摘要

目标。以枯草芽孢杆菌(Bacillus subtilis IMB -7023)和葡萄固氮菌(Azotobacter vinelandii IMB -7076)为基础,研究复合菌制剂Azogran对栽培植物种子发生初期的影响。方法。微生物(微生物的培养是在周期性培养条件下进行的——a . vinelandii IMB -7076在Ashby液体消化培养基中,枯草芽孢杆菌IMB -7023在含葡萄糖的矿物培养基中;通过连续稀释后在相关培养基表面播种的方法测定悬液中活细胞的数量,生理(用不同稀释度的生物修复悬液接种种子),统计学。结果。混合菌剂偶氮氮氮对乌克兰品种荞麦、波多利安卡品种冬小麦和玛哈丽塔品种普通皮的发芽率、发芽率、芽长和芽重均有显著提高,与对照(水处理)相比效果显著。荞麦和小麦在植物个体发生初期效果最好。以1:10和1:10的比例对生物修复悬浮液进行水稀释时,接种的积极效果更为明显,说明细菌大量生产生物活性物质。用颗粒状复合细菌制剂Azogran水悬浮液处理不同玉米品种的种子,对芽苗菜的发育有积极的影响,也有助于减少植物病原微菌对芽苗菜的伤害。结论。复合菌制剂偶氮格兰对所研究植物的发芽能、发芽率和芽质量均有积极影响,可降低微菌对种子的损害程度,推荐用于农业植物播种前的土壤种子处理。

INFLUENCE OF THE COMPLEX BACTERIAL PREPARATION AZOGRAN ON THE DEVELOPMENT OF SPROUTS OF CULTIVATED PLANTS
Objective. To investigate the effect of seed treatment of cultivated plants with the complex bacterial preparation Azogran (based on Bacillus subtilis IMB B-7023 and Azotobacter vinelandii IMB B-7076) on the initial stages of ontogenesis under laboratory conditions. Methods. Microbiological (cultivation of microorganisms was carried out under periodic culture conditions — A. vinelandii IMB B-7076 in Ashby liquid digest medium, Bacillus subtilis IMB B-7023 — in a mineral medium with glucose; the number of viable cells in suspensions was determined by the method of serial dilutions followed by sowing on the surface of the relevant agarized media), physiological (with different dilutions of biopreparation suspensions for seed inoculation), statistical. Results. Bacterization of Ukraina variety buckwheat seeds, Podolianka variety winter wheat and Marharyta variety common tare with a liquid complex bacterial preparation Azogran had a positive effect on germination energy, germination, sprout length and their weight compared to the control (water treatment). The best results at the initial stages of plant ontogenesis were found for buckwheat and wheat. The positive effect of inoculation was more pronounced when diluting the biopreparation suspension with water in ratios of 1:10 and 1:100, which indicates intensive production of biologically active substances by bacteria. Treatment of seeds of different corn varieties with an aqueous suspension of the granular complex bacterial preparation Azogran had a positive effect on the development of sprouts, and also contributed to the reduction of their damage by phytopathogenic micromycetes. Conclusion. The complex bacterial preparation Azogran has a positive effect on the energy of germination, germination and the weight of sprouts of the investigated plant species, reduces the degree of seed damage by micromycetes and is recommended for the treatment of seeds of agricultural plants before sowing in the soil.
