Selective effects of victorin on growth and the auxin response in Avena.

abstract：:Water storage is thought to play an integral role in the maintenance of whole-plant water balance. The contribution of both living and dead cells to water storage can be derived from rehydration and water-release curves on excised plant material, but the underlying tissue-specific emptying/refilling dynamics remain un...

abstract：:Computing techniques are used to simulate the course of uptake of K(+), Na(+), and Cl(-) by low-salt roots. Measurements of the fluxes of these ions in high-salt roots are used to calculate membrane permeabilities, which are then used to calculate cell uptake. In this way it is possible to test the predictive value of...
