诱变

The main results were as follows: 1.After being radiated with 60 Co-γ, seven types of mutated plants were obtained through morphologic observation on the aftergrowth of the regeneration plantlets. The mutation characters included the purple leaf vein and petiole, the spotted leaf, the strumae leaf, the acerose leaf, the tender stem, the leaf shape variation, and the leaf color variation.
