Values are expressed as ± standard deviation; EL: embryo length; EW: embryo width; SV: seed volume; EV: embryo volume; AS: air space; percentage air space was calculated as ((seed volume−embryo volume)/(seed volume)) × 100. N = 30. The data followed by the same letter in a Duncan grouping are not significantly different (α = 0.05).
