PHYSICAL AND CHEMICAL TREATMENTS FOR OVERCOMING DORMANCY IN Butia capitata (MARTIUS) BECCARI SEEDS
Keywords:
Arecaceae, pyrene, scarification, gibberellinsAbstract
The aim of this study was to assess the effect of pre-germination treatments for overcoming dormancy in Butia capitata seeds. The experiment was conducted in a randomized blocks design, in a 3x3 factorial scheme (mechanical treatments x immersion substances), with 20 seeds per plot and four replications. For mechanical treatments, seeds with endocarp (pyrene), seeds without endocarp, and scarified pyrenes were used, whereas, for the immersion substances, gibberellic acid, water, and the control (without immersion) were used. The emergence of seedlings began within 51 days, in pyrenes scarified and treated with gibberellic acid. The difference between the first and last count was 190 days. There was no interaction effect for the characteristics assessed, except for the mechanical treatments. It was possible to conclude that the scarified pyrenes showed a higher performance for most characteristics assessed: emergence percentage, emergence speed index, length, and root fresh and dry mass.KEY-WORDS: Arecaceae; pyrene; scarification; gibberellins.
