Influence of fungi incidence in germination on seeds of plantain (Plantago major L) in different periods of storage

Resumo

It was evaluated, percentages and germination speed, in seeds of Plantago major L., at different periods of storage. The seeds were placed in a sealed paper bag and then stored at room temperature for 30, 90, 240 and 570 days. The freshly collected seeds were exposed on a stand in shade conditions, for a period of 24 hours. After plating, seeds were exposed to a photoperiod of.of 12h light for 12 days until exteriorization and development of fungi. The experimental design was completely randomized. The analysis of health revealed the presence of four genera of fungi associated with seeds of plantain. Regarding the the germination speed index, the seeds stored for 30 days had higher rates than the fresh seeds. It was found that the seeds did not germinate after 30 days of storage. The high incidence of the Alternaria and Drechslera fungi did not interfere in seed germination of the specie.
