| Abstract: | The tubercle on lemma surface of grain in 20 species of Oryzae with electric-scanning microscope were studied. The 5 kinds of tubercles have been classified based on the characters of tubercles, which are e. g. "bi-peak" tubercle kind, "multi-peak" tubercle kind, "warty-peak" tubercle kind, "simple-peak" tubercle kind and trace tubercle kind. The "acute" type and "obtuse" type of the bi-peak tubercle kind were classified also based on the peak angle and col angle. The correlation of classification and evolution among Oryza species with the character of tubercle were discussed. |
