Kin recognition, not competitive interactions, predicts root allocation in young Cakile edentula seedling pairs.

Abstract excerpt

• Recent studies have demonstrated sibling vs stranger differences in group root allocation in plants, suggesting that plants have the potential for kin discrimination in competition. However, morphology differences could potentially be generated by competition-based mechanisms. Here, we tested these hypotheses for the sibling vs stranger differences in root allocation in Cakile edentula. • Seeds were planted in...
