Effect of Salinity on Germination Essay Sample Colour used to indicate the raw data used to calculate example mean Colour used to indicate the raw data used to calculate example standard deviation Raw Data table 2 showing the effect changing the salinity of water added to ten ungerminated Vigna radiate mung bean seeds has on the seeds ability to successfully germinate as determined by the visible presence of a radicle seven days after the solution was added to the seeds? Salinity of Water mol L-1 Mean number of mung bean seeds with a cracked testa four days after being exposed to the solution Key Colour used to indicate the calculated example mean Colour used to indicate the data used to calculate example standard deviation Note:
This experiment will be performed in order to determine the tolerance and growth of bean plants on different salinity levels from water containing salt.
The irrigation of saline water improves soil structure, but can negatively affect plant growth and crop yield. Excess energy use in plant may eventually lead into plant stress and cause vegetation to become unhealthy and die. A high salt level in the water or soil may then interfere with the germination of new seeds.
Some causes of salinity in the water or soil is due to Natural processes such as the weathering of rocks, wind, and rain. Salinity also may occur when long rooted plants are replaced with short rooted plants which will then cause the water table to rise and bring the salt to the surface.
Although that may be one of the effects of salinity in water, plants are able to adapt by producing a quantitative trait loci that increases survivability against salinity. Stretches of DNA are connected and linked to genes that contain the phenotype of being able to survive the salinity.
Mesembryanthemum crystallinum or the ice plant has also shown its adaptation to salinity. They used a CAM pathway, or a day and night cycle which only opens the stomata at night. This saves water that they intake and increases their water use efficiency to support tolerance against salinity stress.
Plants have adapted to survive against salinity through facilitation of water intake. In this experiment bean plants will be used to determine the tolerance and growth of the plants of different salinity levels from water containing salt as said previously before.
The technique that will be used to perform this experiment is receive a total of bean plants planted in plastic cups containing natural unfertilized soil. The tolerance of the bean plants as well as the growth of the experimental plants compared to the controlled plants will be tested.
The plants will all be receiving the same amount of sunlight, the same type of environment, and same type of soil to grow in. How the data will be recorded is by first allowing the plants to sprout and grow. The seed to seedling development takes about two weeks. The bean begins to absorb water when planted in warm, moist soil, and the absorption of water signals the metabolic start of growth.
Pressure builds inside the seed until the seed coat bursts. A small root called the radicle forms and a hooked stem grows. Then the seeds split and two small leaves, or cotyledons, appear.
Afterwards, sets of true leaves cause rapid new growth. The roots deepen into the soil, and side shoots grow and the stem thickens. The plant develops special bacteria to regulate the amount of nitrogen within the plant.
After another days, the flowering begins. The bean plants can fertilize themselves, but cross pollination makes fertilization more successful. The ovary contains chambers called ovules that develop into pinto bean seeds, which mature in the bean pod.
After hardening and drying, they become pinto beans.Effect of Acid Rain on Seed Germination Essay. To stimulate the effect of acid rain on plant life, students to set up a lab experiment to compare the effect of varying levels of acidity on plant seed germination. Salinity mainly affects and reduce the percentage germination rate and also lowers the onset of a given germination.
The effects of salinity on germination can be modified or reduced by use of other environmental factors to counter the effects, such environmental factors may include light and srmvision.comon: Madison Avenue, New York City, , NY. Key words- Salinity, Seed sprouting, Germination rate, Ipomoea aquatica, Sodium chloride.
Research AND RATIONALE. The aim of this work is to carry on a bio-assay to look into the relationship between salt and the sprouting rate of kang kong seed hence finding the best salt for maximal seed sprouting. N. Nasri et al.
58 to salinity. Salt stress has been shown to decrease the germination percentage and germination rate of some crops . Soil salinity may influence the germination of seeds either by creating an osmotic potential external to.
Salinity in water used to irrigate plants and soil salinity can have a considerable effect on the intensive agriculture of wheat plant germination and growth (Effect of salts on germination of seeds and growth of young plants of Hordeum vulgare, Triticum aestivum, Cicer arietinum and Brassica juncea.
Factors Affecting Seed Germination Lab Essay Factors Affecting Seed Germination Research Question What is the effect of dark and light on the germination of radish seeds? Hypothesis I predict the seeds grown in the light will germinate twice as much as the ones grown in the dark.
