Brassica Rapa Essay

964 words - 4 pages

Introduction:
There are many defining characteristics of the family Brassicaceae (Cruciferae). Some characteristics are lobed leaves, non-reproductive parts consist of four sepals, four petals in a cruciform arrangement. The stamens are tetradynamous meaning they have four long stamens and two short (Distinguishing characteristics of plant families). The floral structure of the family Brassicaceae is very different from other families because they’re fruits.
Brassicaceae (Cruciferae) are economically important because they provide food for animals and humans, such as broccoli, cabbage, kale, cauliflower, radish, and turnips. The Brassicaceae family is important medicinally as well. ...view middle of the document...

In the reproductive development of plants, gibberellins can affect the transition from the immature to the mature stage, floral initiation, sex determination, and fruit initiation after pollination. Normal stem growth is controlled by gibberellin that is produced by the plant, not the applied (Taiz and Zeiger, 2010).

When the gibberellins are applied to gibberellin deficient plants such as rosettes promote intermodal elongation. The most dramatic stimulations are in the rosette and dwarf species. In addition to cell elongation, there is a decrease in stem thickness, a decrease in leaf size, and the leaves are usually a pale green color (Taiz and Zeiger, 2010). Rosettes are formed in short days and undergo elongation and flowering in long days. With the application of gibberellins, stem growth or bolting in plants is kept in short days (Reed and Howell, 1995). Short days mean that the plants will form flowers only when day length is less than 12 hours. Long days mean that plants will form flowers only when the day length exceeds 12 hours.
The purpose of this research project is to determine whether or not applying gibberellin with restore normal growth in rosettes. The research hypothesis is if gibberellin is applied to dwarf-like rosettes that lack gibberellin, then the applied gibberellin would allow for the restoration of normal growth in rosettes.

Methods:
Brassica rapa was grown according to standard procedures (Carolina Biological Supply, 2001). In each cubical there was one plant and one of them was transplanted. Osmocote, a fertilizer was used and had a mass of 0.12 grams per quad. The concentration of gibberellin used was 100 ppm and one drop was applied to each true leaf every other day. For the controls, a drop of water was applied to each true leaf every other day. The day the gibberellin was applied the height of each plant was measured with a ruler in millimeters. The height was taken from the start of the embryonic leaves to the apical meristem. The statistical test used was the Mann-Whitney Test.
Results:
Research hypothesis: If gibberellin is applied to dwarf- like rosettes...

The prediction was that the plants treated with GA would have a longer stem, than the plants that are treated with water.MethodsThe hypothesis was tested using two different types of Brassica Rapa plant. One type is a normal wild-type plant, other is a rosette mutant. The experiment was begun by filling up a four chambered container with a soil and adding a
