Adsorption laser meter of water transport velocity in capillary systems of a plant

Resumo

The article provides the results of measurements of the velocity of the upward water flow in capillary xylem bundles by laser sounding for cucumber plants (hybrid TSHA-575). An adsorption laser meter of water flow velocity in plants was developed. We showed experimental and calculated dependences of linear velocity of xylem flow on the level of gradients of bioelectric potentials along the stem of a plant. Comparative analysis of the obtained experimental results with the model was carried out.
