Figure 2

Microscopic images of different developmental stages of somatic embryogenesis in R. sceleratus, obtained using frozen section technique. (A) Multiple embryoids induced from leaf explant; (B) Globular embryo; (C) Transitional globular-heart embryo; (D–G) Heart embryos; (H) Torpedo-shaped embryo; (I–L) Cotyledon embryos. Bar (A) = 100 μm; Bars (B,C) = 50 μm; Bars (D–G) = 75 μm; Bar (H) = 200 μm; Bars (I,J) = 200 μm; Bars (K,I) = 400 μm.
