Seeds from the ends of flamboyant tree pods have higher performance

Some studies have indicated higher quality of seeds from favourable ovule positions in Fabaceae. This may cause non-uniform germination. However, no study regarding this effect has yet been performed in flamboyant tree (Delonix regia) seeds. Therefore, to contribute to the production of scions, due to increased quality and uniformity of seedlings, we conducted an experiment testing the performance of seeds and the development of seedlings from different positions within pods. Seeds collected from the basal and stylar ends showed better germination and vigour. There was no influence of position on the length of shoots, total biomass of seedlings or the partition of biomass. However, seedlings from seeds of the stylar followed by those from the basal ends had relatively more leaf area. The results reported here are different from those reported for other legume species, where the seeds from the stylar, basal or middle of the pods have the best performance. This suggests significant but independent effects of high vigour pollens and/or hormonal effects in the formation of flamboyant tree seeds.
