Abstract
Mahoe seeds (Talipariti elatum (Sw.) Fryxell) had an erratic germination and frequently very low so with dormancy. Trichoderma spp. has proved its potential to stimulate germination in different plant species, including some other forestry in Cuba. Three different treatments were evaluated and compared with a control to improve germination and the speed of it. They included seeds wetting for 48 hours before starting the assay, seed treatment with Trichoderma harzianum A-34 conidia and the combination of both. The seeds were kept in trays on wet filter paper in an incubator at 30 °C. Wetting the seeds for 48 hours and treating them with T. harzianum increased more than double compared with the control, the other treatments increased in only 10 days, one third the time established for the final evaluation of seeds viability. These results could be introduced in laboratory analysis to reduce the samples stay and seedlings production.
