The reaction norms of the non-saline and coastal ecotypes of Ipomoea cairica on biomass allocation according to the saline treatment levels.

NS, non-saline treatment; SA, saline treatment. LMR, leaf mass ratio; RMR, root mass ratio. The P-value reflects the statistical significance of the difference in reaction norm between the two ecotypes, which is represented by the interaction of saline treatment with ecotype (Table 3). Values presented are means ± SE. Means with the same letter were not significantly different (P
