  1. SC, EMC, ENC, AR, DE, and SP stand for subcutaneous cavity, embryo cavity, endosperm cavity, aspect ratio, density, and Sphericity respectively. Mean in the same column followed by different lower case letters indicate a significant difference (P < 0.05). All data above was also showed by figure in the Additional file 1
