A new method for measurement of hydraulic conductivity and elastic coefficients in higher plant cells using an external force

摘要: A small external force is used to produce deformation of the cells and an increase in internal hydrostatic pressure onion epidermis cells. The subsequent change cell layer thickness measured as a function time. theory developed show that, for sufficiently forces, this measurement provides enough information determine membrane hydraulic conductivity elastic modulus, some results are given. This method should be applicable sections containing several layers from other kinds higher plant tissue.
