Micropropagation and phytopathology of calla lily (Zantedeschia spp.)

Abstract

Calla lily (Zantedeschia spp.) is an herbaceous flowering plant that belongs to the Araceae family, with worldwide distribution. Native to the swampy or mountainous regions of South Africa, it is valued as an ornamental plant due to its extraordinary spathe and decorative leaves. However, its production has decreased due to the presence of diseases. In vitro culture of plant cells and tissues has been successfully applied to precisely diagnose and control diseases to produce disease-free plants. This study analyzes information from in vitro techniques applied to this crop, highlighting phytopathological aspects. It considers the different stages of in vitro culture and the process of obtaining and propagating healthy or pathogen-free plants. In vitro culture has proven to be an effective tool for rapid clonal propagation and multiplication of Zantedeschia spp. Sanitary management before the in vitro culture is recommended.
