Main effects of genotypes and the NH4:NO3 ratio on the number and length of true leaves, yield and height of microgreens (second experiment).
| True Leaves | Leaves Length | Yield | Seedling Height | |
|---|---|---|---|---|
| Number Seedling−1 | cm | g cm−2 | cm | |
| Genotype (G) | ||||
| Broccoli raab | 2.00 ± 0.10 a | 1.39 ± 0.10 a | 0.21 ± 0.02 b | 9.09 ± 0.27 b |
| Broccoli | 1.00 ± 0.10 b | 0.40 ± 0.01 b | 0.22 ± 0.03 b | 9.84 ± 0.19 a |
| Cauliflower | 1.00 ± 0.10 b | 0.40 ± 0.01 b | 0.29 ± 0.03 a | 9.78 ± 0.48 a |
| NH4:NO3(%) (R) | ||||
| 5–95 | 1.33 ± 0.05 | 0.71 ± 0.46 | 0.23 ± 0.04 | 9.46 ± 0.65 |

Significance: ***, and * respectively for p ≤ 0.001 and p ≤ 0.05; NS, not significant. Means values (± standard deviation) within each column and main effect followed by different letters are significantly different, according to SNK test (p = 0.05).
