Question

The Avena curvature test for auxins was discovered by_______.

Answer 1

Avena curvature test:

1. Bioassay is a sensitive and specific test that determines the biological activity of hormones by measuring their effect on a specific part of plant material.
2. There are various bioassays to determine the concentration of auxin hormone in plants such as the Avena curvature test, split pea stem curvature test, and cress root inhibition test.
3. The Avena coleoptile test is a bioassay firstly done by F. W. Went. in 1928.
4. It is for IAA (indole-3-acetic acid).
5. It measures the angle of curvature of a decapitated coleoptile after placing an agar block containing auxin on one side.

Final answer: The Avena curvature test for auxins was discovered by F. W. Went.
