The adequate storage will reflect directly on the physical, physiological and sanitary quality of the forest seeds and consequently on the process of seedling production. In this sense, the determination of suitable conditions for the storage of the seeds using packages and environments accessible to the producer are essential. Therefore, the objective of this work was to evaluate different packages (glass, plastic bag and kraft paper) and environments (refrigerator, freezer and laboratory environment) for storing seeds of Tabebuia chrysotricha (Mart. Ex DC.) Standl. (ipe). The variables germination, normal seedlings, abnormal seedlings and dead seeds were evaluated every 30 days for six months. The storage of yellow ipê seeds can be carried out in a plastic bag in the refrigerator (up to 150 days) and in the freezer (up to 180 days) with up to 70% germination.
