摘要: 为建立番茄胚性愈伤组织繁殖体系,将番茄合子胚接种于不同培养基上进行胚性愈伤组织的诱导,并将诱导出的胚性愈伤组织转接到含有不同激素的MS培养基上进行增殖培养。试验结果显示,在MS+5.0 mg/L BA+3.0 mg/L 2,4-D+0.5 mg/L NAA+60 g/L蔗糖培养基上可直接诱导出胚性愈伤组织;在MS+2.0 mg/L BA+0.5 mg/L 2,4-D+30 g/L蔗糖的培养基上愈伤组织胚性化保持效果最好,生长速度最快。本试验研究结果对番茄人工种子的研制具有一定的参考价值。

Abstract: In order to establish the propagation system of tomato embryogenic callus, the embryogenic callus was induced by inoculating tomato seed embryo on different media, and the induced embryogenic callus was transferred to MS media containing different hormones for propagation culture. The results showed that embryogenic callus could be induced directly on MS+ 5.0 mg/L BA+ 3.0 mg/L 2,4-D+ 0.5 mg/L NAA medium containing 6% sucrose, and embryogenic callus could be maintained best and grew fastest on MS+2.0 mg/L BA+ 0.5 mg/L 2,4-D+30 g/L sucrose medium. The results of this experiment have certain reference value for the development of tomato artificial seeds.

Key words: tomato, embryogenic callus, zygotid embryo, artificial seed
