The Affection Of Auxin Applied To One Side And All Location On The Stem

1775 words - 7 pages

Introduction:A natural response for a plant receiving sunlight on one side of the stem will trigger a response that will release Auxin to the darker side of the plant. Auxin will promote cell elongation on the dark side of the plant causing the plant to bend towards the light. It is because of phototropism. Darwin grew grass seedling where the light all around it. Then the result was the coleoptiles elongated straight. And the other experiment was that he grew grass seedling in the dark, and then the coleoptiles bent but not to die. It is because of phototropism. Plants will elongate in the dark in an attempt to reach light.Our experiment is basically to prove (hypothesis) the auxin affects the stem elongation not only in the light, but also in the dark. And if we apply auxin to one side or all around the stem, we will have different results. We predicted that if we apply auxin to one side of the stem, the plants will bend away to this side. If we apply auxin to all sides, the plants will grow straight. We predicted the plants applied the paste to one side of the stem and all around the stem would grow straight.Materials:Fast Plants seeds, Auxin, Paste without auxin, Water, Duct tape, Soil, Quads, FertilizerMethods:1. Added a wick to each quad to draw water from the source into the soil2. Added soil until each quad is about half full.3. Added 2~3 fertilizers pellets to each quad4. Added more soil and press to make a depression.5. Added 2~3 fast plants seeds to each quad and cover them with soil.6. Carefully water each section using a pipette until water soaks through the soil and drips from the wick.7. Place the quad on a watering tray under fluorescent light in the greenhouse.8. 12 days after applied the treatment as table below:1st group 2nd group 3rd group 4th group 5thgroup(control plants)Paste without auxin on one side of stem Paste without auxin all around the stem Auxin applied on one side of the stem Auxin applied to all location on the stem No treatment9.

Checked and measured the height and angle of each plant everyday.Result:★ First 12 days fast plants grew straight in the green house.★14 days later (2 days grown in dark) the plants have auxin applied to one side of the stem bend away to this side. The other plants were grown straight.★ 18 days after (6 days grown in dark) all of the plants grow taller. Leaves were yellowing and there were some flowers. The group has auxin applied to one side of the stem bend lower. The others groups grown straight. No treatment plants have slim stem and the other have thick stem.(Left hand side) Paste without auxin on one side of the stem Paste without auxin all around the stem Auxin applied on one side of the stem Auxin all around the stem No treatmentresults Grown...
