Factors affecting seed and seedling vigour

This experiment is designed to test the allelopathy of two different treatments, Eucalyptus (Eucalyptus cinerea) and Lemon (Citrus limon). The two treatments will be tested on radish seeds (Raphanus sativus) to investigate the effect of the treatments on the germination of the radish seeds. Allelopathy is the beneficial or harmful effects that one plant has on another plant by the release of chemicals. Allelopathy studies the interactions among plants, fungi, algae and bacteria with the organisms living in a certain ecosystem, interactions that are mediated by the secondary metabolites produced and exuded into the environment (Francisco A Macías, José MG Molinillo, Rosa M Varela, Juan CG Galindo 2007). The plants use

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.

When planting a seed, many factors allow the seed to grow and become a plant. To sprout from the ground, and to survive, seeds need water, air, and a certain temperature. Seeds can get water, oxygen, and sun by being placed at the proper planting depth. Planting depth is the depth at which a seed is placed in the soil. If a seed is exposed to these important needs, it goes through a process called germination. According to the Wise Geek article, “What is Germination?”, “Germination is a process in which a seed or spore awakens from dormancy and starts to sprout.” (“What is Germination?”).

The results obtained are non-conclusive. More research is necessary in order to fully understand the effects of Nitrogen in the development of Fast Plants seeds and the soil. It is recommended that original is repeated. However, only one fertilizer should be added per quad, rather than mixing the fertilizer used for the control with the fertilizer being studied. For future studies it is also recommended to maintain a record of the pH of the soils before, during, and after the experiment in order to understand the impact of fertilizers on the

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.

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 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.

the herbicide. After the creation of glyphosate and the creation of the GM seeds, resistant seeds

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

To what extent to different concentrations of Eucalyptus microcorys (E. microcorys) at 0g/mL, 0.25g/mL, 0.5g/mL, 0.75g/mL and 1g/mL have an allelopathic effect on the germination of Raphanus sativus (R. sativus) seeds as measured by the number of seeds germinated within seven days?

Critics fear that continual use of chemicals could result in “super weeds” and “super bugs”.

Purpose: To see the effect of an acid introduced during seed germination, on the length of the plant roots. Also shows how salt can affect the seed germination. Acid can be introduced to seeds during germination if there is acid rain. Knowing the results of acid rain on seed germination will help us understand how to grow pants better, and how to have more successful germination. Salt can be introduced into a seed during germination because salt is put on roads and the salt builds up and can contaminate the soil. Knowing the effects of salt on seed germination will allow us to know for sure if the salt is affecting the plants growth or not.

A study was conducted at Gomal University that tested the allelopathic effects of Eucalyptus camaldulensis L. on the germination and seedling growth of wheat. The leaves of E. camaldulensis trees were washed and dried and then filtered to create a one hundred percent solution as well as ten percent, fifteen percent, and twenty percent. These solutions were tested on twelve varieties of wheat. The results showed that there was a significant decrease in germination counts with increasing levels of Eucalyptus aqueous extract concentration. All twelve varieties of wheat were adversely affected by the twenty percent concentration of Eucalyptus extract. It was observed that there was a direct relationship between the number of normal seedlings and the extract concentration. The results suggested that the E. camaldulensis L. leaf aqueous extract could reduce normal seedlings even in low concentrations.
