Vicia Faba Seeds Essay

40 “Yates” Vicia Faba seeds were selected and measured using a millimetre ruler, ensuring that all selected seeds were kept within a size range of 3mm in diameter. Each one of the 8 pots was filled with 8dm3 of soil and given a label using the marking pen, indicating the concentration of gibberellic acid that would be poured into it. 5 Vicia Faba seeds were placed in each pot and buried into the soil at a consistent depth of 1cm. The distance between each seed and adjacent seeds was kept at a constant of 2cm, to prevent the seeds from interfering with each other’s growth. 250mL of tap water from the same water outlet was poured into the 500mL graduated cylinder. 125mg of gibberellic acid powder was taken with a scoopula and measured using …show more content…
Finally, in order to find a response to the research question, the concentration of the solution that yields the highest average germination rate can be determined through graphical interpolation.

Sample Calculation 1:

Calculations performed in order to find the mean germination rate of the seeds for each concentration of gibberellic acid. In this experiment, the germination rate is the average time taken for the seeds to germinate, from the time of sowing. This calculation needs to be performed to generalize the data, in order to create a graphical analysis and a general trend.

Sample Calculation 2:

Calculations performed in order to find the standard deviation of the five trials completed for the 0 ppm solution of gibberellic acid. Here, finding the standard deviation is essential in order to determine how widespread the germinating times are, which may be used
