Growth promotion of Pinus radiata seedlings by soil inoculation and seed pretreatment with the biological control agent Clonostachys rosea

ABSTRACT Twenty-one Clonostachys rosea strains, previously selected by its biocontrol activity higher than 80% against Fusarium circinatum, were evaluated for its ability to promote growth of Pinus radiata seedlings on natural substrate. Stem height, root length, dry weight of stem and roots, and ec...
