| Summary: | This study investigated the methodology that best expresses the germination and quality of Allophylus edulis seeds, analyzing different substrates. Initially, there was the characterization of thebatch by Weight of Thousand Seeds (PMS), Water Content (TA) and Electrical Conductivity (CE). In theGermination Test were evaluated the following treatments (substrates): on blotting paper (PMB), on filterpaper (SPF) on (SA) and among sand (EA), on (SV) and among vermiculite (EV) and paper roll (RP), being conducted ina germination chamber Mangelsdorf (25 °C). Data were expressed in percentages of normaland abnormal seedlings, dead seeds and firm and also, it was assessed the speed of germination index. It was used a completely randomized design with four replicates per treatment. The substrates among sand (SA) and among vermiculite (EV) were the most suitable for the germination test and the first countof normal seedlings can be made between 12 and 15 days and the final 24 days after sowing. |
