pea and Brassica

Figure 2. Comparison of morphological and physiological key processes during the germination of typical endospermless (e.g. Brassica napus, pea and many other legumes) eudicot seeds.
(A) Morphology of a mature pea seed which is endospermless.
(B) Time courses of Brassica napus seed water uptake, testa rupture, radicle growth >2 mm, and the effect of abscisic acid (ABA); control without added hormone (CON).
(C) Visible events during one-step germination typical for endospermless species.
Seed images (A, C) from Finch-Savage and Leubner-Metzger (2006); Diagrams (G) based on quantitative data by Schopfer and Plachy (1984).
