The objective of this study was to evaluate the physiological quality of
Pilosocereus gounellei seeds stored in different environments and types of packaging for six months. The experimental design was completely randomized, in split plots with four replications. The plots received two storage environments, cold chamber and natural environment, and three types of package, multi-layer paper bag, plastic bag and glass. The subplots received the storage periods 0, 2, 4 and 6 months. After each storage period, the seed moisture content, percentage of germination, germination speed index and mean time of germination were evaluated. The cold chamber was more suitable to store xique-xique seeds compared to the natural environment. In that environment, all the packages were effective to keep the physiological quality. In the natural environment, the seeds packed in plastic bags showed the highest percentage of germination
(87%), but the multi-layer paper bag was more stable for all variables, with 58% of germination, speed index of germination equals to 3.9 and mean time of germination of 7.9 days after six
months of storage. In the natural environment, multi-layer paper bags showed the best results to the conservation of xique-xique seed viability.
