Abstract:
1. A method of testing seeds possibly bearing a seed-transmissible plant pathogen, comprising; a) placing a substratum for germination with seeds disposed uniformly thereon in a hermetic container; b) allowing the germination substratum with seeds to stand for a period of time necessary for the seed-transmissible plant pathogen to multiply sufficiently; c) periodically discharging air from the hermetic container while avoiding destruction of seedlings resulting from germination of the seeds; d) feeding fresh outside air into the hermetic container; e) after the period of standing, adding an extractant to the hermetic container; f) mixing up the seedlings, the germination substratum, and the extractant with stirring and/or pressing, to thereby obtain a mixed liquid; g) removing the mixed liquid from the hermetic container; and h) testing for seed-transmissible plant pathogens possibly occurring within said removed mixed liquid.
