The results of this experiment clearly show a neutral pH is a much better solution for seeds to germinate in. Therefore, the solution with a pH of 7 is preferable for seed growth and germination than any solution that is acidic. However, since the basic solutions have not been tested, the results that a neutral solution is the best for growth cannot be fully true. Another experiment with solutions that have a pH of more than 7 would need to be tested to get accurate results. The seeds watered with a neutral solution with a pH of 7 grew an abundant amount more than those watered with the diluted lemon juice with a pH of 3. After conducting this experiment, the results concluded that the regular tap water is an appropriate solution for seeds …show more content…
On day 2, the seeds didn’t show any growth improvements, but they did start to become softer in touch. As the days continued, the seeds treated with water started to grow sprouts and increase in size. On the other hand, the seeds treated with diluted lemon juice grew little sprouts and did not show much growth in size. Around Day 12 or so, the conclusion that seeds watered with acid rain did not grow as much really stood out. By looking at the regular watered seeds and how far they had come along, the acid rain seeds did not seem to have a chance. This time, it was obvious that the acid rain seeds were not as healthy as they should be. On Day 15, the seeds watered with water showed a tremendous growth and some of the bean seeds were starting to grow leaves on them. The other pea and corn seeds were also very long and dirty. Most of the corn seeds were bright red and dirty as well. Even though the acid rain seeds were not as long, they still grew a tiny amount and looked somewhat healthy. All of the stems were green for all types of seeds and grew more than expected of them. Therefore in this experiment, seeds need to be treated by a solution with a pH of 7 in order to prosper in
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
For my seed experiment I had decided to see what the effect of sprinkling salt on a radish seed would be. So for my control group I had set six (6) cherry radish seeds in between a damp paper towel and then closed it within a Ziploc bag. For my experimental I had set it up the exact same way as the control group but I would sprinkle salt on top of seeds before I zipped up the baggie. I sprinkled the salt on the experimental seeds and dampened the paper towel once every day. Each bag was stored in the light and at room temperature (~70° F.)
The purpose of this experiment is to observe the effects of Sodium Chloride (NaCl) on the germination rate of Wisconsin Fast Plants.
Firstly, for the setup of the experiment, two styrofoam cups were filled with two inches worth of standard, fertilized garden soil, next four seeds from from the garden seed, and the bird seed were placed an inch deep in separate cups. The seeds were blindly labeled, with one being labeled group A and one being labeled group B. This was so as to efficiently conduct a double blind experiment. The seeds were watered with approximately a teaspoon of water per day, and kept in a sunny windowsill. They were left in the windowsill for two weeks, and watered daily.
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.
In generalization, there are a multitude of factors that could potentially influence the germination of a radish seed. This lab thoroughly exhibits the effect of water amounts on the germination of a radish seed. There is indeed an in-depth science behind the projected results, and overall of the effects water has on the germination of radish seeds, and the growth of plants in particular. Radishes themselves are moisture-loving plants; therefore, it is significant that they receive an adequate amount of water, allowing the soil to be moist, but not overly saturated (Biology Coach, 2015). In general, water is significant for the health of a plant in the way it transports important nutrients throughout the plant. From this point, nutrients are drawn from the soil and used by the plant. Seed germination itself is defined as the process where the seed sprout for growing, and future development into a plant. In order to germinate, the seed must have its essential needs met until it is capable of doing so: water, temperature, and sun. Therefore, during its early stages of growth, the seed will rely upon the food supplies stores within it, until it is large enough for its own leaves to begin making food through photosynthesis (Biology of Plants, 2016). Initially, the process of germination begins with the absorption of water y there seed, therefore, this absorption of water then activates an enzyme that increases
A1.Work under the hood! With a pair of tongs, hold a strip of magnesium in a bunsen burner flame. Do not look directly at the flame. Save the ash in a small beaker for the next procedure. If magnesium is substance "A" in the general equation, what is "B"?
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)
Take the bowl of water and the paper towels. Submerge your hand in the water, then pat the paper towel with your hand, to dampen the towels before planting but not to the point where the towels are soaked. Do this for each group of seeds soaked in the solutions (5).
The second step of the experiment was to soak the seeds in water overnight. This action was made to prepare the seeds for germination and making them more softer and less rigid. The seeds were placed in a bowl and were covered by tin foil. It was set up on the refrigerator to minimize any outside interference that may come to it. After a full night of absorbing the water, the seeds were ready to start the next stage.
A black sharpie was used to label the bag “3.1” which stands for test subject three (3), part one (1). The second bag was then labeled “3.2” which stands for test subject three (3), part two (2).This was then written on the outside of the bag. One (1) tablespoon of springfield tap water was measured and poured into a small, 4 ounce, plastic, rubbermaid tub. One (1) micro essential laboratory pH strip was taken and dipped half into mixture. The pH stip was dipped into the substance for one (1) second. After the pH strip was removed it was placed against the container the pH strips came in which contains a chart. This chart matches the color of pH strips to a certain acid or base value. Once the pH was lined up the pH value was measured and recorded, the mixture was taken and poured directly onto the towel. The bag was then zipped up while applying slight pressure to the bag, without touching the seeds, to let out most excess air. Finally the bags were carried with caution to the desired location that is exposed to 11 hours of sunlight including 5 direct sunlight hours. These steps were repeated once
This experiment was focused on the effect that salt water has on bean plants, as opposed to tapwater. Specifically, does watering a plant with saltwater, instead of tap water make plants grow healthier or faster? It was hypothesised that if a plant is watered with only salt water, then the plant will not grow as well as one watered with tap water. During this experiment, The quantitative data that was collected included the plant height and the amount of salt that accumulated on the surface of the soil. The qualitative data was the color of the plants, soil, salt clumps, and the appearance of the plants overall.
Developing the radish seeds was a fun experiment. When I was studying the celery in the glasses, the container that had practically no salt appears to demonstrate that water went up from the base into the clears out. At the point when salt was included, the procedure was much slower. In view of the unequal dispersion, salt pushed water out of the celery instead of into it. I believe that the celery was attempting to dodge root harm from the salt so it pushed down as opposed to up. Salt appeared to have negative impacts in both parts of this analysis as it likewise appeared to moderate the rate of germination in radishes. The more salt present, the slower the procedure of germination could be completed.
This lab was a success, because it shows what happens with acid rain, and its effect on seed germination. The seeds will actually grow
Low germination rates reduce crop density, which results in indirect yield loss. Late emergence can result in poor plant performance and a direct yield loss [4], because roots are inadequately established and have less access to water and nutrients during later stages of vegetative and reproductive growth. Our knowledge of the regulation of seed germination has developed greatly in recent times, yet understanding of the genetic and mechanical basis for seed vigour differences is limited. By enhancing the seedling vigour trait, the agricultural industry might attain a remarkable advancement and increment in plant development. Seed vigour contributes directly to the economic success of commercial crops (Finch-Savage, 1995) and seed companies therefore need to have the means to obtain a reliable estimate of seed vigour in order to be able to supply growers with seed lots of high vigour.This will increase the margin of profit by reducing cost of production and increasing productivity. Thus, seed vigour, if enhanced, will result in substantial savings. Keeping in view the above information, this paper will be beneficial in determining the genetic and mechanical basis of seed vigour.
