Abstract:
The effectiveness of scarification treatments in the promotion of germination of Bauhinia divaricata was determine to suggest an effective and practical method for breaking seed dormancy. Seeds were collected on March 2010, obtained from disturbed forests and tested with different exposition times (0, 7, 15, 20 and 30 min) by their immersion into sulfuric acid during April and May 2010, assays were done in the Botanical Garden of the Universidad Autonoma del Carmen, day/night regime of 32/18°C was taken into consideration along with a 12 h photoperiod. The germination was observed daily early in the morning during 30 days. All treatments started their germination three days after the beginning of the experiment and reached their maximum value between 25 and 30 days after the exposition. Seeds treated with sulphuric acid, responded positively in all cases but, the immersion in acid for 15 or 20 min were the treatment that showed the best results, for this reason these treatments are recommended to improve and to efficient the germination of seeds of this species.
