Figure 2From: Morphological, cytological and metabolic consequences of autopolyploidization in Hylocereus (Cactaceae) speciesMorphology of fruit, seed, and embryo tissues in the donor and autopolyploid lines. A–D, Mature fruits of diploid H. monacanthus (A), autotetraploid line D-27 (B), allotriploid S-75 (C), and autohexaploid line D-2.3 (D). E–H, Black seed separated from the pulp of diploid H. monacanthus (E), autotetraploid line D-27 (F), allotriploid S-75 (G), and autohexaploid line D-2.3 (H). I–L, Embryo removed from black coat seeds of diploid H. monacanthus (I), autotetraploid line D-27 (J), allotriploid S-75 (K), and autohexaploid line D-2.3 (L).Back to article page
