Use Of Statistical Evidence From The Rye Seeds

There are many ways to obtain seeds to grow flowers in the springtime, but not all seeds were created equal. Sunflower seeds, for example, can be bought at a garden store in a packet for $1.5 dollars per 6 gram packet, but they can also be found in bird seed for $3.53 dollars per 10 pounds. This experiment intends to find if the germination of a store bought packet of sunflower seeds matches the germination rate of sunflower seeds obtained from a bag of bird seed. While both seeds will germinate, it is believed that the bird seed will not be as robust in growth as the garden seed, due to the fact that the garden seed is made to be grown, while the bird seed is made for consumption.

The hypothesis behind this experiment is that the Gibberellic acid has a positive growth effect on the plant and causes it grow larger in height.

The results observed do not correspond with the outcome predicted by the hypothesis. Despite the nature of the subjects of the experiments, no substantial growth was observed. Only one seed of the 36 planted germinated, and it could only survive for a period of a week. The one seed that germinated reach a height of 1.2 cm. Table 1 presents the average growth observed in each quad. Each quad had a total of 12 seeds. No seeds were removed during the course of the experiment.

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

In this experiment we are testing the effect of fertilizer on the speed of plant growth. We prepared a 4 quad cell, 1 control group and 3 experimental groups. So, we had one with no fertilizer, one with three seeds of fertilizer, one with six seeds of fertilizer, and lastly, one with nine seeds of fertilizer. The plants that we grew were called Wisconsin Fast Plants, members of the crucifer family. These plants are small and easy to grow, but for optimal growth they require continuous fertilizer, water, fluorescent light, and temperature between 18 degrees Celsius and 26 degrees Celsius 24 hours a day. Fertilizers are substances that are put into soils to increase the growth of the plant. There are two different types of fertilizers, synthetic

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,

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.

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

51) A botanist wanted to see if a new strain of corn could germinate in soil that was too salty for regular corn. She conducted a study on the germination success of seeds from the new strain that were exposed to various levels of salty soil, from zero to normal (100mg/L) to high (200 mg/L) to very high (400 mg/L) to normally lethal (800 mg/L)

The same ruler would also be used to measure all the plants the same way so that the measurement errors are reduced. The hypothesis is partly supported because slightly acidic plant did make the plant grow

In this experiment, beans were grown in various acidic solutions and compared to the growth of beans in water. Through the measuring of the beans length, the purpose of this experiment, which was to see how acid rain affected plants was achieved. According to the results, the data set shows high acidity levels decreases a plants growth rate. Compared to the control group the beans in vinegar were significantly shorter in the end of the experiment. Most of the seeds in vinegar solutions sprouted days later than the ones in the control group (water). Also, the seeds in vinegar ceased to sprout at all, due to the extreme acidity at a pH of three. The high acidity wore off the mottled coloring of the seeds. The data supports the hypothesis

Stichler and Livingston (1999) previously stated that a major advantage of winter wheat compared with other small grain species that could be grown for winter forage production is its excellent tolerance to abiotic stresses including cold and drought. In addition, wheat forage has relatively high nutritive values including high protein, energy values, minerals, and low fiber concentrations, compared with barley (Hordeum vulgare L.), oat (Avena sativa L.), and rye (Secale cereale L.) forages. Generally, forage yield of winter wheat from late November to early March is more consistent and productive than that of the other species (Denman and Arnold, 1970; Watson et al., 1993). Bockus et al. (2001) and Watson et al. (1993) mentioned that susceptibility of winter wheat to Hessian fly [Mayetiola destructor (Say)], leaf rust (incited by Puccinia triticina), and several virus diseases could be obstacles for successful winter forage production, especially in early planted regions.

Abstract Radioactivity is the process that an atomic nucleus loses energy by emitting radiation to form a more stable atom, and time for radioactive material decay to half of the isotope is defined Half-life. Radon-220 observed in the experiment theoretically has a half-life with 54.5s. Two methods derived from the definition of Half-life and Radioactive Decay Law used to demonstrate half-life of Radon-220 under 400V and the closest result from the whole experiment is 55.90s with 2.57% error. The relationship of remaining atoms of Radon (1/∆T) and total elapsed time (t) is the main idea to find out Half-life in the experiment.

Purpose: To see the effect of an acid introduced during seed germination, on the length of the plant roots. Also shows how salt can affect the seed germination. Acid can be introduced to seeds during germination if there is acid rain. Knowing the results of acid rain on seed germination will help us understand how to grow pants better, and how to have more successful germination. Salt can be introduced into a seed during germination because salt is put on roads and the salt builds up and can contaminate the soil. Knowing the effects of salt on seed germination will allow us to know for sure if the salt is affecting the plants growth or not.

Wisconsin fast plants were separated into two groups. A control group (n=12) and an experimental group (n=12). Both groups of plants were potted in black horticultural six packs (4 total). The type of soil used was a 1:1 ratio of humus to vermiculite. The fertilizer which was also used on both plants was Osmocote. The control group was watered with normal water through its uptake system, and the experimental group was also watered with the same tap water through its uptake system. However, the experimental group had 5mL of polluted water poured in each of the individual plant sections (12 total) after week 1. The polluted water was a mixture of 500mL of tap water and 1 gram of Seventh Generation natural powdered laundry detergent. The two groups were compared based on their stem height, number of leaves, and number of flowers. Using a ruler, the stem height was measured each week in centimeters from the base of the stem to the highest point of the stem. The number of leaves and flowers were also counted each week and recorded in the data table. The fourth week observations actually occurred five weeks after planting due to the fact that we were unable to record data during a week school closure. At the end of the experiment a t-test was performed to compare the means of the data.
