Recent evidence suggests that self/non-self discrimination exists among roots; its mechanisms, however, are still unclear. We compared the growth of Buchloe dactyloides cuttings that were grown in the presence of neighbors that belonged to the same physiological individual, were separated from each other for variable periods, or originated from adjacent or(More)
Plant invasiveness was commonly attributed to the invader’s competitive superiority over the native community, but a general pattern supporting this prediction is still lacking. This is particularly enhanced by the fact that competitive dominance and its role in plant invasiveness require the use of scarcely-practiced experimental elements. Here, we used a(More)
Physiological integration between ramets can ameliorate the growth and survival of clonal plants in spatially-heterogeneous environments, as ramets from favourable patches can provide support to those found in stressful patches. However, the advantage conferred by clonal integration might also depend on the evolutionary history of plants with regards to the(More)
