Dynamic changes in root hydraulic properties in response to nitrate availability.

abstract：:The effect of water stress on stomatal closure in sunflower plants has been found to be dependent on K(+) nutrient status. When plants with different internal K(+) content were subjected to a water-stress period, stomatal conductance was reduced more markedly in plants with an adequate K(+) supply than in K(+)-starved...
