The plant growth promoting capability was evaluated by IAA (Indole-3-acetic acid) production and phosphate solubilization at 5, 14 and 28°C. 50% of FLDB and Pseudomonas sp. strains showed IAA production and phosphate solubilization at 28 °C. Furthermore, B2, Ps31, 5A and Ps42 strains improved maca seeds germination percentage against Control treatment, under dark conditions and temperatures ranging between 15 and 18°C. The BOX-PCR profiles analyses revealed a genetic variability in each studied bacterial group. The PGPR potential showed by the isolated strains makes them a promising strains for yield and nutrient content improvement in maca roots.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengBioMicroWorldinfo:eu-repo/semantics/openAccessPerúBacteria-1Lepidium meyenii W.-1https://purl.org/pe-repo/ocde/ford#1.06.01-1Characterization of rhizospheric bacteria isolated from maca (Lepidium meyenii W.) in the highlands of Junin-Peruinfo:eu-repo/semantics/conferenceObjectreponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC20.500.12390/1138oai:repositorio.concytec.gob.pe:20.500.12390/11382024-05-30 16:01:23.311http://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="3878bfc5-900e-4308-a30c-58c5090eaaa4"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>Characterization of rhizospheric bacteria isolated from maca (Lepidium meyenii W.) in the highlands of Junin-Peru</Title> <PublishedIn> <Publication> </Publication> </PublishedIn> <PublicationDate>2011</PublicationDate> <ISI-Number>394555900005</ISI-Number> <Authors> <Author> <DisplayName>Davila, DZ</DisplayName> <Person id="rp03211" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Macalupu, JT</DisplayName> <Person id="rp03213" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Wong, MG</DisplayName> <Person id="rp03210" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Porras, WP</DisplayName> <Person id="rp03214" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Bautista, MM</DisplayName> <Person id="rp03212" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Gutierrez, KO</DisplayName> <Person id="rp03215" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>BioMicroWorld</DisplayName> <OrgUnit /> </Publisher> </Publishers> <Keyword>Perú</Keyword> <Keyword>Bacteria</Keyword> <Keyword>Lepidium meyenii W.</Keyword> <Abstract>The aim of this study was to characterize the bacterial diversity associated with maca rhizosphera for their future application as inoculants in the stressing conditions of maca breeding. 108 free living diazotrophs, 29 actinomycetes, 109 Pseudomonas sp. and 109 Bacillus sp. strains were obtained.
