Histology and origin of somatic embryos derived from Anthurium andraeanum linden ex andré lamina

Abstract

Histological analysis of somatic embryos derived from in vitro-grown lamina of Anthurium andraeanumshowed bipolarity with the presence of shoot and root poles connected by procambium. Vascular connections between the explant and somatic embryos were not observed. Storage of proteins, starch and raphides as well as a suspensor-like structure and an epidermis were observed in the somatic embryos. Origin of the somatic embryos was from a proembryonic cell complex or possibly from a single cell by direct embryogenesis. Both modes of somatic embryogenesis arose from the mesophyll.
