Abstract
The rice dormant bud is the basis for rice reproduction and regeneration, and it has the potential to develop into a
complete plant. In this study, the rice stems including dormant buds of the last three internodes from different varieties intercepted
after the first season rice harvested were used as the research material. Feasibility and superiority of asexual propagation system was
analyzed based on the difference in various traits and physiological parameters were compared among seedlings derived by, hormone
treatment, non hormone treatment, directly transplanted rice stubble and seeding. The result reveals that rice stems with dormant
buds, regardless of hormone treatment, had significantly higher seedling regeneration efficiency than directly transplanted rice
stubbles which imitate ratooning rice, and it also showed a greatly improve the seedling regeneration rate and increased chlorophyll
content, leaf area, panicle length and grains per panicle in the regenerated seedlings. Hormone treatment slightly improved the
performance of the plants obtained from rice stems
in vitro
than non-hormone treated control, but similar with the plants from seed
