ELIMINACIÓN DE LA DORMICIÓN DE SEMILLAS DE CAPULÍN Prunus serotina ssp. capuli {Cav.), MEDIANTE EL REMOJO Y SECADO
Keywords:
Germinated, dormancy, soaking and drying, capulinAbstract
In paper sowing, intact "capulin" stones germinated after more than 20 days, with 60 percent. When opening the woody endocarp where they are, this percentage increased in 20 percent; this percentage was lost when the suture was sealed wíth vaseline. Dormancy was wholy overcome with endocarp remotion, since almost ali the seeds showed their radicle in less than ten days. This behaivour was similar when the embryoes were extracted.
This reactions were attributed to the presence of inhibilors in seeds and endocarp, since intactstones and seeds extracts as those from the endocarp free seeds, limited significately the growth ofwheat coleoptile.
In sowing over paper and soil, two and four cycles of soaking and drying to the "capulin" stones with intact endocarp promoted germination more than continuos soaking from one to four days; the stimulation obtained was similar to the hand cutopen stone.
