Table 5. The contents and yields of Cu, Fe, Mn and Zn in the three organs of lucerne.
The average ± standard deviation was shown as the result.
| Organ | Cu | Fe | Mn | Zn | |
|---|---|---|---|---|---|
| Content (mg/kg) | Root | 13.65 ± 4.56a | 962 ± 390a | 32.99 ± 10.12b | 25.88 ± 10.90b |
| Stem | 14.73 ± 4.79a | 578 ± 299b | 27.94 ± 12.03b | 32.38 ± 13.49c | |
| Leaf | 15.28 ± 4.28a | 605 ± 518b | 65.89 ± 19.45a | 39.88 ± 10.75a | |
| Yield (mg/m2) | Root | 2.95 ± 1.72A | 234 ± 190A | 8.34 ± 7.16A | 6.46 ± 5.77A |
| Stem | 2.28 ± 1.01B | 93 ± 70B | 4.49 ± 2.96B | 5.04 ± 2.81AB | |
| Leaf | 1.46 ± 1.09C | 57 ± 61B | 6.31 ± 4.68AB | 3.84 ± 2.99B | |
Note:
The significant difference was determined by one-way ANOVA, and it was represented as the different lowercase letters on the contents, and as the different capital letters on the yields (P < 0.05).
