Corn seed vitality identification

the appearance of visual method. The shape and color of the corn seed embryo are observed with the naked eye. Where the embryo protrudes or wrinkles, dark and shiny, then the seeds are fresh, strong life force, can be used for production.
seed germination method is used. First of all, 100 seeds soaked with water for about two hours to absorb swelling, placed on moist grass paper, covered with moist grass paper, placed in sufficient oxygen, room temperature 10-20 degrees C environment, so that the seeds fully germinate; Although accurate, this method of assay takes 8 days.
red ink dyeing method. With a commercially available red ink plus 19 servings of tap water with dye, randomly extract 100 corn seeds and soak them with water for two hours to allow them to swell, peel out the swelling seed and emulsion with tweezers, place the processed seeds evenly in the
culture
, inject the dye, in order to submerge the seeds, dye the seeds for 15-20 minutes, and then pour out the seeds repeatedly, and rinse the seeds with tap water. Dead seed embryo, endosperm presents deep red, live embryo is not dyed or slightly light red, according to which the number of live seeds is judged, divided by 100, multiplied by 100%, is the germination rate.

red ink dyeing method. With a commercially available red ink plus 19 servings of tap water with dye, randomly select 100 corn seeds, soaked with water for two hours to let it swell, with tweezers to swell the seed, milk embryo one by one peeled out, the treatment of seeds evenly placed in the culturer, injected with dye, to flood the seed degree, dyeing 15-20 minutes later, pour out the dye, with tap water repeatedly rinse seeds. Dead seed embryo, endosperm presents deep red, live embryo is not dyed or slightly light red, according to which the number of live seeds is judged, divided by 100, multiplied by 100%, is the germination rate. 。
