High Nitrogen Concentration Affect Pisum Sativum Growth?

In the dishes, I dropped the appropriate treatment into the center, where the marks were made. Next, I closed the petri dishes, taped them up, and let them sit at room temperature for a week. Then I opened them up to take two measurements. The first measurement was the number of seeds germinated. The second measurement was to measure the seedling lengths.

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

This project was to see the effect that caffeine would have on plants. This project was to figure out which amount of caffeine was to make the plant grow the most. The test subject plants that were used in this experiment was Basil. Basil is a plant that sprouts very quickly. It is supposed to sprout in around 10 days. The plant Basil has no caffeine in it to start with. The only plant that has sprouted was the control plant that had no caffeine in it’s soil at all. We used caffeine tablets instead of coffee grinds which are more natural because they are high on nitrogen. There was two with 400 mg of caffeine in them. Next there was two plants with 800 mg of caffeine in them. Lastly there was two plants with 1600 mg of caffeine in them. In

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.

Add three seeds to the potting mix and cover seeds with little remaining potting mix. After the addition of the potting mix, use a dropper filled with water and water each cell until water drips from the wick. Then place the quads on a watering tray under the fluorescent light bank. Each cell should have an equal distance from the light bank. Quads should be three inches below the fluorescent light; the light should also be left on all day. Make sure all wicks are in contact with the mat that sits on the watering tray. Also watch out for the watering system regularly throughout the experiment. After four to five days record plants in the quads, giving their phenotypes in a table for each cell removed all but the strongest plant.

At the start of this experiment we were required to obtain a set of four Wisconsin Fast Plants, which are genetically, known as Brassica rapa. These plants have been, “originally selected under continuous fluorescent light to grow and reproduce quickly for research purposes, these petite, fast-growing plants have been used for teaching biology concepts” (Wisconsin Fast Plants). These four pots that contain our plants will be under our watch for the next 16 weeks where we will show our results at the end of the semester.

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

METHODS/PROCEDURES: In the beginning of the experiment, pea seeds were used in order to perform the experiment. It was extremely important to acquire good, dry, and viable seeds so the process of germination could occur. A handful of these healthy seeds worked best in assisting the experiment. The seeds ability to germinate was a vital information needed to determine the outcome of the experiment.

Phosphate rock is mined from the earth. The rock is crushed and purified to form phosphoric acid, which may be reacted with caustic soda of lime to produce purified phosphate salts.

The independent variable was the type of seed used in the experiment, wheat and acacia. The dependent variable was the time that the seeds were placed into the water. The controlled variable was the temperature of the water which the two seeds were placed in. Whilst performing this experiment, a larger number of each seeds relating to each type of plant were used as some of the seeds may have been inactive, therefore, not germinating.

Plans can have two different kinds of growth: indeterminate and determinate. Plants that grow all throughout their lifetime and never reach a size limit have indeterminate growth. Most plant organs have determinate growth, which means that they stop growing after they reach a certain size. The reason that plants grow without ceasing is the presence of permanently dividing unspecialized tissues called meristems. There are two types of meristems: apical and lateral. Apical meristems are located at the tops of shoots and roots, and they enable primary growth, which is growth in length (Campbell et al., 2014). In primary growth, shoots grow upwards to try and absorb more light, and roots grow deeper into the soil to increase the surface area of the plant. Lateral meristems allow the plant to grow in thickness by a process called secondary growth. Herbaceous plants grow predominantly through primary growth, whereas woody plants use both primary and

Two will be the control with a normal period of vernalization at five weeks, two will be in a short vernalization period at three weeks, two will be at a relatively long period of vernalization at seven weeks, and two will be at the longest period of vernalization of nine weeks. The independent variable will be vernalization length, and the dependent variable will be the time it takes the plants to flower. The vernalization will occur at 4ºC. Otherwise; they will be grown at 23ºC. Before vernalization, they will grow at normal temperature for four weeks. Other constants include light, at 20-150 µmol/m2sec and humidity, at 55%. The plants will be grown in long day periods of fourteen hours of light, with dawn at 0600 hours and dusk at 2000 hours. For accurate results, the plants will be grown in a growth chamber. After their first vernalization, I will grow them at 23ºC for four weeks, then put them in a vernalization state again, but each for one less week than previously done. I will repeat this same process twice so that I can shorten the vernalization time again. Flowering time will be measured in days since initial planting to the first

5. Put plastic wrap over all pots until germination 6. Track growth every day for all 15 days. During this experiment all of the cat grass pots were measured every day for 15 days. I used a ruler to measure the growth of each plant. In the outcome of this experiment the regular water plant(s) grew the most, the one aspirin tablet plant(s) grew very little, and the 2 aspirin tablet plants didn’t grow hardly at all. I think this outcome happened because when I did research most of the experiments used very little amounts of medication in the plants. Also, the plants could have been over watered because the plants were watered with one and a half cup of water and aspirin added water every day. In my hypothesis, if aspirin water is added to growing cat grass, then the aspirin will make the cat grow faster because will speed up the growth process, this hypothesis does not support the data of this experiment. Since the regular water plants grew the most, that proves the hypothesis is incorrect. I think this experiment could be a benefit to society because if other students/teachers would ever want to do this experiment they can find out how aspirin does not help cat grass

.) For this experiment I will have three pairs of plants. All of these pairs will include one plant that doesn’t have any hormone added to it and the other that does. Every other day I will be adding a little bit of ABA to the plant soil. Each of these pairs will be put into different environments; one cold, one hot (or dehydrated), and one in normal conditions. This will let me know how the ABA affects stress. If it helps the plants deal with stressors, then the plant with the hormone added should do much better in the harsh conditions. Every two to three days I will be checking up on each of the plants to see how they are doing. I will do a measurement of the height of the plant, investigate the coloring of the plant, and the size of the
