Table 3. The contents and yields of Cu, Fe, Mn and Zn in the three cuts of whole lucerne.
The average ± standard deviation was shown as the results.
| Cut | Cu | Fe | Mn | Zn | |
|---|---|---|---|---|---|
| Content (mg/kg) | 1st | 15.52 ± 4.30a | 600 ± 139b | 30.20 ± 5.22b | 32.19 ± 6.25a |
| 2nd | 13.08 ± 1.14a | 559 ± 184b | 33.60 ± 7.150b | 23.02 ± 3.82b | |
| 3rd | 14.13 ± 6.07a | 1,026 ± 213a | 46.27 ± 5.73a | 37.50 ± 10.46a | |
| Yield (mg/m2) | 1st | 5.65 ± 2.94B | 211 ± 103B | 10.34 ± 3.98B | 11.62 ± 6.08B |
| 2nd | 6.18 ± 2.61AB | 271 ± 164B | 16.02 ± 8.55B | 10.71 ± 4.57B | |
| 3rd | 8.04 ± 3.12A | 637 ± 260A | 29.29 ± 11.81A | 22.95 ± 8.26A |
Note:
The significant difference was determined by one-way ANOVA, it was represented as the different lowercase letters on the contents, and as the different capital letters on the yields (P<0.05).
