Method for producing germination-treated plant seed, method for producing seed for germination induction, composition for extracting germination-treated plant seed, and screening method

摘要

[PROBLEMS] To produce a novel germinated plant seed suitable for production of a large amount of phytoalexin, a method for producing a seed for germination induction used in the production of such a germinated plant seed, and extraction of the germinated plant seed A composition and a screening method for candidate plant seeds used for production of a target substance are provided. A method for producing seeds for inducing germination is a pretreatment step in which plant seeds are continuously maintained for 5 hours or more under atmospheric conditions of carbon dioxide concentration of 400 ppm or more and / or oxygen concentration of 19 vol% or less. Have Alternatively, the method for producing the seeds for inducing germination is a pretreatment step, wherein the mass of the phytochemical in the plant seed after the pretreatment step is 2 with respect to the mass of the phytochemical of the plant seed before the pretreatment step. It has a pretreatment process for treating plant seeds so as to be twice or more. [Selection] Figure 1
