The samples were sifted, and the seeds were separated and classified as full or void ; , using a gravity separator based on the seed weight, and those seeds containing an embryo were regarded as the heaviest and therefore as the ones with the highest germination potential.
Para ello, se utilizó un separador por gravedad, cuyo principio es el peso de las semillas, y se consideró aquellas que tienen embrión como las que pesaban más, y por tanto tienen mayor potencial de germinación.
