height of a corn seed. To begin, obtain two small planters, each with six individual compartments. Label one planter A and the other B. On the outside of the two small planters label five of the six compartments IAA, NAA, GA, ABA, and Control. The sixth compartment will not be used. These labels respectively correspond to the hormone treatment that each seed will receive. In both planters, fill the five compartments halfway with regular soil. Obtain ten corn seeds and place one seed in the…

Germination is the process in which a plant stems from a seed, and it is fundamental in the development of plants. There are factors that go into how a seed will germinate, one of the most important being temperature. It is said that temperature is an environmental factor that affects germination. Temperature can affect the percent and rate of germination in at least three different ways. The first being that since seeds deteriorate, unless germinated, and the rate of deterioration depends…

Every student should be able to pick a reasonable seed when planting.I think it should be a more spacious place where we plant our seeds. To me the seeds shouldn’t have be already germinated if the were going to grow that fast, so my suggestion would be to not germinate the seeds before we use them.Let the seeds be in the pack before we can even use them.I really think that was a let down, when the seeds had already starting growing before we even planted them. Overall, the project…

Tropical Trees,” a seed should have a certain amount of space between itself and another seed. “No closer than 1 cm to each other, and often 5–25 cm apart, to allow each plant enough room” (Longman, 2003). The thing the author is talking about leaving room for would be germination. For our group’s experiment, we hypothesized that putting a seed next to another seed will have no effect on the rate of germination. Germination can be defined as the development of something, in particular a seed.…

that, “If the amount of water a seed receives is increased, then the amount of seeds that sprout will increase because seeds need water to germinate.” The hypothesis was supported however it is also refuted because, the amount of seeds that germinated declined in numbers at 100 drops/hour. Whereas before it increased for 0 to 71 from 0 drops to 75 drops/hour.The refined hypothesis states that if the amount of water a seed receives increases, then the amount of seeds that germinate will increase…

Germination is a process that seeds undergo when the correct exterior conditions are met and water is introduced, allowing seeds to begin the process of growing into a fully mature plant. When enough water is near the seed it enters the cell by osmosis, specifically a type of osmosis called imbibition when the seeds are in a dormant state. The flow of the water into the seed reinstates a hypotonic environment.This recreates turgor pressure inside the cells causing the cell walls to be rigid,…

concentrations) Auxin- Auxin is a hormone that’s main function is to promote cell elongation in stems, buds and roots and also plays a small part in the differentiation or new cells. Auxin is present in high concentrations in germinating fruits and seeds, but it is not yet known whether this high concentration of auxin is passed on from the mother or whether is is created but the developing tissues. Auxin also helps control what direction growth occurs. Plants “control” growth by changing the…

variety Modern, Khursheed, Ansari, and Shahab studied caffeine’s effect on the Common Sunflower. Seeds of the Helianthus annuus L. variety Modern (the Common Sunflower) were raised with caffeine concentrations from .05-2% to test the mature plant height, days to maturity, yield parameters, and the height on the 30th day of sowing. As a result, seeds treated with a lower dose had a stimulatory effect while seeds treated with a higher dose had an inhibited effect (Khursheed and Ansari et al…

Germination of a seed begins when it is provided water and is in the appropriate conditions. Seeds imbibe the water and the enzymes hydrate, the hydrated enzymes increase metabolic activity to produce energy for the growth process. The root is the first thing to break from the seed and this is when the sed can be officially considered germinated. The environment is what triggers the germination of the seed. How does increasing the salinity of the substrate effect the germination rate of radish…

Title Sugar water versus salt water: What effect did they have on seed germination? Purpose The purpose of this experiment was to figure out what types of water would have an effect and what that effect would be on seed germination. Background information Plants need nutrients to survive. These nutrients can include nitrogen, calcium, phosphorus, magnesium, sulphur and iron. The plant absorbs these nutrients through the roots from the soil. These thing aren’t the only things plants…
