Reported values are presented as mean values ± standard deviation. Mean values with the same capital letter in a column are not significantly different as indicated by Tukey’s test (p < 0.05). Mean values with the same small letter in a row for each measured trait are not significantly different as indicated by Tukey’s test (p < 0.05).
