Histochemical Sudan Red staining of lipidic substances. Cultivated pea (Pisum sativum subsp. sativum): cv. Cameor (A,E,I,M,Q), JI92 (B,F,J,N,R); wild pea (Pisum sativum subsp. elatius): JI64 (C,G,K,O,S), JI1794 (D,H,L,P,T). Development series were analyzed at 13 DAA (A–D), 21 DAA (E–H), 27 DAA (I–L), 30 DAA (M–P), and dry seeds (Q–T). Staining variability within one seed segment in genotype JI64, 13 DAA (C) and 30 DAA (O). Scale bars = 50 μm. Abbreviations: ms—macrosclereid cells, ost—osteosclereids, par—parenchyma, gr—gritty, ll—light line.
