Identification and Evaluation of Trichodermaspp Native, Present on eroded soils in Tetela de Ocampo, Puebla-Mexico

摘要

Is reported the isolation and identification of 9 native strains of Tetela de Ocampo Puebla-Mexico, pH ranges from 5.3 to 6.8, mainly related to the pinegrowth rate of the strains according to the nomenclature of the collection site: TS1P1, TS1P2, TS1P3, CS2P2, PS3P1, P3P3, SS4P2, RS5P2 and RS5P2 in PDA culture medium, where the strain had the highest TS1P1 growth rate of 3.1 mm / day and a growth rate of 4.0 mm / day, followed by strains TS1P2 with 2.9 mm / day and 3.7 mm / day, CS2P2 with 3.2 mm / day and 4.0 mm / day and underrepresented by strain PS3P1 with 2.4 mm / day and 3.5 mm / day test was applied Tukey's multiple comparison ( = 0.05) for comparing treatmentrate development according to their degree of soil erosion.
