Plant Growth Hormone Lab Report.

Introduction:

Plant hormones and product regulators are chemicals that affect flowering, aging, root growth, killing of leaves, onward motion of stem elongation, color enhancement of fruit, prevention of leafing, and many different conditions. Very small concentrations of these substances produce major growth changes. every marks produce hormones naturally, and growth regulators can be applied by people to are applied to plants by people. Plant growth regulators may be synthetic compounds that mimic naturally occurring plant hormones, or they may be natural hormones that were extracted from plant tissue. In our plant growth experiment growth stimulants and growth inhibitors were used. ideally the plants that received the growth stimulants should have grown larger than the others.

Methods & group A; Materials:

The 3 plants used in the experiment were corn, peas, and beans. B-Nine, IAA, Gibberlic Acid, and a have substance were the growth regulators used. Gibberellic acid stimulates cell division and elongation, breaks informant dormancy, and speeds germination. Indoleacetic acid (IAA) stimulates internodal elongation, rooting, and leaf abscission. B-nine reduces internodal elongation. The control substance is the independent inconstant in the experiment.

Four position pots, which were divided into three parts, were used for planting the seeds. Two seeds from each type of plant were put in the soil of one compartment of the four planting pots.



Each of the containers was labeled with the alike(p) hormone, and each division of each container was labeled for the alike(p) plant. The plants were then watered and stored. Next week the lengths of the plants were recorded, the hormones were put on the plants. One of the four types of hormones was added to each plant in its corresponding labeled container. The next week the plants were measured and lengths were recorded. The process of adding the hormones was iterate for four weeks in the...
