Table 2. Leaf growth parameters (biomass, in g DW; and leaf expansion area, in cm2) and total Fe concentration on DW (in μg g−1DW) and surface (in μg cm−2) bases measured in the non-chlorotic and chlorotic fully expanded leaves of ‘Navelina’ orange trees.
| Non-chlorotic | Chlorotic | ANOVA | |
|---|---|---|---|
| Leaf growth parameters | |||
| Biomass (g DW) | 0.358 | 0.227 | * |
| Leaf expansion area (cm2) | 21.4 | 15.7 | * |
| Total Fe concentration | |||
| μg g−1 DW | 65.6 | 60.7 | ns |
| μg cm−2 | 1.10 | 0.88 | * |
Notes:
Values are the mean of six biological replicates (n = 6). For a comparison of mean, a variance analysis (ANOVA), followed by the least significant differences (LSD) test, calculated at the 95% confidence level, was performed. Significant differences are indicated as follows:
p < 0.05; ns, not significant; DW, dry weight.
