บทคัดย่อ

Cell suspension cultures of rice varieties Khao Dawk Mali 105 and Suphanburi 1 were tested in eight media. Both varieties had successfully established in N6 medium supplemented with 2.0 or 4.0 mg/ l 2,4-D. Rice variety Suphanburi 1 showed higher cell growth rate than variety Khao Dawk Mali 105 while the percentage of cell viability and embryogenic cell were not significantly different. However, the regeneration of plantlets from cell suspension derived-calli of rice variety Khao Dawk Mali 105 was significantly higher (83.3%) than that of variety Suphanburi 1 (67.8%).
