| Popis: | Sorghum is a multipurpose crop that is cultivated worldwide. Plant growth-promoting bacteria (PGPB) have important roles in enhancing sorghum biomass and nutrient uptake and suppressing plant pathogens. The aim of this research was to test the effects of the endophytic bacterial speciesKosakonia radicincitansstrain IAC/BECa 99,Enterobacter asburiaestrain IAC/BECa 128,Pseudomonas fluorescensstrain IAC/BECa 141,Burkholderia tropicastrain IAC/BECa 135 andHerbaspirillum frisingensestrain IAC/BECa 152 on the growth and root architecture of four sorghum cultivars (SRN-39, Shanqui-Red, BRS330, BRS509), with different uses and strigolactone profiles. We hypothesized that the different bacterial species would trigger different growth plant responses in different sorghum cultivars.Burkholderia tropicaandH. frisingensesignificantly increased the plant biomass of cultivars SRN-39 and BRS330. Moreover, cultivar BRS330 inoculated with either strain displayed isolates significant decrease in average root diameter. This study shows thatBurkholderia tropicastrain IAC/BECa 135 andH. frisingensestrain IAC/BECa 152 are promising PGPB strains for use as inocula for sustainable sorghum cultivation. |
