Figure 1From: Morphological, cytological and metabolic consequences of autopolyploidization in Hylocereus (Cactaceae) speciesStomatal density and size, sporad shapes, and pollen stainability in the donor and autopolyploid lines. A–D, Stomatal density and size of diploid H. monacanthus (A), autotetraploid line D-27 (B), allotriploid S-75 (C), and autohexaploid line D-2.3 (D). E–H, Sporad shapes in the autohexaploid line D-2.3, monad (E), triads (F), tetrads (G), and polyads (H). I–L, Pollen stainability of diploid H. monacanthus (I), autotetraploid line D-27 (J), allotriploid S-75 (K), and autohexaploid line D-2.3 (L). Arrow indicates an aborted pollen grain.Back to article page
