Effect of CaCl2 (0.5%) and SNP (100 μM) as seed and foliar treatment on seed germination, shoot length, root length, seedling vigor index, total chlorophyll content, trichome density and yield in tomato plants
| Sets | % Seed germination | Shoot length (cm) | Root length (cm) | Seedling vigor index | Total Chlorophyll [mg of total chlorophyll g fresh tissue−1] | Mean trichome density (no./microscopic field) | Yield (g/pot) |
|---|---|---|---|---|---|---|---|
| Control | 80.33 ± 1.52b | 6.53 ± 0.35c | 5.2 ± 0.5c | 941.93 ± 46.41c | 0.70 ± 0.08b | 9.66 ± 1.52c | 115.66 ± 4.04b |
| Cacl2 | 88.66 ± 1.15a | 9.56 ± 0.85a | 7.1 ± 0.26a | 1478.4 ± 110.26a | 1.11 ± 0.15a | 17 ± 1.73a | 175 ± 7.21a |
| SNP | 87 ± 1a | 8.33 ± 0.51b | 6.16 ± 0.35b | 1261.7 ± 43.15b | 0.73 ± 0.08b | 13.66 ± 1.52b | 167 ± 6.24a |
Values represent mean ± SE of three separate experiments, each in triplicate
CaCl 2 Calcium chloride, SNP sodium nitroprusside
Different letters within the row indicate significant difference (p < 0.05) from the control set using Duncan’s multiple range test. Same letter within the row denotes no significant difference between the groups
