Hypothesis: My hypothesis was that
the wheat seeds would germinate the fastest due to their size
. Procedure: The experiment was conducted as follows: Placed six (6) of each seed type in 50ml of water to soak for 24 hours.
What affects germination hypothesis?
Part 1: Consider a Question / Hypothesis
Several variables might affect the germination, these variables include
light, temperature, water, soil type, and air quality
. … Remember, that the hypothesis should be a complete sentence that can be tested.
What is the aim for seed germination?
The activation of metabolic machinery of seed embryo
is the first and foremost step to initiate the seed germination process Thus, seed germination is the process of reactivation of the metabolic activity of the seed embryo, resulting in the emergence of radical (root) and plumule (shoot), thus leading to the …
What is the science behind seed germination?
When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat. The embryo's cells start to enlarge. Then the seed coat
breaks open and a root or radicle emerges first
, followed by the shoot or plumule that contains the leaves and stem. Many things can cause poor germination.
What is a good hypothesis for seed germination?
Good hypotheses are
“If… then… because”
statements. For example: “If I water some plants more and some plants less, then the plants that receive more water will grow taller because plants need water to grow.”
What are the 5 stages of seed germination?
The process of seed germination includes the following five changes or steps:
imbibition, respiration, effect of light on seed germination, mobilization of reserves during seed germination, and role of growth regulators and development of the embryo axis into a seedling
.
What are the 6 stages of germination?
For humans, the progression is infant, toddler, adolescent, young adult, middle aged adult, and senior citizen, while plants go from seed to sprout, then through
vegetative, budding, flowering and ripening stages
.
What are 3 factors that affect seed germination?
Environmental factors such
as temperature, light, pH, and soil moisture
are known to affect seed germination (Chachalis and Reddy 2000; Taylorson 1987). Burial depth of seed also affects seed germination and seedling emer- gence.
Does heat speed up germination?
Tips for Warming Soil to Speed Up Seed Germination
Seeds need both moisture and warmth to germinate.
Warm up the soil before sowing your seeds
. … Keep in mind that high temperatures will kill seeds or dry out seedlings, so stay in the desired temperature range. More is not more.
What happens if you give a seed too much water?
When the seed fills with water in a process called imbibition, it activates enzymes to initiate the germination process. On the other hand, too much
water can cause seeds to rot instead of developing into a seedling
. So, suitable moisture is needed to get the best results.
Do seeds need sunlight to germinate?
All seedlings require sunlight
. Seedlings will become leggy and fragile and will not produce to their potential if they do not have sufficient light. Table 1. Soil temperature conditions for vegetable crop germination.
Why are not all seeds germinate?
Many variables can affect the germination rate of seeds. How the seeds were stored, their age, the depth at which they were planted, the weather, the soil they were planted in, moisture, and temperature can all play a role in the success or failure of germination.
What do seeds look like when they germinate?
They'll usually turn yellow or brown, dry up, and eventually fall off (a process that can take several weeks, depending on the plant). As long as the true leaves are still
green
and healthy-looking, your seedling is developing normally.
What is hypothesis example?
- If I replace the battery in my car, then my car will get better gas mileage.
- If I eat more vegetables, then I will lose weight faster.
- If I add fertilizer to my garden, then my plants will grow faster.
- If I brush my teeth every day, then I will not develop cavities.
Where did the most seeds germinate?
Most seeds germinate best
under dark conditions
and might even be inhibited by light. A few other seeds need light to germinate. But once seeds have germinated and broken through the surface of the soil or growing media as seedlings, they all need sunlight to grow.
How do you write a seed germination experiment?
Dampen a
paper towel
and fold it into the bag. Place the seeds along one side of the bag, pressing them against the paper towel. Seal the bag tightly and hang in a window using tape. Make sure the beans are visible on the side of the window where your child will be observing their seeds sprout.
