Experiment a. Relationship of Auxin with Apical Dominance Objective: Observing the relationship between auxin activity and apical bud dominance Materials and tools: Plant material : 3 plant potsColeus sp one variety per group Chemical material : vaseline, 400 ppm IAA vaseline Tools : Razor blade, 3 potted plants per group Ways of working : 1. Select 3 shootsColeus good sp. 2. Leave the first shoot alone, cut the second shoot and then apply Vaseline. The third shoot was cut and coated with IAA vaseline paste. The cut is made just below the shoot. 3. On the seventh day the vaseline and IAA vaseline paste were replaced with the same ones and the effects were observed. 4. Plants are allowed to grow in the laboratory until they are 28 days old after using IAA vaseline. 5. Measure the length of the growing side shoots and observe anything that appears to be affected by the treatment given. Experiment b. Auxin and Abscission of Plant Tissue or Organs Objective: Examining the role of auxin in the leaf abscission process Materials and Tools: Plant material : 3 plant potsColeus sp. Chemical material: IAA paste 400 ppm, vaseline paste Tools : label paper, millimeter paper, razor blade, spatula for give pasta Ways of working: 1. Select 2 pairs of leaves (four leaves) for each pot and cut them with a razor knife at the base of the leaves, and leave the petioles. 2. Apply vaseline paste to the ends of the 4 petioles of pot 1, and IAA paste to the ends of the 4 petioles of the second pot. The control was a cut without adding paste to the third pot. 3. Each petiol is labeled according to its treatment. 4. Measure petiole length when the experiment begins, and every 3 days for 21 days. 5. Note when the petiole falls. For this it is necessary to carry out daily observations.
