Abstract

The effect of the introduction of a non-ionogenic surfactant Polysorbate 20 into a sorption preparation (CB-H-BYA) on the structure of sorbent layers formed on the surface of spring wheat seeds during their pre-sowing treatment has been studied using electron microscopy. According to the results, an increase in the efficiency of sorption preparations containing Polysorbate 20 is based on an intensification of the bentonite aggregate disintegration into individual montmorillonite particles and a formation of more dense protective sorption layer providing a better protection of seeds against allelotoxins on the seed surface. The introduction of non-ionogenic surfactants into the preparation increases a sorption capacity of a bentonite–humus complex that results in a decreased gibberellin activity in a solution. Therefore, to achieve the maximum physiological activity of gibberellin in a preparation solution, it is necessary to increase its concentration from 100 to 300 mg/L. As a result, the stimulating effect increases from 36 to 55%.

含非离子表面活性剂的吸附刺激性制剂用于播前种子处理的效率提高的性质

摘要

使用电子显微镜研究了将非离子表面活性剂聚山梨酯20引入到吸附制剂（CB-H-BYA）中对春小麦种子预播过程中形成的吸附剂层结构的影响。 。根据该结果，包含聚山梨酯20的吸附制剂效率的提高是基于膨润土聚集体崩解成单个蒙脱土颗粒并形成更致密的保护性吸附层，从而为种子提供了更好的保护，使其免受种子上的化感毒素的影响。表面。在制剂中引入非离子表面活性剂可提高膨润土-腐殖质复合物的吸附能力，从而降低溶液中的赤霉素活性。因此，为了在制剂溶液中获得最大的赤霉素生理活性，有必要将其浓度从100 mg / L增加到300 mg / L。结果，刺激效果从36增加到55％。
