Values represent the means of three replicates ± standard deviation. Mean values followed by different superscripts within columns are significantly different according to Duncan’s Multiple Range Test (p < 0.05), represented with a–c. Repeated superscript letters indicate that the means were not significantly different (p > 0.05). MCSC: Malabar chestnut seed coat; MCE: Malabar chestnut embryo; WMC: whole Malabar chestnut.
