The effects of salinity on wheat germination essay

Water — to metabolically activate the cells within the seed 2. All results have been rounded to one whole number, as living organisms including seeds can only be counted whole numbers.

As you can see, though it would appear our results are more extreme, their results to reflect our negative trend. Take a photograph of all the Petri dishes with seeds and then print and annotate the pictures with thereby labelling them giving them each a code i.

Gibberellic acid in tern causes the synthesis of amylase, which breaks down the starch contained within the cotyledon into maltose. The line of best fit is reasonably accurate and it passes through all of the error bars. The line of best fit is not accurate and it does not passes through all of the error bars and point.

I would ensure that all of my seeds smooth seeds that matched the dark olive green of the seeds below. Place 10 seeds per tray evenly into Petri dish on top of the paper towel see part 2 of 1.

As discussed, temperature is important as germination is an enzyme catalysed process and thus the enzymes work fastest at their optimum temperature, with lower temperatures causing the enzymes to work slower. The ovary contains chambers called ovules that develop into pinto bean seeds, which mature in the bean pod.

As at 0, the error bar is very large 1SD is 2 this indicates that the values recorded for this percentage was less valid and some other factor may have been affecting the results. Parts of the Experiment The dependent variable in this experiment is plant growth, measured in height of the plant and number of leaves of the plant.

However as we utilised the same amount of solution in all trials, all trials would have been equally effected. They used a CAM pathway, or a day and night cycle which only opens the stomata at night.

This means that some seeds would have been better insulated than others. Type of water The same type of water will be used for all of the plants i. The maltose can then be hydrolysed to glucose for respiration of polymerised to form cellulose, necessary for plant walls.

Therefore though it is difficult to conclude exactly what effect varying thickness in cotton wool would have had on our results, it is most likely that it would have decreased the number of seeds germinated, causing our mean to decrease, effecting our validity.

Although some level of variation is expected due to seeds being biological in nature, this level of range is unprecidented and indicates that this trial in particular was effected by other factors. Two of our 0. I would leave the lid slightly agar and place the container in storage.

Our results are supported by multiple experiments, including this one conducted primarily by the Department of Agronomy in Zabol University, Iran. Standard Deviation From — http: 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.

For germination to occur the seed must have the correct abiotic conditions to begin. Graph 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 mean number of seeds with the visible presence of a radicle seven days after the solution was added to the seeds Comment on the graph As we had no radicles present at 0.

Place Petri dish on top of paper towel and trace outline with marker.

Varying cotton wool thickness The cotton wool varied in thickness across the different petri dishes. The tolerance of the bean plants as well as the growth of the experimental plants compared to the controlled plants will be tested.

However, this may have caused the complete lack of germination in the 0. However there were still some anomilies which would have caused our error bars to increase.

A small root called the radicle forms and a hooked stem grows. In my experiment I investigated whether changing the salinity of water effected the germination capabilities of mung beans, originially this was going to be indicated by the visible presence of a radicle, 10 days after being exposed to the solution, however these results were inconclusive so we also indluded our data from the fourth day which measured how many seeds testas had begun to crack.

Therefore when we placed our seeds in high salt solutions there was a high concentration of salt in the area surrounding the seed, which would cause movement of water out of the seed, and thus water, which is necessary for germination would not be absorbed in the needed quantities, inhibiting germination.

The independent variable is the salinity of the water that the different plant groups are being watered with. If I were to repeat this experiment I would use large circular cotton wool pads[4], which would evenly cover the petri dish, causing there to be even insulation and absorbance of solution.

All of our seeds also gave off an unpleasant odour after 4 days which continued to the tenth day. To ensure an even cover of solution on the cotton wool I would utilise a spray bottle[5] containing 5ml of solution, which I would hold 10cm above the centre of the petri dish, and spray my solution to ensure an even cover.

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 plants will all be receiving the same amount of sunlight, the same type of environment, and same type of soil to grow in.For the 2% salinity, mix 5 g of table salt in mL of water, and water each 2% salinity plant with mL of the 2% saline water.

For 5% salinity, repeat the procedure in step 9, but with 60 g of table salt. For 20% salinity, repeat the procedure again from step 9, with 90 g of table salt. vious reports in lentil [25], Wheat [26], Sorghum bicolor [27]. The reduction in root and shoot development may Effect of Salinity on Germination, Seedling Growth and Acid Phosphatase Activity in Lettuce Acid Phosphatase, Germination, Lettuce, Salinity.

Wheat • Salinity • Germination • Seedling INTRODUCTION Salinization is the scourge of intensive agriculture [1]. High concentration of salts have detrimental effects on germination of seeds [2, 3] and plant growth [4].

Many investigators have reported retardation of germination and growth of seedlings at high salinity [5]. Therefore, high germination rate and vigorous early growth under salty soils is response of five genotypes of wheat (Triticum aestivum L.) to NaCl salinity at germination and early seedling growth was investigated.

Salinity effects were evaluated on seed germination and seedling growth of six bread wheat cultivars (Triticum aestivum L) including Hirmand, Chamran, Hamoon, Bolani, Sorkhtokhm and Kavir. The.
