Lab Report On The 20 Wheat Seedlings

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.

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

All five groups recorded the outcomes that they established. For our bench, we found that nine raddish seeds in the control dish, zero raddish seeds in the eucalyptus dish, and four radish seeds in the lemon dish germinated and sprouted. Our bench also found that the average seed length for the control was thirty one millimeters, for the Eucalyptus was zero. and for the Lemon was eight and a half. Below, is a chart and graph that shows the whole data as averages from all five benches. Each bench did the exact same experiment so we knew nothing would be biased.

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.

Each quad of soil had 2-3 seeds in it along with either 0, 3, 6, or 9 pellets of fertilizer in each quad to possibly get 4 plants total. Two types of fertilizer exist, organic fertilizer and synthetic fertilizer. Gardeners.com says that, organic fertilizers are made from organic materials. (1) Organic fertilizers also prevent the plant with a better structure, improving the structure of the plant. (2) Synthetic fertilizers are fast-acting fertilizers but also come in different forms such as granule, spike and pellet. (2) This kind of fertilizer is also known for seeing green in the plants quicker and quick-hit of nutrients for the plants. (2) There are advantages and disadvantages of using fertilizer. Plants can have a quick action of growth and are more defined when using fertilizer. (3) But sometimes there is a chance of using the fertilizer to much causing damage to the whole soil ecosystem. (3) Over two weeks we observed the growth of the fast plants and recorded the data of the height. By the end of the two weeks, we also recorded the weight of the fast plants. I hypothesized that each quadrant was going to be different plant growth, with the quadrant of 6 pellets (quadrant C) being the fastest growing plant. My individual results showed that the quadrant with 9 pellets (quadrant D) had the most results with growing in

The estimated sample to be taken should be 9 lettuce plants/ roots to have the 95% level of confidence and within the 10% of population mean.

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

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)

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

The plant material used in this experiment were marigolds. Planting the marigolds into six-pack cell containers, making the total plants used 54. Using three cell packs for every treatment mixture with third treatment being the controlled treatment, meaning that no material is added or taken from the solution. Treatment one was a mixture of miracle grow and perlite, what is perlite? Perlite is a lightweight particle that can hold up to four times its weight in water. The second treatment was a mixture of miracle grow with sand, leaving treatment three to be the controlled treatment which was just miracle grow.

We hypothesized that at Miracle-Gro concentration 1, this solution will be the most effective towards the rate of growth because at pure solution, the concentration is so high that the effect will occur sooner than those of lower concentrations, and speed up the life span to expiry of all the plants in the single solution concentration. Because we accept as true, that pure concentration will have the highest rate of growth, we can eliminate this concentration from our second question. We have come up with the presumption that at the concentration of 0.1 solution will allow the plants to be the most successful for the longest period because concentrations less than 0.1 would not appear to have any effect. There would be limiting nutrients within the solution and therefore would have a yield due to the lack of Miracle-Gro

Repeat steps 1-5 with 5% concentration of sodium chloride (use mass balance to find 5%)

The six plots were individually given a treatment. Two of the plates were treated with 3.0 mL of Gibberellic Acid (GB). We chose to treat two of them with the same amount to see if our overall outcome was about the same. The second two plates were treated with 1.5 mL of Gibberellic Acid and 1.5 mL of deionized water (DI). Again, we treated two with the same amount to validate our results. The third two plates were treated with 3.0 mL of DI water; this was our control plate which did not receive any of the hormone. These treatment amounts were chosen by wanting to conduct an experiment having one treated with all hormone, half hormone and half DI water, and just DI water. We wanted to determine what effects the hormone had on the root length and stem length.

Our methods were fairly simple. To make sure our results were accurate, we used three plant pots to plant our seeds. We labeled the pots with our names and their cross numbers. Filling the pots with soil, we made sure it was damp and not wet by squeezing the soil out and packing it in the pot about half way. Then, we planted five seeds and spread them out, so they had room to grow. Lastly, we covered the seeds with more soil, also packing it lightly but tightly. After the plants grew, we examined and determined that our hypothesized ratio was 3:1 with a sample size of 38. Our phenotypes were green and white. We used a Chi-square analysis to determine our hypothesis. Null hypothesis: There is no difference in phenotypes between corn plants. Our alternate hypothesis was that there is a difference in phenotypes between corn plants.

The experiment entailed the utilization of three species of plants. The first species, Oryza sativa Linn., was preselected while the last two species were left to the discretion of the proponent of the study. Prudent seed selection was done to ensure the preservation of the diversity of the plant species that will be utilized for the experiment.
