- 摘要:
- 以软枣猕猴桃休眠枝条与当年生新梢茎段为试材,采用单因素试验方法,以期通过对软枣猕猴桃枝条外植体及其芽进行严格灭菌,确保利用软枣猕猴桃休眠芽及新梢腋芽进行超低温保存后复苏的成活率。结果表明:休眠期单芽茎段以去皮后再采用0.1% HgCl2灭菌30 min为宜;当年生新梢单芽茎段以采用0.1% HgCl2灭菌10 min为宜。
- Abstract:
- Dormant branches and the one-year-old stem segments of Actinidia argutawere taken as the test materials,a single factor test method was used to strictly sterilize the explants and buds of Actinidia arguta to ensure the survival rate of dormant buds and new shoots after cryopreservation.The results showed that the single-bud stem segment in the dormant period was sterilized by 0.1% HgCl2 for 30 minutes after peeling;the single-bud stem segment of the new shoot was sterilized by 0.1% HgCl2 for 10 minutes.
