Phenotyping Tomato Root Developmental Plasticity in Response to Salinity in Soil Rhizotrons
Relationship between salt tolerance parameters and RSA traits. (a) Na+ content in root salt and branched zone. (b) Ratio K+/Na+ in root salt and branched zone. (c) DW: dry weight of leaves and NLR. DW leaves and RSA traits were represented as the ratio between salt divided by control values. Different symbols represent the five genotypes. Correlation between pairs of variables was tested using the Pearson correlation coefficient squared (2). Statistically significant correlations are shown by an asterisk ,. HR: high resiliency area; LR: low resiliency area.
