X. Pons ; G. Tatchell | 1995The performance of clones of Rhopalosiphum padi and Sitobion avenae from England and Spain was examined on drought-stressed tillering winter wheat in an environment chamber at 14 +/- 1 degrees C. Two different levels of drought stress and an uns[...]article/chapitre/communication
R. Serraj ; B. Shelp ; T. Sinclair | 1998Nitrogen fixation and nodule permeability to O-2 diffusion are decreased by drought stress. Since gamma-aminobutyric acid (GABA) synthesis is rapidly stimulated by a variety of stress conditions including hypoxia, it was hypothesized that decrea[...]article/chapitre/communication
