Table II. Predictors for growth-related traits.

Selected predictors (ionomic content in the rosette [_rs] or in the root [_rt], biochemical and developmental traits) for the growth-related traits (rosette weight, RGR, root weight, and root length) and the percentage of trait variance each predictor explains on its own and altogether (total). The prediction was done for each growth-related trait in the C, K−, and P− conditions and for the response of the trait to potassium (Kresp) and phosphate (Presp) reduction.
