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 (

Effect of pH on Green Pea Germination Objective: To determine how pH affects the germination of green peas and to examine the degree of germination within each pH level. We will do this by using various buffer solutions (along with distilled water) to grow green peas. Hypothesis: We expected that the group of peas that encountered a pH of 7 to have the most and highest degree of germination. Materials: tap water buffer solutions pH 3‚5‚ 7‚ 9‚11 distilled

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

Introduction: The world’s total forest area is just over 4 billion hectares‚ which corresponds to an average of 0.6 ha per capita (Figure 1). The five most forest-rich countries (the Russian Federation‚ Brazil‚ Canada‚ the United States of America and China) account for more than half of the total forest area. Deforestation – mainly the conversion of tropical forest to agricultural land – shows signs of decreasing in several countries. Around 13 million hectares of forest were converted to

effect on radish seed germination rates? 2. Does exposure to such radiation have a measurable effect on radish seedling growth? 3. If you can demonstrate any effect‚ is it dependent on the level of radiation exposure? 4. Do individuals in the population exhibit variations in their tolerance to radiation exposure? First Hypothesis: Ho: Seed germination has nothing to do with gamma radiation (50‚ 150‚ and 500) HA: Gamma radiation will have an effect on seed germination Second Hypothesis:
