| ABSTRACT This study aimed to evaluate the efficiency of different removal methods of sarcotesta and their effects on the physiological quality of the seeds. We applied the following treatments: T1 - friction in coarse sand on a sieve; T2 and T3 - immersion in sulfuric acid (98%) for 30 minutes and washing in water, with and without a vernalization for 48 hours in a refrigerator at 4 °C, respectively; T4 and T5 - natural fermentation for 72 hours, with seeds submitted and not submitted to drying in shade for seven days; and T6 - seeds with intact sarcotesta as control. The experiment was carried out in a completely randomized design. For the analysis of the viability and vigor, we used the germination test, germination on first count, germination speed... |
