Table 3. Variance analyses for the model, the effects of each experimental factors and their interaction effects on germination percentage, gemination index, seed vigor index, root, and shoot length.

Columns GS, X₁,X₂ and X₃ represent grass species, bacteria concentration, seed priming and priming duration, respectively.
