摘要: 为了解决软枣猕猴桃[Actinidia arguta (Sieb. & Zucc) Planch. ex Miq.]初代培养中外植体诱导率低且快繁效果差的难题,以软枣猕猴桃展叶为外植体,采用不同消毒试剂及消毒处理时间,筛选出最佳的灭菌程序;将不同培养基与不同浓度的KT、2,4-D组合,筛选出最佳的初代培养培养基配方。结果表明,选用展叶为外植体,75% CH3CH2OH处理30 s后10% NaClO处理20 min,0.1% HgCl2处理10 min后去离子水冲洗3~4次,接至MS+0.4 mg/L 2,4-D+1 mg/L KT+3%白糖+0.55%琼脂,pH 5.8的培养基上,置于光照2 500 lx、8 h/d,26 ℃下培养8 d后有少部分愈伤组织出现,60 d后平均单芽愈伤组织可达0.8 g以上,平均单个愈伤组织长度在0.7~1.4 cm,属中块愈伤组织。

Abstract: In order to solve the problem of low induction rate and poor rapid propagation effect of explants in the primary culture of Actinidia arguta (Sieb. & Zucc) Planch. ex Miq., the leaves of Actinidia arguta were used as explants, and the optimal sterilization procedure was selected by using different disinfection reagents and disinfection treatment time. Different mediums and different concentrations of KT, 2,4-D were combined to select the best initial culture medium formula. The results showed that the expanded leaves were selected as explants, treated with 75% CH3CH2OH for 30 s, then treated with 10% NaClO for 20 min, and treated with 0.1% HgCl2 for 10 min. The explants were rinsed with sterile water for 3~4 times, and then transferred to the medium MS+0.5 mg/L 2,4-D+1.0 mg/L KT+3.00% sugar+0.55% agar, pH 5.8. The medium was placed in light of 2 500 lx, 8 h/d, and cultured at 26 ℃ for 8 d. A small number of callus appeared, and the average single-bud more than 0.8 g after 60 d. The average length of single callus was 0.7~1.4 cm, belonging to medium callus.
