Changes in the percentages of tomato genotypes' morphological traits in response to cadmium stress with and without oak leaf biomass pretreated with sodium hydroxide compared to control conditions.

Trait	CdC	CdOBC
Root length (%)	−15.01 ± 2.21 a	−16.33 ± 1.61 a
Shoot length (%)	−18.00 ± 3.03 a	−12.05 ± 3.46 b
Root fresh weight (%)	−25.32 ± 1.57 a	−9.65 ± 1.67 b
Shoot fresh weight (%)	−9.47 ± 1.87 a	−5.12 ± 1.52 b
Root dry weight (%)	−25.12 ± 2.94 a	−5.27 ± 3.01 b
Shoot dry weight (%)	−8.88 ± 0.79 a	−4.48 ± 0.62 b
Total fruit weight per plant (%)	−13.85 ± 1.72 a	−10.43 ± 1.38 b

The negative values represented decreasing percentages of the investigated parameters in comparison to the control conditions. According to Duncan’s new multiple range test, different letters denote statistically significant differences (p ≤ 0.01). The values are presented by the trait index (%) ± standard error. The values represent the average of eight separate evaluations.
