The Effect Of Gibberellic Acid In The Growth Of Dw

The Effect of Gibberellic Acid in the Growth of Dwarf and meet Pea Seedlings Biology 167 March 24, 2012 Introduction: Gibberellic Acid is a natural occurring plant hormone that stimulates and regulates plant step-up. Known as GA3, this hormone promotes cell division and stem enlongation, resulting in a taller plant1. Gibberellin was first discovered in 1926 by a Japanese scientist; Eiichi Kurosawa. It was first isolated in 1935 by Teijiro Yabuta and Sumuki from fungal strains provided by Kurosawa. Yabuta named the isolate as Gibberellin. The Gibberellins are named GA1 through GAn in the come in it was first discovered. Gibberellic Acid which was the first Gibberellin to be structurally characterized is GA3. As of 2003, there were 126 GAs identified from plants, fungi, and bacteria. In this sample we demand try to conclude if Gibberellic Acid has an effect on the growth of a pea plant plant plant. We exit have both several(predicate) pea plants for this experiment. One is a nanus plant and the mated a normal pea plant. They will both be introduced to the same amount of Gibberellin Acid with three different concentrations.

At the end of seven (7) days we will observe and stop over the results of Gibberellin on the pea plants. The pea plant has been connected with otherwise important biological experiments, such as those of Gregor Mandel. It has been discovered that the pea plant that Mandel used in his experiments had GA3. The rook plants had a magnetic variation GA1, which caused growth in dwarfism. Dwarfism is a inheri table characteristic possessed by some peas.! It has been discovered that dwarf mutants cannot get normal quantities of GA as compared to normal cultivars. This experiment will test the hypothesis that dwarf pea plants are short because they do not produce as overmuch GA as normal plants.
