Modeling Embryo Architecture in Oilseed Rape.

(A) The development of embryo size and shape. co, cotyledon; ic, inner cotyledon; oc, outer cotyledon; ra, radicle.

(B) Developmental changes in whole seed (black circle), embryo (white), and endosperm/seed coat (gray) fresh weight (FW); means ± sd (n = 10) are provided.

(C) A cut-away three-dimensional model of the seed (20 DAP) showing the seed coat (green), outer cotyledon (light green), inner cotyledon (red), and hypocotyl/radicle (yellow); the volumes of each embryo component were estimated from the model.

(D) Volumes of the various embryo components (in mm³) and whole embryo fresh weight (FW in mg) at various storage stages.

(E) Embryos isolated at distinct storage stages, showing the deformation of the embryo and the folding of the cotyledons (indicated by red arrows).
