Seeds of wheat, paddy and maize showed positive correlation germination (%) and viability (%) as determined by________________?
Correct answer: D. Tz test
- A. Grow put test
- B. Ageing test
- C. Test of genetic purity of seeds
- D. Tz test
Explanation
The tetrazolium (TZ) test stains living embryos, so stain intensity provides a rapid estimate of seed viability that generally correlates with germination percentage. A grow-out test measures field or seedling performance rather than viability directly.
