🔑 Key Points
Seed viability: It is the capacity of the seed to remain capable of germination for a specific period.
Potassium permanganate method:
→ This is a qualitative test used to determine the viability of seeds.

📝 Additional Information
Other Methods for Seed Viability Test:

Tetrazolium chloride test:
→ Known as a biological test.
→ Seeds are soaked in a 0.5-2% solution of 2,3,5-triphenyl tetrazolium chloride.
→ Viable seeds take a bright red coloration, and the color becomes more intense in the embryo.
→ This is the quickest method of viability testing.

Grodex test:
→ Grodex is a seed germination indicator.
→ It is a brand name for triphenyl tetrazolium bromide in powder form.
