PROCÉDÉ DE FABRICATION D'UNE SEMENCE VÉGÉTALE TRAITÉE POUR LA GERMINATION, PROCÉDÉ DE FABRICATION D'UNE SEMENCE BRUTE POUR L'INDUCTION DE LA GERMINATION, COMPOSITION D'EXTRAIT DE SEMENCE VÉGÉTALE TRAITÉE POUR LA GERMINATION, ET PROCÉDÉ DE CRIBLAGE
The present invention provides a novel method of manufacturing germinated plant seeds suitable for producing a large amount of phytoalexin, a method of manufacturing raw material seeds for germination induction for use in manufacture of the above germinated plant seeds, an extract composition of the germinated plant seeds and a screening method for a plant seed candidate for use in producing a target substance. The method of manufacturing raw material seeds for germination induction comprises a pre-treatment step of maintaining plant seeds under atmosphere conditions of a carbon dioxide concentration of 400 ppm or more and/or an oxygen concentration of 19 vol% or less continuously for 5 hours or more. Alternatively, the method of manufacturing raw material seeds for germination induction comprises a pre-treatment step of treating plant seeds so that the mass of a phytochemical in the plant seeds after the pre-treatment step is 2 times or more relative to the mass of the phytochemical in the plant seeds before the pre-treatment step.
