- 摘要:
- 以 8 个菜用大豆品种的未成熟子叶为外植体,在 MS(附加高浓度 2, 4 - D)培养基诱导愈伤组织形成、体细胞胚胎发生与再生植株。结果表明 :八个菜用大豆品种的未成熟子叶均可诱导产生愈伤组织与体细胞胚胎发生, 出愈率为 14. 71%~ 100%。体细胞胚胎发生率变化在 0~ 36. 76%之间,绿子叶菜用大豆没有形成体细胞胚。体细胞胚可正常萌发产生小植株 ,移栽成活结实 。菜用大豆的出愈率和体细胞胚胎发生率与基因型有关。
- Abstract:
- Callus formation, somatic embryogenesis and plant regeneration were induced by MS medium in-cluding higher concentrations of 2 ,4- D with immature cotyledon of eight genotypes in vegetable soybean.The results showed that callus formation and somatic embryogenesis of eight genotypes of vegetable soy-bean with immature cotyledon were induced successfully. Frequencies of callus formation varied from14. 7 %to 100%and frequencies of somatic embryogenesis changed 0 ~ 36. 76%. Somatic embryo has notbeen induced from variety Luziyecaidou with green cotyledon. Somatic embryos could germinate , regener-ate plantlets and seed. The frequencies of callus and somatic embryogenesis were associated with genotypesin vegetable soybean.
