Table 2.
Seedling root length, root, and shoot dry weight, and ATP concentration in shoots of Diplotaxis tenuifolia. Data are expressed as mean ± standard deviation (n = 4). Different letters indicate statistically significant difference between treatments at Tukey’s post-hoc test (p ≤ 0.05).
| Treatments | Root Length | Roots DW | Shoot ATP | Shoot DW |
|---|---|---|---|---|
| (mm plant−1) | (mg plant−1) | (nmol g−1 DW) | (mg plant−1) | |
| Ctrl | 65.0 ± 8.83 | 5.08 ± 1.75 B * | 0.094 ± 0.026 | 21.0 ± 0.75 b |
| HS | 49.3 ± 10.4 | 3.88 ± 1.72 B | 0.115 ± 0.031 | 24.7 ± 2.33 ab |
| CaP | 56.7 ± 7.39 | 7.63 ± 2.46 A | 0.093 ± 0.023 | 25.0 ± 3.83 a |
| CaP–HS | 56.4 ± 2.33 | 6.28 ± 2.56 A | 0.123 ± 0.031 | 21.3 ± 2.27 ab |
* Capital letters beside the figures mean that the effect of the CaP treatment is significant for the variable in question according to the Tukey’s post-hoc test, while small letters mean that the interaction CaP × HS is significant.
