Objective To clarify the correlations of drought-induced non-hydraulic root signals (nHRS) with plant growth and grain yield formation could provide a mechanism basis for water-saving agriculture. Method Pot experiments were conducted with two soybean cultivars, i.e, Jinda 74 and Jin 24. nHRS were traced during manipulative progressive soil drying period at branching, early flowering and grain-filling stages. The effect of water deficit on plant biomass and grain yields of the cultivars were investigated un...
