Аннотация

The principles of phytomonitoring and its applications in phytophysiology are considered. The experimental installation (phytomonitor), designed for complex investigation of the state and functions of a vegetating plant, was constructed on the basis of a multichannel recording system. The phytomonitor provides for long-term continuous measurements of parameters (up to 20) that characterize the functional state of a plant and environmental conditions. One group of parameters was monitored from the shoot: transpiration, leaf turgor, water flow in the xylem, electric conductance of the stem, stem elongation rate, weight increase, pCO2, temperature, and illuminance. Another set of parameters was monitored from the nutrient solution: pH, pK, pCa, pNH4, pNO3, pCl, pCO2, electric conductance, redox potential, and temperature. Examplary experiments on phytomonitoring were performed with various plant species under steady-state and transient conditions. The potential applications of phytomonitoring are discussed in relation to the following topics: source-sink relationships in the root-shoot system, diurnal and subdiurnal oscillations of ion transport in the roots and transpiration in the shoots, the kinetics of induction and destruction of ion-transporting systems in the roots, interaction of ion and water flows in short-and long-distance transport, plant responses to stress factors, etc.
