Fig. 6From: Partial and full root-zone drought stresses account for differentiate root-sourced signal and yield formation in primitive wheatThe allometric relationship between leaf biomass and aboveground biomass in two primitive wheat species diploid (a) and tetraploid (b) under well-watered (CK) and drought stress (nHRS) treatments. The symbols represent the two water treatments (open rectangular panel, well-watered (CK); closed rectangular panel, drought stress (nHRS)). The data harvested came from maturity stage. The fitted linear regressions are given: *P < 0.05; **P < 0.01; ***P < 0.001. Trial 2Back to article page
