Influence of ozone on germination and germinating energy of winter wheat seeds

Abstract

Obtaining high quality crop yields is one of the most important economic problems of Russia. The yield of agricultural crops depends on the quality of the sowing material and its preparation for sowing. Currently modern technologies of processing seed based are used on applying various types of physical factors. Positive experiences on the use of the magnetic field, infrared and laser radiations, the currents of ultra-high frequencies to increase germination and seed growth are known. Unlike traditional methods of presowing treatment of seeds with chemicals, electrical methods are environmentally clear and do not have negative side effects on plants. One of the most promising methodsfrom an environmental point of view is ozonation. Scientists have determined that the ozonized air contributes to the improvement of sowing qualities of seeds. However, optimization of ozone treatment with the aim of increasing energy of growth and germination as the main indicators of sowing qualities requires improvement. In Educational and scientific testing laboratory of the Stavropol State Agrarian University for several years the research to examine the impact of environmentally safe ways on increasing the sowing qualities of seeds of grain crops was conducted. In particular, there was a twofactor experiment conducted on the influence of ozone on the improvement of the sowing qualities of seeds of winter wheat. Seed treatment was carried out on an industrial ozonator "Ozone-60P". Determination of ozone concentration was performed using a gas analyzer "Cyclone-5.41". It is proved that pre-treatment with ozone leads to increased germinating energy and seed germination. The article presents the optimal parameters of seed treatment of winter wheat with ozone to promote their sowing qualities.

An In Situ FTIR Study of DBD Plasma Parameters for Accelerated Germination of Arabidopsis thaliana Seeds

“…Ozone and NO x species are known to affect seed dormancy and germination [ 17 , 18 , 19 , 20 ]. However, in this study, there was no clear conclusion as to whether any particular molecule was responsible for the accelerated germination.…”

Mechanisms of Plasma-Seed Treatments as a Potential Seed Processing Technology

“…In some cases, plants like mung beans are not able to overcome ozone stress with their antioxidant defenses [152]. On the other hand, ozone has been used to enhance seed germination [153] or improve fruit quality [154]. Ozone seemingly has an ambivalent role that is dependent on the concentration and length of treatment [155] as it is the case for many other treatments i.e., hormone, nanoparticles, heat.…”

Modes of treating pre-sowing grain seeds with ozone

“…At the same time, there is an increase in the yield of various agricultural crops. Ozone has a number of specific properties that benefit its wide use in various agricultural operations [4][5][6].…”
