SL = shoot length; SDW = shoot dry weight; RDW = root dry weight; TRL = total root length; AD = average diameter; RDW/SDW = root dry weight per shoot dry weight; TPB = total plant biomass; RV = root volume; SA = surface area; BN = branching number, * significant at P < 0.05 and ** significant at P < 0.01.
