of water. During the experiment, the results found that even at 6% salinity, there were a few seeds still germinating. 4. The following results were for seeds set to germinate with water saturated with sugar. Trialing period Trialing period for the seed germination only ran for seven days. To do this, coffee filters were wet with 1 tablespoon of salt water from cups that increased in concentration by 1/2 teaspoon of salt in each cup of 8 oz. Sample Abstract of Experiment and Results: The problem was to determine the effect of salt water on germinating radish seeds, and also to determine if there was a maximum concentration that could be tolerated. During the beginning stage of the germination, the seeds take up water rapidly and this results in swelling and softening of the seed coat at an optimum temperature. It starts the growth process by activation of enzymes. Our experiments demonstrated that BO could help to identify the values of the controllable parameters that increase seed germination efficiency. Experiment to study the effect of saline water on seed germination: Requirements: Common salt, distilled water, flask, petri-dishes (9), blotting paper, seeds. The seed activates its internal physiology and starts to respire and produce proteins and metabolizes the stored food. This technique can also be used for investigations into the effect of acid rain. The proposed methodology is model-free, and we argue that it may be useful … This limits the results as there could have been germination at 8%. This stage is referred to as an Imbibition. A series of seed priming experiments were conducted to test the effects of different pretreatment methods to seed germination, seedling growth, and seed yield traits in maize ( Zea mays L.). Results indicated that the seeds primed by gibberellins (GA), NaCl, and polyethylene glycol (PEG) reagents showed a higher imbibitions rate compared to those primed with water. Result: 50% reduction in seed germination in the polluted air confirms that polluted air inhibits seed germination. Think about and then select a physical or biotic factor that you will vary during the experiment. It allows students to make quantitative measurements of root / shoot growth, length of root hairs, etc, as well as % germination. A simple experiment to investigate the germination of seed under different conditions, by growing seeds upright in Petri dishes. The time that results in a positive germination of one set of seeds is when 5 or more of the ten seeds in each pot have broken the surface of the ground. These concentrations could potentially limit the results. On April 25, the day the experiment was started; there was a total of 20 seeds in treatment. This lab exercise involves designing, carrying out, and writing up the results of a simple experiment on seed germination. Independent Variable The independent variable for this experiment will be the amount of water given to the plant every 12 hours, once at 7am and again at 7pm. During this time, 0 seeds germinated the same number of seeds that had germinated since the experiment’s start. Experimental results show that our approach allows to increase the germination efficiency for different types of seeds compared to the initial expert knowledge-based guess. Method: 1.
