| Erythrina speciosa is specie suitable for forest recuperation programm. As its seeds coats are impermeable to water absorption, the aim of this work was to study the change of biometric characters during seed germination and analyse the physiological quality of E. speciosa seeds from different sources. Therefore, seeds were collected from Capão Bonito and Ribeirão Grande, two municipilties of São Paulo State, Brazil, and were scarified. For each replicate were used 15 seeds. The germination test was conducted at 25 °C with photoperiod of 12 hours, using vermiculite packed in seedling boxes. We evaluated the germination percentage, germination speed index, seedling stem diameter and number of leaves. The results showed that the seeds of different sources... |
