Soil of the parent plant and AMF mix improve Cerrado’s seedlings growth in forest nurseries

The soil microbiota plays an extremely important role in the growth and survival of plants. presence some microorganisms can positively significantly impact tree species, which improve performance seedlings after planting for commercial purposes and/or ecosystem restoration. present study aimed to evaluate initial Hancornia speciosa Brosimum gaudichaudii associated with from parent inoculated arbuscular mycorrhizal fungi (AMF). Four substrates were tested: T1 (control) = Autoclaved dystrophic Red-Yellow Latosol (Aut-dRYL) + autoclaved substrate (Aut-CS); T2 Aut-dRYL Aut-CS inoculum AMF (Mix); T3 plant (SPP); T4 SPP Mix. comprised a mix species Gigaspora decipiens, Rhizophagus clarus, Scutellospora heterogama. Seedling was determined 270-350 days transplanting by measuring following parameters: colonization rate (MC), abundance spores (AS), height (H), stem diameter (D), H/D ratio, volume roots (VR), dry matter shoot (SDM), (RDM), total (TDM), / root ratio (SDM/RDM), (H/SDM), Dickson quality index (DQI). results showed that addition improved DQI seedlings, while minimally changed both DQI. use symbiotic nursery Brazil is scarse due difficulty acquiring these lack commercialization specific isolates native Cerrado biome. evaluated naturally occurring areas as source inoculum. higher biomass production plants support form inoculation produce H. B. gaudichaudii.
