Each datum represents an average ± standard error (n = 3). The results of t-test and type of t-test used (S, Student’s t-test; U, t-test with unequal variance) are also shown.
W/G ratio, ratio of the average values for green and white sectors
aNot subjected to statistical analysis due to lack of variance, but apparently different
