Deep root penetration, which allows access to deep soil water and hydraulic lift, may help plants to overcome drought stress. The aim of this study was to evaluate the ability of sixteen food crop spe...
Cold- or Heat-Tolerance of Leaves and Roots in Perennial Ryegrass Determined by 1H-NMR
Arrhenius plots Cold stress Dynamic states of water Heat stress NMR relaxation times (T1,T2) Organ Perennial ryegrass Water compartment
2009/7/28
Dynamic states of water in the leaves and roots of perennial ryegrass (Lolium perenne L.) exposed to cold and heat stresses were studied by using 1H-NMR. NMR spin-lattice relaxation times (T1) of leav...
