Abstract

Cette invention décrit l’obtention d’un biostimulant à base de 3 souches bactériennes pour booster la résistance des plantes aux stress hydrique et osmotique. Ces bactéries sont capables d’augmenter le potentiel hydrique des sols par le biais de dégradation des cires (bdc) qui enrobent les composantes des sols et réduisent la capacité de ces derniers à stocker suffisamment d’eau pluviale et/ou d’irrigation. En plus, ces bactéries aident les plantes à mieux maitriser l’économie de l’eau via une nutrition potassique optimale et permanente (bsk). Ces trois bactéries (bdc + bsk) sont codées n1, n4 et n3 et idenfiées(n1 = streptomyces acrimycini n4= streptomyces mutabilis et n3= polyangium brachysporum. Cette invention décrit également une nouvelle formulation d’inoculum bactérien basée sur l’optimisation de certaines propriétés biologiques chez ces bactéries (n1, n4 et n3) à savoir leurs propriétés à augmenter la capacité de rétention d’eau par les sols et à solubiliser et à mobiliser les formes du potassium pour la plante à partir de formes inorganiques complexes qui ne sont pas accessibles à la plante sans son partenaire microbien(bcd et bsk). En incluant ensemble des propagules de ces bactéries et la perlite comme matrice, la capacité des (bdc et bsk) à augmenter la capacité éponge des sols à et à solubiliser les formes insolubles du potassium et les rendre accessibles à la plante seront accrues. De ce fait, le rôle du partenariat (bdc et bsk- plante) sur le développement de la plante hôte sera optimisé en combinant intimement l’impact de ces bactéries sur la plante directement (maitrise de l’absorption, conduction et la transpiration) et indirectement (disponibilité de l’eau dans les sols de façon uniforme, par altération des composantes qui causent sa perte par le lessivage, évaporation).This invention describes the production of a biostimulant based on 3 bacterial strains to boost the resistance of plants to water and osmotic stress. These bacteria are capable of increasing the water potential of soils through the degradation of waxes (bdc) which coat the components of the soil and reduce the capacity of the latter to store sufficient rainwater and/or irrigation water. In addition, these bacteria help plants to better control water saving through optimal and permanent potassium nutrition (bsk). These three bacteria (bdc + bsk) are coded n1, n4 and n3 and idenfied (n1 = streptomyces acrimycini n4 = streptomyces mutabilis and n3 = polyangium brachysporum. This invention also describes a new bacterial inoculum formulation based on the optimization of certain biological properties in these bacteria (n1, n4 and n3) namely their properties to increase the water retention capacity of the soil and to solubilize and mobilize the forms of potassium for the plant from complex inorganic forms which are not not accessible to the plant without its microbial partner (bcd and bsk) By including together propagules of these bacteria and perlite as a matrix, the capacity of (bdc and bsk) to increase the sponge capacity of soils to and to solubilize forms potassium insolubles and make them accessible to the plant will be increased.Therefore, the role of the partnership (bdc and bsk-plant) on the development of the host plant will be optimized by intimately combining t the impact of these bacteria on the plant directly (control of absorption, conduction and transpiration) and indirectly (uniform availability of water in the soil, by altering the components that cause its loss through leaching, evaporation).
