   <abstract xml:lang="ru">
    <p>В работе представлен технический и методический подход для исследования скорости роста растительных клеток под воздействием внешнего гидростатического давления, как одного из важных термодинамических параметров роста. Данный подход включает использование оригинальной камеры давления, адаптированной под оптический микроскоп и газовую систему для подачи и сброса давления. В работе приведена подробная конструкция и чертёж разработанной камеры, а также схема проведения эксперимента с её использованием, включая описание дополнительных технических и программных средств. Использование данной камеры позволяет исследовать изменение размеров и скорость роста растительных клеток в динамике непосредственно при изменении внешнего давления в диапазоне от 0,1 до 1 МПа. Представлены некоторые результаты исследования воздействия повышенного гидростатического давления на рост растительных клеток, полученные с использованием данного технического и методического подхода. В частности, на примере корней проростков кукурузы показано, что повышение внешнего давления до 0,3 МПа вызывает ускорение роста растяжением в клетках эпидермиса корня. Оценены перспективы дальнейшего использования разработанной системы применительно к исследованиям ростовых процессов в растительных тканях.</p>

    <p>The work presents a technical and methodological approach for studying the growth rate of plant cells under influence of external hydrostatic pressure, as one of the important thermodynamic growth parameters. This approach involves the using of original pressure chamber adapted to optical microscope and gas system for supplying and releasing pressure. The paper contains the detailed design and drawing of the chamber, as well as the scheme of experiment conducting with chamber using, including a description of additional hardware and software. The use of this chamber makes it possible to investigate the changes in the size and growth rate of plant cells in dynamics directly with the change in external pressure in the range from 0,1 to 1 MPa. The main results of the external hydrostatic pressure impact study, obtained using this technical and methodological approach, are presented. In particular, on example of the roots of corn seedlings, it was shown that increasing of external pressure up to 0,3 MPa causes acceleration of elongation growth in the cells of the root epidermis. Prospects for the further using of the developed system as applied to studies of growth processes in plant tissues are presented.</p>
