Palabras clave: pregerminative treatment, combinations, germination, growth variables

Resumen

The objective of this research project was to analyze the effects of the
application of pregerminative stimulants and different types of
substrates in the germination of Gmelina arborea, in the nursery stage.
For the application of the project, 3.5 pounds of melina seeds were
purchased to which the respective pregerminative treatment was
applied, prior to the sowing of the same ones, establishing a total of
1,440 seeds in 36 tubes of 40 seeds per tube. With three repetitions,
three pregerminative treatments were used (nitric acid and distilled
water, hot water and cold water) on G. arborea Robx seeds, with three
combined substrates (orchard soil + sand, common soil + UTEQ fertilizer,
common soil + rice husk), plus the control to which no treatment was
applied, since it served as a control, but it was sown on combined
substrates. After two weeks of germination data collection, the growth
variables were measured during 8 weeks of height, number of leaves,
stem diameter, length and width of the leaf and length of the root, the
latter only once. The work was carried out in the experimental farm "La
Represa" owned by the State Technical University of Quevedo. The
pregerminative treatments applied to Gmelina arborea Robx seeds,
varied in differences on germination between treatments, in addition to
the different combined substrates in which it was put to germinate,
differences were evidenced in how many growth variables. Giving us as
results several similarities between treatments and substrates.
