Values are means ± standard deviations (n = 3). Means with the same letter in each column, within treatment, are not significantly different between genotypes (p < 0.05) (LSD test).
ns, not significant; LSD, least significant difference.
*, **, and *** indicate significance at p < 0.05, p < 0.01, and p < 0.001 levels, respectively.
