Fast Plants Lab Report

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.

This experiment was performed to give a better idea of interspecific competition and intraspecific competition between radish seeds and wheat seeds at high and low densities. By planting two species only pots and two combined species pots our results showed that the radish seeds performed better at both interspecific and intraspecific competitions and concluded that the lower the pot density the more resources and growth. 32 radish seeds were evenly planted in pot A1 followed by 32 wheat seeds planted in pot A2 and 16 of each radish and wheat seeds combined (32 total) planted in pot AB1. We repeated this procedure again but this time planting 96 radish seeds evenly in pot A2, 96 wheat seeds in pot B2 and 48 of each radish and wheat seeds combined (96

The objective of Day 1 of this lab was to create a liquid fertilizer with 10% phosphorous by mass, 80% nitrogen by mass, and 50% potassium by mass using soluble compounds containing those elements. Additionally, a goal of Day 1 was to attempt to keep the pH of the final fertilizer within 6 and 7, although if the pH was outside this range it was not necessary to adjust the pH of the fertilizer to fit within this range.

Fast plants were first routinely planted in Nepal by a farmer. Generations later, a plant explorer recognized them as brassica plants. She took seeds back to the United States and they were left untouched until a scientist was looking for a brassica plant in order to further study diseases that plagued plants of the same family, such as cabbage or broccoli. This scientist decided to use these Fast Plants because they had a much shorter life cycle than the other plant he was considering using (Williams). Instead of a year per each generation, fast plant’s life cycle is only thirty-five days long, as is seen from the image to the left. The plants usually are flowering in twelve to fourteen days (Wisconsin 1). A typical life cycle of fast plants is faster than other plants, contributing to its name “Fast Plants”. Typically, the cotyledon will appear within forty-eight to seventy-two hours, true leaves should form in four to nine days, and flowers will open in thirteen to seventeen days. By using Fast Plants, data is able to be collected quicker than if a traditional plant was to be used. However, in order to optimize growing time, certain conditions need to be met.

According to a study, an experiment was done over the course of six years on the growth, needle, carbon, and nitrogen, chlorophyll, and

On the first day, four Styrofoam cups were obtained, and with the use of a pencil, holes were punched in the bottom of each of the cups in order to provide the plants with water. Cups were labelled in sequence: rosette-water, rosette-gibberellic acid, wild-type-water, and wild-type-gibberellic acid. Each cup then received approximately one inch of moistened soil. Following the addition of soil, 3 pellets of fertilizers were placed in each of the cups. Then, an additional inch of soil was placed over the pellets in each of the cups. Once the soil was settled, seeds were added to the cups. There were two types of seeds: rosette Brassica rapa seeds and wild-type Brassica rapa seeds.

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,

Nitrogen helps plants with growth and seed/fruit production. Nitrogen is apart of chlorophyll, which is responsible for photosynthesis. So as shown in this experiment, the same amount of sunlight and the amount of nitrogen that is given affects the plant’s growth. If nitrogen levels decrease, the height of the plant also

Table 1 shows the results of our measurements for each of the three weeks. As seen in the table, the shortest plant measured for the control grew a total of 7.5 cm over the course of seven weeks. Meanwhile, the shortest plant measured for the SUPERthrive grew a total of 6.85 cm. The tallest plant measured for the control group grew 10.5 cm, while the tallest plant measured for the SUPERthrive group grew 8.5 cm. Figure 1 shows each of the heights for all three weeks. There is little change between each group. Figure 2 shows the average change in height for each group. The SUPERthrive group had an average of 4.5 cm change in growth while the control group had an average change of 3.83 cm over the seven weeks. Figure 2 was taken

Graph 1 in appendix A shows the plants took a couple of days (7-10) to grow because they had to germinate. But on day 7, the water plant was 1mm and grew to be 2 inches. The Detergent plant grew to 1mm, and the Dish soap plant grew to 2mm. The data does support the hypothesis.

The reason we conducted the experiment was to learn how much fertilizer to use on lawn grass, and how it affects grass. We found in the research that fertilizer helps the plant grow (with the right amount) in long amounts of time. Our hypothesis was if we change the amount of fertilizer in the grass plants soil than the amount with 1 tsp. will be the tallest and healthiest, because it will not be too much or too little but just right. To create this experiment we filled cups with soil and poked holes for the grass seeds. Then we watered the seeds and added the amount of fertilizer needed to each cup. An answer to our question is that fertilizer does affect plant growth with the right amount of time needed. In our experiment the plants without

My hypothesis where wrong, I assumed that the outside bag would have germinated with the best results being in direct sunlight and outside air. I believe that the low temperature outside had a big part in playing with my results, maybe if the experiment was done during the summer months I would have had different results.

Since many of the plants followed this pattern, the trend between their mount and growth will be calculated using negative numbers for the plants that went down in weight. The plants that were grown in wood’s average growth in weight was -0.363 grams and their growth in leaf length was -0.05 centimeters. For the plants grown in stones, the average growth in weight was approximately -0.327 grams while the average growth in leaf length was 0 centimeters. Lastly, the average weight growth for the control group in a plant hanger was -0.202 grams and their leaf growth was 0 centimeters. Plants 3 (grown in wood) and 4 (grown in stones) exhibited the largest decrease in weight, losing 0.633 and .607 grams from the first to 36th day. The plants with the least decrease in weight were plants 5 (grown in stones) and 7 (control group), with a loss of 0.145 grams and 0.139 centimeters, respectively. Only three plants increased in their leaf length; plants 1 (grown in wood), 6 (grown in stones), and 7 (control group). Both plants 1 and 6 increases in height by 0.1 centimeters, while plant 7 increased by 0.2

Organic sources of nitrogen have shown to assist the development of many different plants, such as spore germination. An experiment was conducted to see if ammonium nitrate would indeed help with spore germination pertaining to the C-Fern, Ceratopteris richardii. The experiment consisted of two different dishes, each containing a different culture- one with ammonium nitrate and the other without. It was hypothesized that the control group, the petri dish without the ammonium nitrate, will have a higher rate of germinated spores compared to the experimental group, the petri dish with ammonium nitrate. The results revealed that although in each group the control had more geminated spores that there was no significant difference or variance.

Prior to sowing the trial area was fertilised on the 14th of May with the product, Nitrphoska Perfect at 350kg/ha with a package consisting of: N(15):P(2.2):K(16.6):S(8.1):Mg(1.2):Ca(8)+Trace & Super Phosphate at 220kg/ha P(9.1): S(10.5): Ca(20). The total nutrients of the soil: N (53)*: P (27.7): K (58): S (31): Mg (4.2): Ca (50.3) + Trace had enough available nitrogen to feed the equivalent of a two tonne wheat crop yield. Lupins cultivars were planted at twelve inch spacing’s on the 11th of June. Trial design allowed for a buffer at either end of the plots to not affect the trial itself. For each of the three cultivars the treatments were randomised and were replicated to increase reliability of results (view figure 1). Each of the plot sizes were 1m in length and contained three windrows of each cultivar. Soil tests were taken from each individual cultivar in each plot on the 12th of August to test for nitrate levels. Lupins were then
