Abstract
The seed morphology of 22 taxa (12 genera) of Solanaceae in Korea was studied by stereo and scanning electron microscopy, and a detailed description of seed morphological features for all examined taxa is provided. The color of the seed is yellow to black, and the shape is reniform to circular. Its size is 0.56-4.29 mm in length and 0.38-3.20 mm in width. The largest sample was found in Datural metel, while the smallest was in Petunia hybrida. Three different surface types (verrucate, verrucate-reticulate, and reticulate) were recognized in the studied taxa. The top of the anticlinal wall produces appendages known as 'fibrils'. This projection of anticlinal wall was found to be specific to the genus Solanum (S. japonense, S. lyratum, and S. lycopersicum). The morphological features (seed shape, size, color, hilum shape, surface type, and fibrils) of the family Solanaceae in Korea are described and their systematic implications are briefly discussed.
