Mean values within lines and cultivars marked with the same letters do not differ significantly according at p ≤ 0.05 to Duncan’s multiple range test. In parenthesis, percentage values in comparison to the control (C) are given. The results of two way ANOVA analysis of variance are presented in the lower part of the table. The sources of variance for grain and mass number and biomass were as follows: two cultivars, four treatments, and interaction between cultivar and treatment.
significant at p ≤ 0.05, 0.01, 0.001, respectively; ns, not significant.
