Introduction
Gibberellic acid(C19H22O6) was discovered back in the 1930s by Japanese plant pathologists. In the late 1800s, a disease called Bakanae, also known as the “foolish seedling” infected the rice crops in Japan, Taiwan and other Asian countries. The plants die after demonstrating extended growth patterns. Shotaro Hori, a Japanese plant pathologist, proved a type of fungus was the cause of the disease. The fungus was later named Gibberella fujikuroi. Years later in 1926, another plant pathologist named Eiichi Kurosawa identified the hormone in the fungus that caused the disease. (Melody Lee, 2010) Since then, over 130 additional Gibberellic acids have been identified from other fungus and numerous vascular plants, as well as bacteria. …show more content…
Number of accumulated germinations of poppy for each concentration of Gibberellic acid (group data)
Graph 3. Number of accumulated germinations of radish for each concentration of Gibberellic acid (class data)
Notice that the trend are similar for all .
Graph 4. Number of accumulated germinations of poppy for each concentration of Gibberellic acid (class data)
Discussion
Regarding to graph 1 for radish seeds, the data suggest that the seeds without any gibberellic acid are the ones that germinated the fastest. According to the R value, all the other trendlines with Gibberellic acid have the same trend. This shows that Gibberellic acid have an negative impact on the germination of seeds. Only 9 seeds from one sample of 1000 ppm germinated, therefore the average never reached 10.
From graph 2 it can be concluded that poppy seeds are slower at germinating compare to radish in general. All of the trendlines are similar in curve, however the R value shows that the sample 0 ppm is the one with the slowest speed.
The class data is more accurate in showing the growth of plants because there are more samples. Graph 3 shows that Gibberellic have no affect on the germination speed as the R value range is within
