Effect of Gamma Rays Radiation on Growth of Corn

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

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.

However, for each quad, the fertilizer used for the control was added altogether with the fertilizers being studied. Since the only plant that presented growth was in the control quad, it becomes necessary to explore the effects of excess fertilizers, and furthermore, excess nitrogen, would have in the development of the fast plants. Although Nitrogen is one of the elements most living organisms require, some studies have showed high levels of nitrogen can cause toxic stress to some plants, to the point where growth can be inhibited. (Yu et al.

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,

What water level did you select for plant growth during your first attempt? Describe the observations of your plants at this water level. Based on your data, was the level you picked the best choice for optimum

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

This lab was conducted to see what happens when black tea and water are used to enhance the growth of a radish plant. The hypothesis was that the plants that were given the black tea and water mixture were going to grow faster than the control plant (Devonte). The hypothesis was partially correct because all the plants grew substantially large closer to the end of the lab. Plant 2 (Bravo) started to wither away and die because it was over fed, and eventually drowned in water. The other two plants grew at a consistent pace and developed into healthy mature plants. To sum up, the lab that was conducted was successful in the sense that two out of the four plants grew rapidly without the use of enhancements or

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

The control group in this experiment is the group that is grown normally to test the effects of the rest of the experiment’s independent variables. Growing Brassica rapa plants in the control group will allow the other science experiments to be compared to the normal growth of a common Brassica rapa plant. The normal growth of these plants will be important in measuring the other plants to see how their sizes compare and to show how an untreated plant would grow. Because of the nature of the control group, there is no null hypothesis since all the plants should grow at the same rate. If the correct amount of sunlight and water are given to the Brassica rapa plant, then they should grow as a normal Brassica rapa plant would. The purpose of this

Also it helped to determine what is better to use,soil or cotton pad. Cotton pad is making the observation more clear so i can observe each day how the root length is changing in different Petri dishes. Also preliminary experiment helped me to find out what kind of concentration should i put in each dish to see the

Does the radiation affect plant growth. If radiation is placed on a seed it will grow faster. The first thing you do is find a seed you want to grow then get 3 seeds put one in the microwave for 15 sec then put another on in the microwave for 30 sec then the last one just keep it normally. Then have soil and a little container then plant the seeds. Then measure the plants growth and see which plant grew first. Check the temperature everyday while looking at the plants. Water the plants 10ml each give good sunlight. Make observations about your plants.The Independent variable was the amount of microwave radiation the seeds received .The dependent variable is the growth of the plants.The 3 controlled variables are the soil that was used ( Miracle grow potting

According to the Health Physics Society radiations have a positive effect on plant growth at lower radiation levels and harmful effects at high levels. Plants need some types of non-ionizing radiation like sun-light for photosynthesis. Though these solar radiations are vital for the survival of plants but some other forms of non-ionizing and ionizing radiations are deleterious for plants.

plants. This result indicated ~40% and ~20% reduction in root length of WT compared to

In the UK, Public Health England has calculated that on average people are exposed to about 2.7mSv of radiation per year; this radiation comes from number of sources ranging from ‘Bag of Brazil nuts’ (0.005mSv) to a ‘CT scan of the chest’ (6.6 mSv) (Sellafield, 2014). The maximum annual radiological dose that people are allowed to receive is 20mSv. To achieve below this, a day-to-day monitoring service of the plants condition should be carried out reporting results. A dosimeter (Thermo Luminescent Dosimeter)
