chlorophyll content.
Treatments | LMA (g m−2) | Nmass (%) | Narea (g m−2) | Chlorophyll content (mg g−1) |
---|---|---|---|---|
High N | 41.9 ± 1.8 b | 3.50 ± 0.02 a | 1.47 ± 0.07 a | 1.01 ± 0.21 a |
Low N | 45.2 ± 0.9 a | 2.28 ± 0.02 b | 1.03 ± 0.02 b | 0.47 ± 0.04 b |
Note: Data are presented as means ± SD with three replications, and each replication contains at least three newly expanded leaves; data followed by different letters are significant at the P < 0.05 level.
