Background:
1Germination can be defined as the process of seeds, develop into new plants. In spite of being changeable according to its species, there environmental conditions that needs to be supplied such as temperature, ph and sunlight.1The first process is when water is plentiful, the seed fills with water in a process called imbibiton. In this process seed starts to grow a root. As the plant grows leaves to obtain sunlight. After this point, plant will continue to develop and make its own food by photosynthesis. In order to grow a plant stronger and faster, over the time, people developed different ways. One of these ways is applying fertillizer directly to the plant. Fertillizer is mostly beneficial and widely used so that plants may

Variables How it is controlled? Reason
Temperature Room temperature is controlled by measuring with a thermometer in each day. (23’C) Additional heat may decrease or increase the growth of roots.
Light Seeds are placed in transparent petri dishes at the same time and exposed to the same light level. This allowed to reduce inaccuracy between groups.
Time Germination and growth of roots are measured at lunch period between 12.30 pm.-13.00 pm for each trial In order to make a more accurate measurement.
Volume of Water By using graduated cylinders. Equal amount of water will provide more accurate results. Table 3: Controlled variables and the method to control them
Material List:
1. 500 ml of tap water
2. 1 liter of ammonium sulphate and water solution
3. 1 liter of worm fertilizer and water solution
4. 33x seeds of Boncuk Ayşe1 (Phaseolus vulgaris)
5. 33x seeds of Ayse Kadin2 (Phaseolus vulgaris)
6. 12x couple of petri
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
Although, this experiment is not concluded outdoors, it is provided with efficient light that promotes growth. It’s provided with soil, seed, fertilizer, water and NaCl solutions, to test how salinity effects plant growth.
Figure 1 indicates an increasing mortality rate (positive slope) in plants as density increases; Figure 2 shows the corresponding germination rate reflecting the exact opposite trend. Mortality remains zero until 8 seeds are planted (6% mortality), then is reduced to zero at 16 seeds then increases to 14 percent (32 seeds), 32 percent (64 seeds), and more than half (57 %--128 seeds).
We used wheatgrass were 40 wheatgrass seeds, two empty pots, soil, and water. We first added soil for both pots and 20 wheatgrass seeds in each pot. My partner and I decided that we label pot one experiment which is “sugar and water” and pot two control which is “water” only. The experiment was for almost four weeks we had to make sure both get the same room temperature and water, so we can see the results after this amount of time. Both pots had same room temperature so both can have the same amount of sunlight also, the same amount of water which is a glass of water from the sink once a week. In the experiment pot we added a glass of water with one teaspoon of sugar and the control pot glass of water. Every week we used to see both pots grow almost the same. At the end of the experiment, my partner and I measured the length for both plants and we recorded the average for each plant, so we can know the rate of growth
Every student in a lab section planted eight seeds, two in each cell in a quad, to make sure that we had at least one plant for each week for 4 weeks. After planting the seeds we put the plants on a water mat tray to make
This experiment was developed by trying to make gardening more interesting by growing cucumbers faster with different items that can help other plant. By figuring out how to grow
the effect light has on the growth of pea plants. It will take place in an environment with controlled light, with equal amounts of plants being grown in the light and in the dark. All elements of the experiment other than light will be kept the same, such as amount of seeds in each pot, amount of soil in each pot and amount of water given to each plant each day. This will ensure a fair experiment. Prediction: I predict that in general, the plants grown in the light will grow better than those grown in the dark.
The cultures were maintained at 25±20C under 16 hr illumination of 4000 lux intensity. The results are presented in Table 1, it can be seen from the data that pH of the medium had significant effect not only on regeneration frequency but also on number of shoots developed in each culture. Maximum 62.5±4.7 percent cultures in CoS 98259 and 67.3±4.9 percent in CoS 767 developed shoots at pH 6.0 while regeneration frequency was the lowest at pH 5.6. An increase in pH form 6.0 to 6.2 and 6.4 reduced the frequency of shoot regeneration from the callus (Table
I chose to measure this growth by observing the number of stomata present on the underside of leaves exposed to the dark and to sunlight. Based on the idea that there are more open stomata present on leaves exposed to the sun, my hypothesis that 'Factors which might affect stomatal opening' (Light) there will be more stomata on the plants exposed to the light. Hypothesis = == ==
To delve into the clockwork of this technology we must start from the beginning. A plant starts its life as a single celled organism; the sperm within pollen fertilizes an egg. This egg (cell) divides to form the tissues and organs of a species. As development proceeds cells grow unique of one another and change. Different cells make up different things (ex cells in the stalk of the plant are much different than those of the piston) and these differences are attributed to the fact the different amounts of proteins in each cell.
The seeds were tested over a two-week period to see how they would react to the different variables that were picked. After the two weeks the results were compared between the Lab group to see how each person’s variables either hindered the seeds or helped them grow. The purpose of this experiment was to describe and test what environmental factors
Tissue culture allows for the growth of a plant without the use of seeds or pollination.
Seed certification is a quality assurance process. Seed intended for domestic or internationalmarkets is controlled and inspected by official sources in order to guarantee consistent high quality forconsumers. This is done by i) controlling the seed in previous generations; ii) carrying out field inspectionsduring the multiplication process to ensure there is little contamination and that the variety is true to type;iii) growing samples in control plots of the known seed to ensure that the progeny conform to thecharacteristics of the variety and iv) seed quality testing in laboratories (OECD,
By the time spring came, my father was regaining his strength. My father and I tilled and prepared the soil, then began planting the seeds. Though I wanted them to sprout immediately, they had their own timetable. When they finally did, I was so excited to see them pushing their way up through the dirt and climbing towards the sun. We cared for the seedlings, giving them manure, aerating the soil, watering them daily, doing everything we could so they would keep growing. But my father would point out that the first rule of gardening is that we are not in control. We can only wait and watch and enjoy each moment. As the plants grew stronger, I felt myself growing stronger as well. Slowly, I was learning to wait and coming to understand that the growth process, like life itself, has a force and rhythm of its own, and that I could rely on it.
Asexual propagation is the process through which reproduction without passage through the seed cycle occurs. The advantages of asexual propagation are that it preserves genetic makeup, propagates seedless plants, disease control, rapid production, the plants are identical, cheaper, faster and easier reducing or avoiding juvenility. The disadvantages of asexual propagation are that it increases disease and insect susceptibility, plants are bulky, and the mother plants could become contaminated. The goal of this experiment was to determine the development of adventitious roots and shoots, and observe these plants over a period of five weeks. Due to auxin being produced in the tip, tip cuttings should root faster than any other cuttings. Auxin is a plant hormone that is responsible for cell elongation and enlargement, root formation, and growth. There are two forms of auxins; phototropism, which is produced in the tip and moves downward on the side away from the light and gravitropism, which is where plant roots grow downward and plant shoots grow upward.(Plant Auxin 201...
