Abstract: A system and a method for producing a quantified defined portions of powder from at least one biological material at cryotemperature is shown, comprising means for grinding the biological material deposited in at least one first vessel to the powder; means for loosening the powder resulting from grinding the biological material in the first vessel; means for positioning at least one first opening in the first vessel, and means for transferring the quantified defined portions of powder in a plurality of second vessels by using the first opening as a transfer way.

Abstract: A process for identifying whether plant is resistant to chilling comprises cultivating the plant at a reduced temperature for a time period selected from short term and medium term; harvesting a tissue sample of the plant; measuring concentration of at least one metabolite in the tissue sample of the plant; comparing the measured concentration with the concentration of the same metabolite in a tissue sample harvested from a reference plant or a plant of the same species after cultivation at a reference temperature; and optionally, repeating the process of foregoing steps but cultivating the plant at a reduced temperature for a time period selected from short term and medium term and not previously used; wherein resistance to chilling is indicated by one or more of the effects on metabolites listed in Table 2 or Table 4.
