Title

Plasticity in relative growth rate after a reduction in nitrogen availability is related to root morphological and physiological responses

Antonio Useche; Bill Shipley Annals of Botany 2010. doi:10.1093/aob/mcq144

Other claims from this paper (9)

Intervention effect Nitrogen decrease reduced specific root area and root length in herbaceous species
Intervention effect Nitrogen decrease reduced areal and length-based unit root rate in herbaceous species
Intervention effect Nitrogen decrease reduced relative growth rate in herbaceous species
Intervention effect Nitrogen decrease reduced bifurcations per root area and per root length in herbaceous species
Association Species with greater plasticity in SRA decrease had smaller reductions in RGR
Association Species with greater reduction in URR(area) and bifurcations had stronger reductions in RGR
Observation Plasticity in URR(area) and bifurcations is not adaptive
Observation Plasticity in SRA is adaptive
Observation Plastic root responses would conserve resources under nutrient stress
