3. We will attempt to answer the following questions: How does seed age affect radish (or lettuce) seed germination and rate? Then the embryo will grow and develop its first set of true leaves, using food stored in the endosperm for energy. Seed Germination Times It has been hypothesized that the standard deviation of the germination time of radish seeds is 8 days. Put this worksheet in your science notebook. In the Petri dish labeled “hollycock”, Experiment Group A. the group tested a total number of twenty (20) radish seeds (Raphanus sativus), out of the twenty (20) seeds, there was only a twenty-five (25) percent of germination, and only five (5) seeds had actually germinated. When soil has too much salt, crops won't grow well. The LD 50 for the class data was estimated to be 15.0 g/L, which means that 50% of radish seeds are expected to die when the salt concentration is increased to 15.0 g/L. From the results, pH 3 radish never grew at a slow rate radish on pH 10.5 grew at a slower fairly rate and pH 6. Students will determine the pH of rainwater in their local area. The seed of a plant is the embryo, and it contains enough energy for the plant to survive until it is time to start growing. You will pick ONE of these independent variables and test it. 1. Place 5 snow bean seeds in each pot 2cm deep. 6. Drop 10 drops on each seed every day using a pipette. The hypothesis that was stated in the beginning was proven to be correct as we have learned that allelopathy of garlic indeed has an effect on the germination of radish seeds. For example, mustard seeds show good germination after even 50 years. The following results were for seeds set to germinate with water saturated with sugar. 811 certified writers online.

If the soil is any warmer than this, seed germination rates will decrease. Combined with high humidity, high temperatures can encourage the growth of mold, which is another threat to your Radish plants. The ideal temperature for Radish seed germination is between 18°C and 29°C. 1980). Titicaca) (provided by Department of Plant Environmental Science, University of Copenhagen) were stored at 5 °C until the start of experiments.Two different experiments were carried out in a growth chamber (Green line WRS 96-85, KW, Scientific Equipment, Italy) (temperature of 25 ± 1 … The data collected could not prove the hypothesis, which stated that i f radish seeds are exposed to 12.5% of the salt solution, then 50% of the radish seed population will die, but, the seeds germinated radicles will be much larger than those of the control group. Here, you can observe seed germination, in which the embryo begins to digest the food and grow into a seedling. It is seed that is over a year old, a wet paper towel germination test can be used to test the seed. Seed Germination Lab Report. Germination is when the seed starts to sprout, and a plant starts to emerge from the seed. Next, place a folded paper towel in each petri dish. This lab shows the LD50 of Radish seeds when given different doses of salt water. 4) Put a few fertilizer pellets in each dish. The process by which an organism grows from a seed into a plant is called germination. Specific Analysis and Conclusions: 1. Introduction: In this lab, we studied the effects of of salt water on the germination and radical length of radish seeds. The dependent variable for this investigation is the time that the seeds take to germinate. Observe the seeds for 2 days. Plant Physiology 66: 220-224. Abstract: Gibberellic acid is a plant hormone that is used to stimulate growth and fasten the germination of plants. In vinegar, only 10% of the seeds germinated 40% in baking soda and 100% in water. Next day, a small white structure emerges from each seed. We will attempt to answer the following questions: How does seed age affect radish (or lettuce) seed germination and rate? 2.

For example, mustard seeds show good germination after even 50 years. HL IB Biology II - Seed Germination Lab Part II. Bibliography. By overlooking the outliers in the group data, it is obvious that the trend in germination is that less seeds will germinate as they are exposed to higher levels of salt. A bean seed will grow into a bean plant. seeds to each bag. Germination is the process of growth of plants from the seeds. a. Observe the geotropic responses of roots and shoots of Radish seedlings in laboratory. Experiment 1: Effects of pH on Radish Seed Germination. This would suggest why 25% of seeds germinated after five days in an environment containing 1% NaCl, but 0% of seeds germinating in 5% NaCl and 10% NaCl. The You will want to thin the radishes when they have grown about 1 inch. ...If you're planting a large radish you will want to plant the seeds about 1 inch to 1 1/2 inch deep.Radishes work well as companion plants, because they keep a lot of the bugs off the regular plants and they grow more quickly. Plant them alongside carrots, parsnips, and cabbages. Purpose: This laboratory will test the effects of various household chemicals on the germination and growth of radish seeds in the laboratory. Results: Include the class data. The radish seeds will not germinate at all in a solution with more than 3 teaspoons of salt in 8 oz. Dormant seeds contain all the materials required to start new plant growth including starches. Radish Seed Germination Lab Report 2 Abstract An experiment was performed to investigate the effect chemicals had on radish seeds. Place the foil packets in a box or drawer. During germination, the white structure that appears first develops into root. Design Lab involving Germination To germinate, a seed requires three things – water, oxygen, and a suitable temperature. Some seeds take a very long time to germinate, while others germinate very quickly. In part, dormancy can be maintained by a hormone, abscisic acid (ABA), which permeates the seed coat. Measure and record all pots every day with a camera, ruler, pencil and paper. After you microwave each group of seeds, place the seeds into the matching bag with the correct label, close the bag, and place it in a desk drawer. Here is a little run down of our results, though yours may, of course, be slightly different. 5. The purpose of this lab was to determine what effect salt had on the process of seed germination. 6.
