GERMINACIÓN DE SEMILLAS DE 32 ESPECIES DE PLANTAS DE LA COSTA DE GUERRERO: SU UTILIDAD PARA LA RESTAURACIÓN ECOLÓGICA

Abstract

  We present the results of different
germination tests for 32 species of plants that
potentially could be used for the recovery of
degraded lands in the coast of Guerrero. The
experimental treatments consisted in different
forms of scarification and thermal
stratification to break possible physiological
dormancy; the treatments were chosen
considering physical and biological
characteristics of the seeds. For each
treatment, we determined the final proportion
of germinated seeds and estimated the time
required to obtain the germination of the
50% of the total sown seeds, using a
deviance analysis. Additionally, we made a
qualitative estimation of the ease to obtain
seeds in the field. We found that seeds with a
thick coat reached high germination
percentages with mechanical scarification
treatment and slightly less after chemical
scarification; other seeds showed a good
germination after inhibition and thermal
stratification. Insect damage was recorded in
seeds of just three species of plants.
