Abstract

The influence of biosurfactants of trehalose lipid nature (R. erythropolis Au-1) and rhamnolipid nature ( Pseudomonas sp. PS-17) on the efficiency of the absorption of K+ and Ca2+ ions and plants growth was studied. The seeds of soybean, wheat and sunflower after the pre-sowing treatment by the biosurfactants solutions were grown on a liquid nutrient medium. The residual contents of K+ and Ca2+ ions in the medium were different for the variants with the biosurfactants and control (water). Based on these parameters, it was possible to value the stimulating effect of the biosurfactants on the plants’ ability to absorb mineral elements from the nutrient medium. The plants after the pre-treatment by the biosurfactants absorbed on 10-40% (trehalose lipids) and 27-61% (rhamnolipid biosurfactants) K+ and Ca2+ ions more than control variants. The growth parameters of plants were increased on 17-24% (trehalose lipids) or 39-77% (rhamnolipid biosurfactants). The experiments with plants (wheat, soya and sunflower) were also conducted in field conditions. The results showed that the trehalose lipid and rhamnolipid biosurfactants provide an increase in crop yields on 19-23% as well as the yield quality. The obtained data allowed to suggest a possible mechanism for the influence of surfactants on the plant growth.
海藻糖脂和鼠李糖脂表面活性剂作为植物生长调节剂
研究了海藻糖脂质(R. erythropolis u-1)和鼠李糖脂质(Pseudomonas sp. PS-17)两种生物表面活性剂对植物K+和Ca2+离子吸收效率及植物生长的影响。大豆、小麦和向日葵种子经生物表面活性剂溶液预处理后,在液体营养培养基上生长。培养基中K+和Ca2+离子残留量随生物表面活性剂和对照(水)的变化而变化。基于这些参数,可以评价生物表面活性剂对植物从营养培养基中吸收矿物元素能力的刺激作用。经生物表面活性剂预处理后的植株吸收的K+和Ca2+离子比对照变体多10-40%(海藻糖脂类)和27-61%(鼠李糖脂类)。海藻糖脂类和鼠李糖脂类生物表面活性剂分别使植株生长参数提高17-24%和39-77%。在田间条件下,对小麦、大豆和向日葵进行了试验。结果表明,海藻糖脂类和鼠李糖脂类生物表面活性剂可提高作物产量19 ~ 23%,同时提高产量品质。获得的数据允许提出表面活性剂对植物生长影响的可能机制。
