Plants growth rates can be altered using several factors. Anything from temperature, lighting, water, and nutrients can have an affect on any given plants development. Green plants cannot ingest complex molecules but can utilize elements like nitrogen, phosphorous, potassium, calcium, magnesium, and sulfur. Nitrogen is the main requirement for plant development and can profoundly affect plant development (Hershey, 1990). Interestingly, most household-potting soil is typically poor in nitrogen so soils may lack these components. Fertilizers are composed mainly of nitrogen, phosphorous, and potassium. These are considered the primary nutrients. Fertilizers may very well contain secondary nutrients also, mainly calcium, magnesium and sulfur (Hershey, 1990). These nutrients are absorbed through the roots using photosynthesis, water, and carbon dioxide through a process called transpiration.

Hormones can also affect the growth of a plant. Auxins, cytokinins and gibberellins are the principle hormones that affect plant growth. These hormones can either stimulate or inhibit the plants development. In general auxins promote root

The experiment requires three plastic tuber ware containers with lids along with three water mats and three algae stoppers. Three Styrofoam boxes with quads cells were needed with water wicks placed through the bottom. Potting soil was obtained as well as seeds of the Brassica Rapa wild variety and rosette variety. A permanent marker was used as well as a record sheet to record data and colored pencils and paper should be obtained to draw the plants stages. A one-milliliter pipet and gibberellic acid is required. Finally, eight fertilizer pellets were used, eight wooden stakes and a fluorescent grow lamp.

or the C/W were 7.7cm and 7.2cm. Results of the GA rosette measured a 5.3cm and 6.0cm which were higher than the wild GA which measured 5.4cm and 6.1cm (Table 3). The GA rosette (GA/R) in comparison to the control/rosette (C/R) showed an increase in height of nearly 5.4cm and 6.0cm to 0.0cm and 0.0cm respectively (Table 5).

It is also hypothesized that because of the plain potting soil used that the plants treated with fertilizer will develop larger leaves, flowers, seedpods, and stems. It is suspected that they will be healthy and bright green while the not treated control plants may look underdeveloped have smaller leaves and less flowering. It is also suspected that the plants with fertilizer will have a shorter germination time.

In this experiment, the addition of gibberellic acid and fertilizer in plant development will be assessed and evaluated in the B.rapa. Other environmental factors involved in a plants development will try to be controlled so that all the plants will be subjected to the same temperature, lighting, and water. The Brassica rapa is an excellent plant for experiments because of its rapid lifecycle. Because of this, the different factors placed on the plant can be assessed and monitored quickly. They are easy to use in a laboratory because of their relatively small size and generally forgiving environmental needs. There are two types of Brassica rapa used in this experiment, the Brassica rapa wild type and the Brassica rapa rosette type. The wild type Brassica has a gene that produces gibberellic acid while the rosette variety lacks this gene. This allows the wild variety to have stem elongation and height while the rosette variety has no stem elongation and is spread out on the gr!
