| 摘要: |
| 以成熟饱满的美味猕猴桃种子发芽获得实生苗,分别以实生苗的茎段、叶柄和叶片为材料建立了再生体系。结果表明:种子以2.5 mg/L的赤霉素(GA3)处理8 h较适合; 以培养基发芽较为适合; 茎段、叶柄和叶片的愈伤组织的诱导率均为100%,且茎段、叶柄比叶片容易脱分化,但叶片的平均出苗率最高。再生苗在移栽5d后,开始长出新叶,10 d后就能完全适应外界环境。 |

| Abstract: |
| The full and mature seeds of kiwifruit were germinated to obtain the seedlings,and the regeneration system was established by using the stems,petioles and leaves as explants. The results showed that:the concentration of GA3 which was appropriate to treat the seeds was 2.5 mg/L and the treatment time was 8 h; the medium was more suitable for seed germination; the stems and petioles was easier to dedifferentiation than leaves,however,the average emergence rate of leaves was the highest. |
| Key words: kiwifruit seedling explants regeneration system |
