Drought. Control. Inoculation of LEANUM seeds

Unlike the previous version of LEANUM, the new proprebiotic also contains signal molecules (SM), which, when inoculated with seeds, transmit an alarm signal to the future plant, artificially simulating the onset of drought. That is, all this happens even before the seeds are sown in the soil. The reaction of vegetative plants to the onset of drought is also enhanced by treatment with a new preparation for vegetative plants (foliar treatment). Accordingly, seeds treated in this way with signal molecules, when placed in the soil, generate primarily a large root as a guarantee of the survival of the entire plant in drought. To do this, the germinating grain secretes an increased amount of root exudates - mucus-like secretions based on complex sugars (exopolysaccharides), which attract soil microbiota, which creates a bacterial cover around the roots, accelerating the predominant growth of the root itself, rather than the above-ground part of the plant. The rhizobial cover in the form of mucus, filled with 97% moisture, 2–3% nutrient medium (matrix in scientific terms), in which bacterial films of various colonies of beneficial bacteria and fungi reliably adhere to the roots, acts together with the plant as a single organic mechanism, and in addition, it itself accumulates additional moisture. As a result, a young plant accumulates 6.5–7.5 times more water than its dry weight, while a plant without such treatment accumulates only 4.5–5 times. The biofilm reliably protects the young plant from soil phytopathogens and attracts soil microbiota to the root area due to the release of “sweet” polysaccharides by the root surface. As a result of the accumulation of moisture by the root, its surface area increases by 40–60% compared to control plants, which increases the chances of the plant to colonize a larger area, which will certainly affect both survival during prolonged drought and increased plant productivity. The main thing in such an approach is that the plant is almost guaranteed the opportunity to survive the dry period, reducing the risks of financial bankruptcy for the land user.
