<description xml:lang='en' descriptionType='Abstract'><p>Climate change, frequent droughts, abrupt changes in weather conditions during the<br />season, as well as in connection with this the growth of phytopathogenic diseases, have become<br />significant problems for the cultivation of grain crops. One of the methods that allow<br />withstanding adverse weather conditions is the treatment of seeds before planting. It is<br />directed not only at increasing and accelerating germination, but also at obtaining a high and<br />qualitative harvest.<br />Currently, various methods of seed processing are known using natural biologically active<br />microbial preparations, especially from yeasts. Results about the influence of preparations of<br />levurian origin on the indices of plant growth and development are described in the literature,<br />but specifically about the effect of mannoprotein preparations in this regard, data have not been<br />found.<br />In this context, the research aimed to test the mannoprotein preparation LB-MP in the<br />concentration of 10 mg/mL at the ability to stimulate seed germination, growth, and<br />development of Triticosecale Wittm plants, Ingen 40 variety.<br />The biologically active preparation based on yeast biomass from brewing waste from the<br />Kellers brewery, Budeshti was obtained through several stages: autolysis of yeast biomass with<br />sodium phosphate buffer, subsequent processing of the remaining biomass with 1N NaOH for<br />2 hours at a temperature of +80 &plusmn;5 &deg;C, obtaining the alkaline extract and sedimenting the<br />mannoproteins with ethyl alcohol.<br />The seeds were treated with LB-MP mannoprotein preparation in the concentration of 10<br />mg/mL and its distilled water solutions of 0.33; 0.5; 1; 2 and 10 %/V. Distilled water was served<br />as a control. The experiments were performed at room temperature +23&ndash;24 &deg;C, in three<br />repetitions. Three days after germination, the following parameters were evaluated: the formed<br />number of roots, the length of the roots and stem, the dry mass of the roots and stem of each<br />plantule.<br />The obtained results indicate that the treatment of seeds with LB-MP bio preparation in<br />the concentration of 10 mg/mL increases the number of roots by 6 %, the length of the roots<br />by 10 %, the dry mass of roots and stems by 4&ndash;11 % compared to the control sample.<br />The stimulating effect was also established in the case of seed processing with the<br />aqueous solution of the LB-MP preparation in the concentration of 0.5 %. The results indicate<br />a 10 % increase in the number of roots, a 5 % increase of stem length, a dry mass of roots and<br />stems by 6&ndash;10 %, compared to the control variant. The other concentrations of the preparation<br />had a neutral influence, the values of the studied indices oscillating at the control level or had a<br />negative effect.<br />Thus, taking into account the established effect and the fact that the preparation can be<br />obtained at a convenient price from the waste of the beer industry, research on the use of yeast<br />preparations as stimulants of crop plants is perspective.</p></description>
