Analysis Of The Brassica Rapa In Intraspecific And Interspecific Competition

Competition had a vast effect on  growth, especially on spartina patens.  Both plants flourished, growing the most in freshwater marshes, without the presence of neighbors.  However, with the presence of neighbors, spartina patens was overcome dropping significantly.  While typha angustifolia did drop with neighbors it remained stronger than spartina patens.  In the case of salt marshes, typha angustifolia did not grow at all.  While spartina patens was much more stable with or without neighbors in salt marshes.  This suggests that while typha angustifolia, more dominant in freshwater, unable to grow in salt marshes pushed out spartina patens, who was able to endure salt during growth.  In conclusion typha angustifolia was greatly subdued by abiotic factors, while spartina patens was more limited by

Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include, predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain plants adapt to these factors and thrive and others don’t do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These

might affect the fitness of each variant. In other words which factors might increase plant growth, survival,

A plant's growth ability is dependent on its ability to acquire the resources it needs to survive. Competition such as interspecific and intraspecific, limiting resources, and population density affect the fitness level of a plant. This experiment was conducted in order to test the capability of collards and radishes to grow in manipulated densities under interspecific and intraspecific competition. I hypothesized that both collard and radish plants will grow more efficiently in single species pots under low-density conditions. I also hypothesized that in the mixed species plots the radishes will be more fit to survive and grow better than the collard plants in both the high and low-density pots. Both high and low density and single and mixed species plots were planted and results were observed. There was a significant

For both interspecific and intraspecific competition the radish did its best however at the lowest density of 32. (Figure 1) These results did support our hypothesis that the lower the density the better the growth and the radish would thrive better at intraspecific competition however was refuted with us predicting that wheat would do better in interspecific competition. These results can possibly be explained by the idea of density-dependent growth meaning that as you increase population, resources such as light, soil, and water decrease and vice versa (Walsh and Walsh 2015). Also a possible explanation for our results is that the radish shoots were longer, taller, more in number versus the wheat shoots that were short, broad and few in number. The theory of allocating more roots if the there is less sun and bigger shots if there is less nutrient rich soil is shown in the experiment of intraspecific and interspecific competition of beans, in the end that beans that had more competition and the soil was poor had bigger leaves at the expense of its neighbors (Mania et al.

Today’s lab incorporated the six steps of the scientific method to the growth and development of their own Wisconsin Fast Plant, also referred to as “Brassica rapa” in the scientific community. My group’s experiment included researching the effect of acidity on seed germination. The Wisconsin Fast Plant or Brassica rapa, was originally created by Professor Paul H. Williams at the University of Wisconsin at Madison. The word Brassica can refer to many different plants such as mustard plants, cabbages, rapes, broccoli, brussel sprouts, cauliflower, kale, kohlrabi, turnip, rutabaga, and the Chinese cabbage. The Brassica rapa plants were created to help provide a better understanding and more research on the Brassica plant’s family diseases. Brassica rapa plants are in the Cruciferae family, and are named this way because all of the plants have 4 flowers in the form of a crucifix.

Would always result in the same type of plant, but higher chance of survival because it can reproduce by itself rather than having to have other plants around.

Spruce budworm (Choristoneura fumiferana (Clemens)) outbreaks have an important effect on succession of balsam fir (Abies balsamea (L.) Mill.) and spruce (Picea spp.) stands in eastern Canadian forests (MacLean 2004). Spruce budworm feeds repeatedly on annual shoots of balsam fir and spruce and leads to large-scale growth reduction and mortality (MacLean and Ostaff 1989). When overstory tree mortality occurs from defoliation, it creates gaps that allow understory plants to get an opportunity to release (Osawa 1994; Kemball et al. 2005). Defoliation also changes the competitive interactions between host fir-spruce and non-host species and may release the latter.

The relationship between the existence of gall on the goldenrod and the development on the plants by using aspect measurement at the Riverwood Conservatory Introduction This study shows that the present of the gall on the stems of goldenrod has a taller height of stems than the ones that without galls. The averaging about 4 feet (1.2m) in height, goldenrod is a perennial with clusters of bright yellow flowers. It has been used for centuries in the treatment of kidney stones, urinary tract infections, a variety of other medical condition. (1) Survival probability depends on gall size; in small galls the larvae is vulnerable to parasitoid ovipositor, whereas larvae in large galls are more frequently eaten by avian predators.

Germination of seeds, and early stages of growth are important determinants in interspecies competition (Mangla et al. 2011). Higher proportions of B. gracilis seedlings to B.rapa will allow B. gracilis to gain an advantage both in germination, and in development of its roots and shoots. B. gracilis can then establish itself and sequester resources (water, sunlight soil nutrients) for growth and survival before B. rapa. Additionally, it was predicted that the mean biomass (root and shoot) of B. gracilis would increase as the ratio of B. gracilis to B. rapa increased. Multiple roots of long length in B. gracilis will be favoured as they can better compete in water and nutrient acquisition against B. rapa (Craine and Dybzinski 2013). Increased ability to acquire nutrients thereby increases the availability of nutrients B. gracillis has to grow, increasing shoot length and thickness. On this basis, the mean height of B. gracilis was predicted to increase as the ratio of B. gracilis to B. rapa increased as

One of the most important Brassica rapa features is that many generations can be grown in a short period of time for experimental analysis and comparison(Tsunoda, 1980).Brassica rapaplants are involved in many research works recently in which they are crossed with other crops to modify their genetic fitness(Tompkins, 1990). The Chi-Square ( ) test was used in this experiment to determine whether the statistical data supports or rejects the hypothesis.

Analyses how these factors brought regnum and sacerdotium into direct and somewhat inevitable conflict and competition with one another.

The purpose of the paramecium experiment was to observe competition or allelopathy between two different species of paramecium in the laboratory. Allelopathy is a way organisms inhibit or affect other organisms when developing in nature. This insures the survival of one organism against another organism. For instance in plants, some can release a chemical that enters the environment and inhibits the growth and development of surrounding plants. Another example in nature is plants developing defenses to prevent herbivores from eating them. This kind of competition happens in nature when the need for resources is limited and survival is necessary. Competition is displayed throughout nature all the time. A man named Georgy Gause previously conducted this experiment between P. aurelia and P. caudatum. He determined that different factors influence how the two species compete and coexist. Ever since then not many scientist have attempted to experiment on paramecium. Only until recently have more experiments been attempted. The issue with the experiment was that it was conducted in 1935 and nowadays there are more advance ways to conduct and interpret the experiment and results.
