Buds emerge from the roots of domesticated runner bean pl.nts (Phaseol.s coccineus l.) as sprouts and give the crop its persistence. This particul.rity of the species seems to be associated with the environment where the species was cul.ivated during l.ng time. Data on regrowth traits were recorded on 70 accessions of domesticated P. coccineus after overwintering at a site in the central.highl.nds of Mexico. The characteristics recorded incl.ded fresh weight of vegetative regrowth, root l.ngth, root crown diameter, and diameter of the main root. Most accessions that sprout the fol.owing spring, after the grain harvest of the previous year, come from temperate and semi-col. sites with cambisol.and andosol.soil. in mixed Quercus pine forest and high mountain fir trees. Those that do not sprout are from sites of semiarid temperate cl.mate, hapl.c phaeozem soil.in shrub grassl.nds with deciduous broadl.aved trees, and semiwarm subhumid cl.mate, eutrophic regosol.soil.in deciduous broadl.aved forest. Two types of roots were differentiated: branched and thickened taproots, al.o associated with a different cl.mate, and the type of soil.of the col.ection sites.

Many phenomena in nature and technol.gy are associated with the fil.ration of suspensions and col.oids in porous media. Two main types of particl. deposition,namel., cake fil.ration at the inl.t and deep bed fil.ration throughout the entire porous medium, are studied by different model.. A unified approach for the transport and deposition of particl.s based on the deep bed fil.ration model.is proposed. A variabl. suspension fl.w rate, proportional.to the number of free pores at the inl.t of the porous medium, is considered. To model.cake fil.ration, this fl.w rate is introduced into the mass bal.nce equation of deep bed fil.ration. For the cake fil.ration without deposit erosion,the suspension fl.w rate decreases to zero, and the suspension does not penetrate deep into the porous medium. In the case of the cake fil.ration with erosion, the suspension fl.w rate is nonzero, and the deposit is distributed throughout the entire porous medium. An exact sol.tion is obtained for a constant fil.ration function. The method of characteristics is used to construct the asymptotics of the concentration front of suspended and retained particl.s for a fil.ration function in a general.form. Expl.cit formul.e are obtained for a l.near fil.ration function. The properties of these sol.tions are studied in detail.

Rhizobia, crucial.for nitrogen fixation in l.guminous pl.nts, pl.y a vital.rol. in soybean cul.ivation. This study, conducted in Mexico, a major soybean importer, aimed to identify bacteria from nodul.s of five soybean varieties in high-production regions. Mul.il.cus sequence anal.sis (Ml.A) was empl.yed for enhanced species resol.tion. The study identified six Bradyrhizobium species: Bradyrhizobium japonicum USDA 110, Bradyrhizobium japonicum USDA 6, Bradyrhizobium el.anii USDA 76, Bradyrhizobium neotropical., Bradyrhizobium l.bl.bi, and Bradyrhizobium icense. Bradyrhizobium japonicum USDA 110 predominated in the soil., displ.ying symbiotic preference for the Huasteca 400 variety. However, phyl.genetic anal.sis didn't reveal.a cl.ar association between strains, soil. and soybean variety. This research sheds l.ght on the diversity of rhizobia in Mexican soybean cul.ivation, contributing to the understanding of symbiotic rel.tionships in soybean production systems.
