Temperature Effects on Radish (Raphanus sativus) Root Development Abstract Several studies have been conducted to establish how temperature‚ seed germination‚ and root growth are related. Because temperature plays a main role in many growth processes‚ we decided to focus on how it affected root growth. Radish (Raphanus sativus) seeds were chosen due to their ability to produce a distinct bulbous tuber‚ and their relatively short growing time. Three test groups were placed under different temperature

phytoremediation. The minimum amount of lead (0 mg/gm) was found in plant treated in 0 % concentration of lead acetate and maximum amount of lead (0.0011 mg/gm) was found in plant treated in (0.6%) concentration of lead acetate. The percentage germination for control‚ 0.2‚ 0.4‚ 0.6 percent lead acetate treated seedling was 89%‚ 88%‚ 86.66% and 83% respectively. The length of shoot was found much less in plant treated in 0.6% concentration of lead acetate (10 cm)‚ as compared to the length of shoot

Question/Purpose: The Question or Purpose of our lab is to answer the question “How is the germination of a seed affected by sunlight?” Experimental Hypothesis: We believe these results will occur. 1. The seeds that are water deprived (1 mL of H2O a day) will not grow very well due to a lack of water which is important in photosynthesis and also lacks nutrients. The seeds may also die off due to a lack of water. 2. The seeds that are have a proper amount of water (10 mL of

Using different chemical seed soaks to improve the rate of germination A 2013 Year 9 Science Project by Josh Martin Class Level 1 with Mr Box Abstract: The purpose of this investigation was to determine which out of five readily available chemicals was the most effective at scarifying seeds to improve the rate of germination‚ and what concentration of the most effective chemical was the most efficacious. Ten seeds for each of the five chemicals hydrogen peroxide‚ glucose

moist sand 12 cm. deep in which a given number of seeds are planted.PERCENTAGE OF GERMINATION – To find the percentage of germination of a particular seed ‚ usethe rag-doll method of testing seeds. • To calculate the Percentage of Germination ‚ use the formula : P.G. = GS / SS × 100 • In rolled towel test ‚ 56 seeds germinated out of 125 seeds planted. Find the percentage of germination . Solution : P.G. = 56 / 125 × 100 = 44.8 • The new seeding rate (

was to have found out how different chemical solutions help or harm radish plant growth when the seeds of the radish plant are soaked in said solutions prior to planting. Background: The IRP project I am doing is based off the subject of seed germination. The seeds I will be planting are cherry belle radish seeds‚ freshly bought. Instead of planting the seeds in soil like it is normally done‚ the plant seeds will be placed on paper towels to grow for better observation of the roots‚ and for a quicker

communications among the team‚ the seeds‚ soil‚ water concentration‚ fertilizer‚ light exposure‚ temperature of the room‚ consistency of following watering (watering the plant same time every day) and seed depth. All of these variables can affect the germination process in some sense but seed depth is the greatest‚ on the back of the seed packet it states the proper depth to plant the seed so it may break the surface and continue growing‚ without this there is no study. Hypothesis: Compared to the recommended

fertilized ovule that contains an embryo and transforms it into a new plant through the process of germination. Seeds remain inactive until conditions are right for germination. All seeds need water‚ oxygen‚ and proper temperature in order to germinate. However‚ some seeds require full light or darkness to germinate. According to Holm (1996) seeds have chemical inhibitors that prevent germination. A seed will not grow unless those inhibitors are destroyed by things like temperature changes‚ moisture
