RUIZ-RAMIREZ, Santiago et al. Germination and vigor of seeds of horticultural species, inoculated with biofertilizers and saline solutions. Rev. Mex. Cienc. Agríc [online]. 2021, vol.12, n.7, pp.1199-1208.  Epub Mar 22, 2022. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v12i7.2539.

This research work was carried out in Tepatitlán de Morelos, Jalisco, at the facilities of the Centro Altos de Jalisco Experimental Field. Seeds of horticultural species (chilaca chili pepper, melon and cucumber) were used inoculated with biofertilizers (Azospirillum brasilenses and Glomus intraradices) and subjected to different concentrations of potassium chloride (KCl). The objective was to evaluate the effect of biofertilizers and KCl on germination and vigor in seeds of horticultural species. The treatments evaluated under laboratory conditions were through the inoculation of biofertilizers, combination of biofertilizers plus saline solution at different concentrations, chemical treatment and absolute control, the above to observe the physiological effect on the seeds through the variables evaluated: standard germination, average plumule length, vigor and dry weight. The information obtained from each of the variables was analyzed by means of a completely randomized design with factorial arrangement and with four repetitions, the experimental unit being the tacos (substrate between paper). Highly significant differences between treatments and variables were detected, this due to the results obtained by inoculation of biofertilizers in combination with saline concentrations, they physiologically promoted the horticultural species under study, being treatments T7 and T8, with better response with respect to the absolute control; that is, they have a positive effect on germination and vigor in the species studied.
