Main effects of genotypes and nutrient solution strength on number and length of true leaves, yield and seedling height of microgreens (first experiment).
| True Leaves | Leaves Length | Yield | Seedling Height | |
|---|---|---|---|---|
| Number Seedling−1 | cm | g cm−2 | cm | |
| Genotype (G) | ||||
| Broccoli raab | 2.00 ± 0.30 a | 1.43 ± 0.24 | 0.20 ± 0.02 b | 8.60 ± 1.60 ab |
| Broccoli | 1.00 ± 0.10 b | 1.17 ± 0.32 | 0.20 ± 0.05 b | 9.70 ± 1.10 ab |
| Cauliflower | 1.00 ± 0.10 b | 1.23 ± 0.19 | 0.24 ± 0.02 a | 9.10 ± 1.40 b |
| Nutrient solution strength (NSS) | ||||
| 1/2 | 1.03 ± 0.50 | 1.37 ± 0.40 | 0.23 ± 0.01 a | 10.30 ± 0.90 a |
| 1/4 | 1.03 ± 0.50 | 1.33 ± 0.14 | 0.22 ± 0.03 a | 9.30 ± 1.00 b |
| 1/8 | 1.03 ± 0.50 | 1.13 ± 0.15 | 0.19 ± 0.04 b | 7.70 ± 0.80 c |
| Significance | ||||
| G | *** | NS | ** | * |

| G * NSS | NS | NS | ** | NS |
Significance: ***, **, and * respectively for p ≤ 0.001, p ≤ 0.01, 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).
