Physiology of olive nutrition I: factors affecting proton extrusion by roots of intact olive plants
The ability of roots of intact olive plants to change the pH of the external medium was studied. When the roots were put in contact with 1 mM CaSO4, a basification was recorded. The same behaviour was observed in the ...
Soil humic substances stimulate proton release by intact oat seedling roots
The effect of a soil humic fraction (HS) on proton extrusion into delonized water by intact oat seedling roots was studied. In the presence of HS, at concentration of 10 μg organic carbon (C) mL-1, a clear stimulation of ...
