Inoculation of plant growth promoting rhizobia in Sudan grass (Sorghum × sudanense (Piper) Stapf cv. Sudanense) and millet (Pennisetum glaucum (L.) R.Br. cv. BRS1501)

Abstract: Rhizobia are able to increase yield of non-leguminous species through production of phyto-stimulating substances. This study aimed to evaluate the inoculation effect of rhizobia UFRGS Lc348 and VP16 on millet and Sudan grass yield and germination, and verify the enrichment effect of culture medium with tryptophan, which leads on the rhizobium/plant interaction. Experiments in vitro and greenhouse conditions were conducted. In millet, the inoculation with VP16 grown in culture medium with or without tryptophan … Show more

“…Biotic and abiotic stresses may affect the effectiveness of the product, making them inefficient in cases such as nutrient-poor or unbalanced soils, salinity, water stress, increasing temperatures, pests and diseases, among others (Bashan et al 2014; Das et al 2017; Khan et al 2017; Thilakarathna and Raizada 2017; Samago et al 2018). To circumvent these factors, several studies have been addressed to gain better knowledge on the intrinsic properties of PGPB, seeking at understanding their optimum growth conditions and interaction with the host plants (Flores-Félix et al 2018; Goulart-Machado et al 2018; Jiménez-Gómez et al 2018). Efforts have also been applied to improve the efficiency of microorganisms already available and in the identification of new elite strains to be used as inoculants under unfavorable and stressful environmental conditions, such as areas frequently experiencing drought, soils with low nutrient availability or with salinity, among others (Benidire et al 2017; Koskey et al 2017; Youseif et al 2017).…”

“…Posteriormente, en cabina de flujo laminar los nódulos fueron macerados por separado con un bastón de vidrio en tubos de ensayo estériles. La suspensión obtenida de los nódulos macerados se inoculó en placas de Petri con medio de cultivo de levadura manitol con rojo congo (LMR) en cabina de flujo laminar utilizando el método de la gota y dispersión por estrías [14]. Seguidamente, las placas fueron incubadas a 28ºC ± 2 durante 10 días.…”
