Figure 3 - Effects of GA and ABA on a-amylase
The graph illustrated in figure 3 shows the results of the sample data
collected over four days. As expected, the slope for GA is greater
than all of the other samples. This supports a faster growth rate
for the kernels exposed only to this hormone as its function is known to
stimulate a-amylase production. The slopes
of the other three samples are nearly identical. This suggests that
the ABA found in each suppresses a-amylase production.
However, the slope of the sample data exposed only to ABA is expected to
be considerably less than what is shown due to the higher concentration
of ABA in these kernels.
