Conclusion and Evaluation: The aim of the experiment is to observe how does using the same plants and conditions except watering them with different amounts of water will affect the ate of germination. The amount of the temperature,oxygen and light(by placing all the plants into the same place) is controlled. Some errors may caused by; * The plants were kept in room temperature 230 as measured but the temperature may varied in night and day. * The plants were placed in front of the window so each plant may take the sunlight with different slope.
This may caused some plants to get more sunlight than the other plants and light effects the germination. Also this may caused a greater temperature on some plants . 10 days is a short period of time to get accurate results because it took too much mime for the plants that watered with 40 ml water to germinate. * If a ruler with smaller scale was used we could get more accurate results.
Some improvements could be; * If the temperature would be kept constant by a heater in an isolated place. To prevent the plants from taking the light with different slopes is to place a light source above of every plant. If the experiment lasted more than 10 days the plants could grown more so the difference in heights of the plants for different amounts of water could be seen more precisely. * If even more amount of water levels could be used there would be more information to prove the hypothesis.
The first sign of germination is the absorption of water. This activates an enzyme, respiration increases and plant cells are duplicated. Soon the embryo becomes too large, the seed coat bursts open and the growing plant emerges.
The tip of the root is the first thing to emerge and it’s first for good reason. It will anchor the seed in place, and allow the embryo to absorb water and nutrients from the surrounding soil. Some seeds need special treatment or conditions of light, temperature, moisture,water etc. To germinate. Seed dormancy is very complex, but it protects that living plant material until conditions are right for it o emerge and grow. *** In the experiment it has been observed that as the amount of water increases so does the rate of germination.
When the adequate amount of water is reached ,which means the cotton soak up enough water the germination rate is maximum after 10 days. But when too mulch water is used the germination rate starts to decrease. The maximum rate is observed during 20 ml water ,while in ml and 40 ml of water the germination gets slower. Monitoring water content of seeds is a must. Too much water can cause the seed to drown and not grow or can cause mold problems if not careful. Too little water and the seed won’t grow. The soil should be damp to the touch. *** That’s why plants that 30 ml and 40 ml water is used the water level was over the cotton layer in the glass, so the water was too much for the plants causing them to not germinate easily and have some mold problems as the color of the cotton layer starts to get darker. In the end of nova p value 4,EYE-1 5; 0,05 so hypothesis is rejected and hypothesis alternative is accepted. Let is observed that changing the amount of water does effects germination as significant difference is observed between different amount of water used.
