Note: H1 = CGAT; H2 = CGAG; H3 = CGGT; H9 = TTAT; H10 = TTAG; H11 = TTGT; H12 = TTGG; Means with different lowercase letters within the same column are significantly different (P < 0.05). Means without lowercase letter and means with different lowercase letters within the same column are not significant difference (P > 0.05).
