“…Pre-sowing seed treatment, as a rule, should provide increased germination, germination energy and removal of phytopathogens. This is relevant when obtaining root exudates in aquatic cultures in modern biotechnology (Azeez et al, 2018;Wolny et al, 2018;Lechowska et al, 2019). Removal of epiphytic microorganisms is a rather difficult task.…”

“…The study of the relationship between growth processes and the qualitative and quantitative composition of root exudates is important to understand the mechanisms of autoregulation of growth and development of plants, and to obtain root exudates that are used in biotechnology (Bozhkov et al, 1996;Kossmann, 2012;Li et al, 2013;Azeez et al, 2018).…”

“…The carbohydrate content in the composition of root exudates was determined according to the Molish method (Masuko et al, 2005), and the content of free amino acids was determined using the ninhydrin method as described previously in our works (Azeez et al, 2018). Carbohydrate content was expressed in μg glucose/100 grains, and amino acid content in μg glycine/100 grains.…”

“…An analysis of the functioning of the root excretory system after pre-sowing seed treatment, which provides a hormesis effect in relation to the seedling growth rate, plays a vital role in the development of root biotechnologies in order to obtain biologically active compounds (Belz et al, 2011;Kossmann, 2012;Azeez et al, 2018).…”

The importance of studying pre-sowing seed treatment lies in the possibility of regulating the rate of seed germination, the intensity of their growth and obtaining root exudates in biotechnology. The effect of three pre-sowing treatment methods was examined (control – washing with running water; the first method – washing with 0.05% sodium permanganate solution; the second method – 30 seconds in 70% ethyl alcohol (C2H5OH) and 30 minutes in 5% sodium hypochlorite (NaOCl); the third method – 5 minutes in 70% C2H5OH and 40 minutes in 5% NaOCl) on the growth rate, germination rate, excretion rate of seeds of wheat and peas and composition (of protein, carbohydrate, amino acid content) of root exudates from the first to the third day of growth in order to obtain root exudates. It was revealed that the same pre-sowing treatment of wheat and pea seeds has a different effect on the rate and variability of seedling growth from the first to the third day, as well as on the qualitative and quantitative composition of root exudates. It was shown that pre-sowing treatment of wheat and pea seeds for 5 minutes with 70% ethanol followed by treatment with sodium hypochlorite (a “hard” treatment method) accelerates seedling growth and seed germination. This method of treatment reduces the intensity of excretion of root exudates and composition in wheat, but it increases the intensity of excretion in peas. The discovered effects can be explained by hormesis. Additionally, the third method of pre-sowing seed treatment can be used in root technologies for obtaining root exudates.
