The Effect of Radiation in Inducing Mutation on the Growth of Zea Mays

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 experiment was begun by obtaining four 8 oz. Styrofoam cups and punching a hole through the bottom of them. This hole was for water entry or excess water drainage. Moistened soil was packed to the 1/2 full line in the cup along with 3 fertilizer pellets The cups were labeled the following: Rosette-H20, Rosette-GA, Wild-Type-H2O, and Wild-type- GA.(Handout 1) A small wooden applicator stick was obtained a moistened at the tip with water from the petri dish labeled ‘water.’ This was to be able to attract the seed to the applicator in order to place the seed from its original container into

Introduction In this experiment, radish seeds were exposed to several different kinds of solutions (salt, soap, vinegar, fertilizer, distilled water) to test how different environmental pollutants affect seed germination. Because there are several kinds of solutions being tested in this experiment, there is more than one hypothesis. The hypotheses for this experiment are as follows: The use of fertilizer solution increases radish seed germination and growth. The use of salt solution decreases radish seed germination and growth.

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.

This study examined the effects of X-ray radiation on recombination frequency in Sordaria fimicola, a model organism. A Laboratory Manual for Biology 110 Biology: Basic Concepts and Biodiversity states that S. fimicola:

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.

Therefore, I was correct in my hypothesis that dark will have an effect on the germination of radish seeds. Also, I was very close in predicting that the seeds grown in the light will germinate twice as much as the seeds grown in the dark; the control seeds grew a little less than double the size of the experimental seeds. Ultimately, my experiment proved that light is a very important factor in the growth of any plant. However, I’ve learned that seeds grown in the dark will germinate, though slowly, as

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

No one particular organism is an exact replica of another. Diversity in the world is key for future generations to adapt to the fast changing world. This lab observed the corn plant of the Zea mays species to determine the genotype for the gene of tall versus dwarf in unknown parent corn plants by observing the seedlings produced. It was hypothesized that one parent is heterozygous while the other is homozygous recessive. The predicted results were that half of the seedlings would contain the tall gene and the other half would have the dwarf gene. Plants were grown for two weeks under

Before the final experiment, preliminary test was done to determine whether the recommended rate for the positive control (Nordox) and Farmer’s practice (Mancozeb) which is 25 g/16 L or 0.156% could inhibit or stop the growth of A. niger.

All seeds were exposed to the same amount of temperature and light as they were all kept in the same location at the same times

All of the plants involved in the experiment, Marigold, Squash, Radish, and Wisconsin Fast Plant, all were affected by the radiation from Cobalt, but some more than others. The plants all followed a similar trend, which was when the radiation amount would increase, the amount of growth would decrease. In the Marigold plant, the germination percentage for 0 KR started at 54.88%, but increased to 64.55% at 50 KR, before starting to drop it’s percentages lower as the KR amount went up. The squash plant had a continuous drop starting at 69.53% at 0 KR and dropping to 36.72% at 500 KR. The Radish plant started at 81.64% at 0 KR and dropped to 30.73% at 500 KR. The Wisconsin Fast Plant started at 85.16% at 0 KR and dropped a little bit to 64.71%

The purpose of this lab is to examine spore color to see evidence of crossing over in relation to x-ray radiation. The results from previous experiments show that x-rays might increase the frequency of crossing over in cells. X- ray radiation has been shown to damage to the inner structures of a cell and have enough energy to change atoms in tissues. The theories behind the effects of radiation suggest that the radiation may actually be effecting the genetic code of the cell (Rothkamm and Löbrich, 2002). Taking into consideration the possible effects of x-ray exposer, I hypothesize that the fungi exposed to the radiation will have a higher rate of recombination.

Fang & Yang, X., 2007). But (de Vendômois, Roullier, Cellier & Séralini, 2009) show the possible occurrences of toxicology in rats that was feed with three GMOs corn variety. He infer the necessity of studies by long duration to expatiate about cancer, fertility and mental problems in mammals.
