Seed propagation and seed anatomy of three Eucomis species

I.M. Makena, B. Matsiliza-Mlathi, R. Kleynhans
The genus Eucomis (Hyacinthaceae) includes some of the most commonly used South African medicinal plants and contains species with ornamental potential. The development of a rapid, large scale propagation system for Eucomis has become a necessity in order to ensure a sustainable supply of plant material. However, the main production challenges with Eucomis species are a failure to germinate and slow propagation rates which have been linked to anatomical and environmental factors. Anatomically the seed used, presented a typical pattern of seeds of the Hyacinthaceae family. All three species exhibited similar seed structures with a seed coat consisting of four layers. The temperature had a significant effect on the seed germination and seedling emergence of the species studied. The highest germination percentage was observed in E. comosa (87%). The seedling emergence percentage was the highest in E. autumnalis (80%) at 20°C. The germination and emergence were inhibited at 10°C for all species and reduced at 30°C. The growth medium used affected the emergence and growth of Eucomis seedlings.
