Liquid Priming is ideally used to have a controlled imbibition and therefor pre-germination of seeds in an osmotic liquid, with the objective to have a higher germination and more uniform seedling performance.
Liquid density grading is very suitable for a high accurate separation of weight differences between seeds after an imbibition or priming process. In a specific density liquid, seeds with a lower density will float and seeds with a higher density will sink. In this separation method, viable seeds are separated from the less viable seeds, which increases the germination quality of a seed lot.
