Changes in Vascular Tissues and Productivity of Buckwheat Plants after Impulse Pressure Treatment

Abstract

Osmotic pressure, pressure gradients in the phloem, and mechanical forces influence different processes in plants. We have proposed the method of pre-sowing seed treatment by impulse pressure generated by a shock wave. It is possible to use the shock wave for different precision purposes due to the excellent parameter control that determine the intensity of the influence. Buckwheat (Fagopyrum esculentum Moench., cv. Saulyk) plants were treated by impulse pressure. The purpose of this work was to study following physiological processes, such as growth of plants, and development of phloem and xylem, which promote crop increases in buckwheat plants, treated by impulse pressure. The changes in the development of conductive tissues provided the growth of leaves and the redistribution of photosynthates to inflorescences and fruits. So, these experiments demonstrated that the total fruit weight increased at plants treated by 11 MPa, exceeding the control by 22.6%. Hence the treatment of seeds by impulse pressure provided more favorable conditions for the supply of forming fruits with photosynthates.
