Potential contribution of strigolactones in regulating scion growth and branching in grafted grapevine in response to nitrogen availability.

abstract：:It is generally believed that an osmotically generated pressure gradient drives the phloem mass flow. So far, this widely accepted Münch theory has required remarkably few adaptations, but the debate on alternative and additional hypotheses is still ongoing.
