| description | Syagrus romanzoffiana (Cham.) Glassm. is a species native to Brazil that is of ecological and aesthetic importance. This study aims to describe the biometric characteristics of S. romanzoffiana fruits and to assess the effects that treatments meant to overcome dormancy and partial drying have on seed germination. For biometric characterization, each repetition consisted of 50 fruits from eight clusters (total, 400 fruits). To evaluate methods for overcoming dormancy, seeds representative of populations were treated by perforation of the operculum; perforation of the operculum and immersion in water for 24 hours; cracking; exposure to fire for three minutes; and non-removal of fibers. There was also a control group. In a second experiment, seeds were partially dried. We determined the proportional moisture content of newly harvested seeds (20.2%) and dried them down to moisture contents of 15.5% and 12.7%. All seeds were subjected to a germination test at 30ºC. The fruits showed biometric variations, with an average of 21.7 mm in longitudinal diameter and 19.7 mm in polar diameter, and a fresh mass of 5.61 g, of which 59.29% was pulp. The highest germination rates and vigor to overcome dormancy occurred after the operculum was perforated and the seeds were soaked in water for 24 hours. The results of the partial drying treatments did not differ sufficiently to discourage dormancy in any significant manner. |
