Brassica Rapa

all treatments contain the same type of soil, are planted in the same size of pan, are exposed to the same amount of sunlight, and are maintained at the same temperature throughout the course of the experiment. ON THE TEST there will be a number of related questions about this section not just the question shown below.

There were two types of plants used. Both were of the same species, Brassica rapa but two of the plants contained rosette shaped complexes that were deficient in producing gibberellic acid compared to the wild-type plants. Therefore, they grew smaller and shorter as a phenotype. The Brassicaceae family includes cabbage, cauliflower, spinach, and many others. (

Wisconsin Fast Plants (WFPs), or Brassica rapa, are plants in the Cruciferous family, developed through selective breeding from a strain of Himalayan weeds (Williams). WFPs have a life cycle of around forty days. This short life cycle makes WFPs valuable for laboratory study. In addition, WFPs are simple to grow, as they only need water and a light source to survive (Williams). Their simple needs, allowing ease in controlling variables, make WFPs ideal for use in experiments.

The Wisconsin fast plant also known as the Brassica rapa belongs to the crucifer family of plants, closely related to cabbages, turnips, broccoli and other vegetables. Brassica rapa plants are used because they are viewed as model organism, a species that has been widely studied and can be breed in a laboratory. It is an ideal model organism because it has a short growing process. About 2 weeks after the plant is planted it will began flowering, possessing the ability to produce seeds at high planting density, is categorized as a petite plant size, and lastly has the ability to grow under continuous fluorescent lighting in a standard potting mix. This plants make it easy to track the genetic information passed from generation to generation

At the start of this experiment we were required to obtain a set of four Wisconsin Fast Plants, which are genetically, known as Brassica rapa. These plants have been, “originally selected under continuous fluorescent light to grow and reproduce quickly for research purposes, these petite, fast-growing plants have been used for teaching biology concepts” (Wisconsin Fast Plants). These four pots that contain our plants will be under our watch for the next 16 weeks where we will show our results at the end of the semester.

Throughout this experiment, we are researching the effect on the growth and survival of Wisconsin Fast Plants using fertilizer pellets to help with the growth of the plants. Wisconsin Fast Plants is a plant member of the crucifer family which is related to other plants (vegetables) such as cabbage, broccoli, turnips, etc. This plants are small and can grow very easily because they go through their cell cycle around 40 days. Wisconsin Fast Plants Fertilizers are different materials used that can provide plants with the nutrients it need to grow. (1) These plants are a good model system to study because they grew very quickly and didn’t need a lot of resources to grow making them the perfect plant to use for studies. (4) By using the fertilizers,

The low-density radish-collard mix pots contained four seeds of radishes and four seeds of collards. The high-density radish-collard pots contained 32 seeds of each species. While our group replicated this 3x2 design four times to total 24 posts, we incorporated the whole class data. Therefore, there were 16 replicates for each treatment. For each pot, we filled soil up until about one inch from the top. We placed the seeds in the pot and piled on around 2 or 3 cm of soil on top. In 3 species levels, seeds were spaced as evenly as possible. In the mixed species pot, the two species were alternated so that each one had the same access to space and nutrients at the other. For each pot, we wrote down our section number, group name, and the contents of the pot. Our group worked at the first bench in the greenhouse and also contained our pots that were spread out evenly in four rows. Our pots stayed in the greenhouse for about five weeks, captured as much sunlight as they could, and got their water source from sprinklers that automatically came on twice a

In order to test this hypothesis and prediction, an experiment was conducted using a heterozygous F1 generation of Brassica Rapa seeds. The seeds were planted, pollinated, harvested (F2 generation) and germinated for observation. When leaves were visible, phenotypes (green vs. purple) were counted and recorded. The experiment took place over 13 weeks, spanning the full semester of General Biology Lab I. The sections that follow will detail the materials and methods used, the results of the investigation and an in-depth discussion of the outcomes.

While experimenting with the green beans, the seeds exposed to the organic plant food germinated within five days of the experiment and the seeds exposed to the chemical plant food germinated within six. The seeds that acted as the control had been expected to grow the least, however, it was surprising that they did not grow at all. Both the chemical and organic fertilizers proved to have positive results on the plants. It was also unexpected when the seeds exposed to the chemical plant food surpassed the height of the other experimental seeds after being shorter. The predicted reason for the increase in growth with seeds given Miracle Grow was because chemical fertilizers automatically store up the nutrients and disperse it constantly throughout

From both graphs, the plant with two pellets and six pellets of fertilizer grow faster than zero fertilizer and four fertilizers. Compare to the plant with two pellets and six pellets, the six pellets one grow faster than the plant with two pellets. The plant with four pellets grow slower than the plant with no fertilizer. However, the data doesn’t make sense, so it is unreliable. Also, it does not support the hypothesis. The reason why the data is wrong, is maybe because the Brassica rapa was extract in the first week for measuring the length. Neverthless, it was a wrong action.Therefore,

The control group is the soil from the backyard while the experimental groups are the potting soil and Haw River soil. One cup of soil and five mL of Pennington Tall Fescue grass seed will be placed in each container. Three cups of waters will be given to the grass every other day and the height of the grass will be measured every week. At the end of the experiment, potting soil with 21% nitrogen had the highest grass grown. The backyard soil was the second highest grass grown with 17% nitrogen and Haw River had the shortest grass with 13% nitrogen.

There is a drought in California which is in turn affecting the number of crops that can be grown in a given amount of time. Farmers now must find a way to grow crops in an economical fashion while also maximizing each yield as much as possible. However, plant growth can be influenced by seed variety, the amount of water, the soil type, amount of light, etc., and many other variables. For this experiment, we are testing the growth of the Brassica rapa, a mustard plant under the same conditions of water, sunlight, and oxygen, with two different treatment solutions. There will be two pots, one has a treatment of just deionized water and the other a treatment of fertilizer as well as deionized water. Because the fertilizer has the added benefit of nitrogen, phosphorous, and potassium along with the same quantity of deionized water as the first pot, it is hypothesized that both sets of plants will grow, however the pot with fertilizer will grow more than the pot with just water treatment.

This experiment studies the effect of the hormone, Gibberellic acid, on the growth of plants. The hormone increases cell growth and cell division in the stems and leaves of plants. Gibberellic acid is applied on food crops to quicken germination because it is naturally occurring and has a low toxicity (Phillips, n.d.). The purpose for studying Gibberellic acid is to observe how it affects the growth of plants. The Brassica rapa and the rosette receiving the hormone Gibberellic acid will show an increase in their health, wet mass in grams, and dry mass in grams than those that do not receive it.

Cabbage may be considered a foliaceous inexperienced or crimson biennial herb, mature as associate level total annual veg crop because of its dense-leaved heads. Cabbage is powerful. Ancient healers declared it contained moon power as a result of it grew within the moonlight.

The first factor that I will be testing will be temperature. Different samples will be taken and grown under
