Question

Viability of the seed is tested with

• A. Triphenyl tetrazolium chloride
• B. Indole acetic acid
• C. Mercuric chloride
• D. 2, 4-D

Answer 1

The correct option is A Triphenyl tetrazolium chloride

After their maturation the seeds do not remain viable indefinitely. They have a particular life span during which they must germinate otherwise they lose their viability (or capacity to germinate) first gradually and finally completely. The Tetrazolium Chloride (TZ) test is often called the quick germination test. It's a chemical test used to determine seed viability, and results are usually available within 24 to 48 hours. So, the correct answer is ‘Triphenyl tetrazolium chloride’.
