Vedclass · Answer

(B) The Avena curvature test is a classic bioassay used to detect and measure the activity of auxins,specifically Indole$-3-$acetic acid $(IAA)$.This test was developed by Frits Went in $1928$.In this experiment,agar blocks containing the substance to be tested are placed asymmetrically on the cut coleoptile tips of Avena sativa (oat) seedlings.The auxin diffuses into the coleoptile,causing differential growth (curvature) on the side where the block is placed.The degree of curvature is directly proportional to the concentration of the auxin present in the agar block.

The Avena curvature test is used for the bioassay of which of the following?
