Treatment of spring wheat seeds by ozone generated from humid air and dry oxygen

Abstract

Lazukin A., Serdukov Y., Pinchuk M., Stepanova O., Krivov S., Syubushkina I. (2018): Treatment of spring wheat seeds by ozone generated from humid air and dry oxygen. Res. Agr. Eng., 64: 34-40.The paper presents an analysis based on conflicting data regarding the results of the treatment of soft spring wheat seeds by ozone generated from humid air and dry oxygen. Morphological characteristics of treated seeds (the length of a sprout, the total length of roots and the sprout-to-root ratio), 7-day germination ability along with the extent of 7-day-old seedlings contamination are considered in terms of ozone concentrations. The experiments were conducted using the wheat seeds of 2013 and 2014 yields. For the same concentrations of ozone, morphological characteristics of treated seeds and efficiency of seed surface treatment changed similarly for both ways of ozone production. However, the efficiency of seeds treatment and stimulation of seeds germination with ozone are not correlated; and the germination ability of the seeds is not changed after ozone treatment.

Physiological potential and health of peanut seed treated with ozone

“…A previous study evaluated the physiological quality of maize seed soaked in ozonated water at a concentration of up to 30 mg L − ¹ for 120 min and observed no differences in the physiological potential of seed (Maximiano, Carmona, Souza, Alencar, & Blum, 2018). In wheat, authors found no differences in primary root elongation of seed treated with O 3 , but observed changes in root and shoot length (Lazukin et al, 2018).…”

In wheat, authors found no differences in primary root elongation of seed treated with O 3 , but observed changes in root and shoot length (Lazukin et al, 2018). Conversely, in sunflower, whose chemical composition is more similar to that of peanut, authors observed that O 3 administered in seed for 60 min at 1741 ppmv and 0.24 g h -1 increased the number of normal seedlings at the end of the germination test (Rodrigues et al, 2015).…”

Surface disinfection of wheat kernels using gas phase hydroxyl‐radical processes: Effect on germination characteristics, microbial load, and functional properties

“…Nevertheless, the sprout growth for all samples was still shorter than the kernel length itself after 40 h of sprouting, which is in agreement with the definition of sprouted wheat by the Cereals and Grains Association (AACC‐I, 2008) (Benincasa et al., 2019). Numerous reports regarding the effect of disinfectants on the germination and morphological properties of cereal grains have been published (Chun et al., 1997; Lazukin et al., 2018; Tornuk et al., 2011). In a study conducted by Tornuk et al.…”

Ozone Efficiency on Two Coleopteran Insect Pests and Its Effect on Quality and Germination of Barley

“…The ratio of the root length to the shoot length increased when the seeds were subjected to longer O 3 exposure time, signifying that plants reduce shoot growth and enhance root growth in response to O 3 stress. Alexander et al [64] suggested that the root-to-shoot ratio of spring wheat was increased from increasing O 3 concentration. Plants apportioning more biomass to roots and less to stems when they encounter unfavourable conditions has been previously established [65].…”
