 According to preliminary studies, the seeds quickly lose viability and therefore should be sown as fresh as possible.When this is not possible, it is recommended to keep them for a short period of time with the red sarcotesta within a wet substrate (sawdust and sand, for example), airtight container and at low temperature (about 4 °C).The fresh seeds do not need a pre-germination treatment; nevertheless, it is advisable to pay attention to the luminous conditions because this is a factor that affects the final results.
