Lily developing embryo
NettetUsing light microscopy, ovule and embryo sac development are described in five (of 12) species of Trithuria, the sole genus of Hydatellaceae, and compared with those of Cabombaceae and Nymphaeaceae. Key Results The ovule of Trithuria is bitegmic and tenuinucellate, rather than bitegmic and crassinucellate as in most other Nymphaeales. Nettet5. aug. 2024 · The lilies in this study were all commercial cut lilies, and the heart-shaped embryos were persistent and easy to observe. During the somatic embryogenesis of Lilium longiflorum ‘Easter Lily’, the heart-shaped embryo also can be clearly distinguished under microscope (Nhut et al. 2006).
