Bird Seed Lab Report

To perform this experiment we used two pots, wheat seeds, Centimeter measuring tape or ruler, labels(control and experimental) to identify different pots, water, misting bottle, compass used to know the specific direction, soil, wood sticks used for supporting the long leaves of wheat grass, and thread to fence the wheat grass.

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

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 experiment began by undergoing a hand washing with antibacterial soap for a minimum of 90 seconds and thoroughly drying them. Afterward, six (6) Bolder paper towels were taken and torn at the perforated line. An individual towel was then folded 3 times [See figure one (1)]; This step was repeated five (5) more times. Then sixty (60) pea seeds were counted out and separated into ten (10) equal groups. The pea seeds when observed had a shrivels like coat with a dull army green color. Next was to measure the length of the sixty (60) seeds and then calculate the average by adding up all the measurements then dividing the sum by sixty (60); this was recorded in a table provided [See figure two (2)]. Then the folded paper towel was taken and one group (10) of pea seeds

In this practical, six bags containing twelve histrix cactus seeds each were taken and another six bags containing twelve rocket salad seeds in each bag. Each bag was experimented with different concentrations of gibberellic acid to see how fast each would grow. Gibberellic Acid is an organic

A: Seed dormancy prevents the premature germination of seeds. A see will germinate only when the environmental conditions are optimal for the survival of its embryo as a young seedling.

A piece of filter paper was moistened and then placed in a petri dish, and any excess water was poured off. The harvested seeds were then placed in neat rows on the upper two-thirds of the filter paper. The petri dish was then tilted on end in a water reservoir containing approximately two centimeters of water. The reservoir and dish were then placed under the fluorescent light to germinate for 48 hours. After the 48 hours, the

Comparing the times evaluated in the ultrasonic bath (2 and 4 minutes), according to the statistical analysis there is no significant difference between the different times, because they present results very close to the percentage of germination of the seeds. Of the seeds that remained for 2 minutes in the ultrasound bath, 65% of them germinated, and of those that remained for 4 minutes in the ultrasound bath, 68% of them germinated. However, the statistical analysis showed that there is a significant difference between seeds that have undergone ultrasonic treatment and seeds that have not undergone any type of treatment, proving the need for a treatment to break dormancy of the seeds of this species, since of the seeds that have not undergone

Would putting plants at a higher elevation from the ground effect it’s growth speed? Would this actually work ? The experiment was conducted to find out how much plants would grow at different elevations. To conduct this experiment, you must first take a species of plant (sunflower). Once you have these, place one of each plant at different elevations. After this, you will just need to observe the plants for a week to see how much they grow. When all the steps are completed, you must measure the growth over the course of one week. This resulted in the sunflower at the higher elevation to grow 1.3 cm higher than it’s original height, 5 cm. On the lower elevation, the sunflower grew approximately 1.7 cm higher than it’s original height,

In a 2005 and 2007 study by L. Galloway, the maternal light environment of Campanulastrum americanum was shown to influence the offspring’s germination season by altering the maternal flowering time. C. americanum, also known as the American bellflower, is a native understory fern. Individuals can grow in either the forest understory or in light gaps, therefore, individuals will experience no direct sunlight, or full sunlight for some length of time, daily. Individuals within the C. americanum species are capable of having one of two life-history strategies. The relationship between maternal light environment and flowering time can influence the offspring’s life-history strategy by dictating whether the individuals grow as annuals or biennials. A majority of seeds in light gaps became annuals, germinating in the fall and flowering immediately the next summer, while a majority of the understory seeds grew as biennial individuals, germinating in the spring and growing for a season before flowering their second year. As the study results support, these flowering phenologies are two different life-history strategies that have been influenced by maternal effects. The study results have shown that twice as many seeds germinated in light gaps if their mother had grown within the gap, and that twice as many seeds germinated in the understory if their mother had also grown there. The population growth for individuals grown outside of their mother’s environment was determined to be

Seed was collected in December 1998 and 1999 from the wild population, and approximately 2700 seeds are now stored in the Department's Threatened Flora Seed Centre (TFSC) at -18�C. The 1999 collection was made immediately prior to the wildfire. The TFSC tests viability of the seed initially, after one year in storage and again after five years. The initial viability of these collections ranged from 84% to 97%. After one year in storage the germination rate ranged from 11% to 75% (unpublished data A.

The mean of the 30 seconds in 34° C water level was 74.4 cm per cup, while the control (0 seconds on 100W) had a mean of 80.3. This was interesting as, it was hypothezied that the heat would inhibit the growth significantly. The range within the level was surprisingly large, considering that there were ten seeds per cup.

Our methods were fairly simple. To make sure our results were accurate, we used three plant pots to plant our seeds. We labeled the pots with our names and their cross numbers. Filling the pots with soil, we made sure it was damp and not wet by squeezing the soil out and packing it in the pot about half way. Then, we planted five seeds and spread them out, so they had room to grow. Lastly, we covered the seeds with more soil, also packing it lightly but tightly. After the plants grew, we examined and determined that our hypothesized ratio was 3:1 with a sample size of 38. Our phenotypes were green and white. We used a Chi-square analysis to determine our hypothesis. Null hypothesis: There is no difference in phenotypes between corn plants. Our alternate hypothesis was that there is a difference in phenotypes between corn plants.

After completing this laboratory experiment the hypothesis that the salt water would affect the germination rate of the seeds was correct. The affect the salt water had on the seeds started at .5% at which the seeds began not to fully germinate. The percentages for germination began to fall passed the 100% germination rate that the 0% salt water had it also took only two days for full germination to occur. The .5% had a germination rate of 80% and took 3 days for the .5% to start to germinate and by the final day 8 seeds had full germinated. Then the 1.5 % had a germination rate of 60% and surprisingly germinated on the first day and by the final day had 6 of its ten seeds a fully germinated. After 1.5% it dropped off to 0% for 3.5% and 2.5%.

The two types of seeds that will be used in this experiment are known as monocot and dicot. Monocots and dicots mainly differ in their structural make and their germination process. Monocots, only give sprout
