Although this method is accurate, it takes 8 days.

3. Red ink staining. A commercially available red ink plus 19 copies of tap water was used as a dyeing agent; 100 corn seeds were randomly selected and soaked in water for two hours to allow them to swell; and the emulsified embryos and milk embryos were peeled off with tweezers; After the treatment, the seeds were uniformly placed in the incubator, and the dye was injected to submerge the seeds. After dyeing for 15 to 20 minutes, the dye was poured out, and the seeds were washed repeatedly with tap water. Dead embryos and endosperm appear dark red, and live embryos are not stained or slightly light red. Judging the number of live seeds, this is divided by 100 and multiplied by 100% for the germination rate.
