Internode elongation and strobili production of Humulus lupulus cultivars in response to local strain sensing

Abstract Three different cultivars of Humulus lupulus L. were subjected to a regime of internode touch and bending under greenhouse conditions. Experiments were performed to assess intraspecific variability in plant mechanosensing, flower quality, and yield to quantify the thigmomorphogenic impact o...
