Minimizing or neutralizing the effects of environmental stresses on crop plants, protecting against pests and diseases, and at the same time ensuring optimal plant growth and development are currently the most important tasks faced by growers and plant producers around the world. Nowadays, the goal is to limit the use of chemicals as much as possible to protect the environment and improve the quality of food. The interest in the use of beneficial rhizosphere microorganisms is becoming global, as it can represent an environmentally friendly alternative to chemicalization in the era of threats to crop cultivation in the modern world (climate change, drought, salinity, introduction of plant pests).

Przeprowadzono doświadczenie szklarniowe w celu oceny wpływu grzybów mikoryzowych na wzrost kukurydzy, przy założeniu, że grzyby te mogą zwiększać odporność roślin na stres suszy. Badania wykazały, że zasiedlenie korzeni kukurydzy przez grzyby arbuskularne zwiększyło oddychanie glebowe mierzone po regeneracji roślin oraz polepszyło funkcjonowanie aparatu fotosyntetycznego i zwiększyło wydajność wykorzystania wody, zarówno podczas stresu suszy, jak i po regeneracji roślin, a w efekcie zwiększyło świeżą masę roślin.

Corn grains (Kresowiak variety) were coated with a com. mycorrhizal fungi before sowing in a 2-parameter pot expt. An arable humus soil (pH 5.5) was used under drought stress (soil humidity 5–8%). Use of mycorrhizal fungi resulted in an increase in fresh mass of the total plants, transpiration index, CO2 assimilation and photosynthetic water use efficiency both under the drought stress and after plant regeneration.

Collembola often play an important controlling role in the interrelationship between arbuscular mycorrhizal fungi (AMF) and host plants. However there are little data to prove AMF dispersing ability of Collembola. In our experiment Folsomia candida (Willem) did not consume the spores of Glomus mossea (Nicol. and Gerd.) and G. intraradices )Schenck and Smith), but Sinella coeca (Schott) consumed 45% of the G. mossea spores and 71% of G. intraradices spores. Both species were able to disperse mycorrhiza in the soil, but the efficiency of dispersal was different. F. candida carried the infection more effectively than S. coeca, in spite of the fact that F. candida did not consume the spores in the food choice experiment. The total plant biomass was 23% higher in the presence of F. candida and 8.5% higher in the presence of S. coeca then in the control treatment without Collembola. The water content of the plants was also a little higher in the presence of both Collembola species (about 10%) than that of the control plants, but this difference was not statistically significant. Collembola improved the dispersion of the AM fungi, therefore enhanced the nutrient and water uptake of the plant.
