摘要: 为了建立芹菜松散型胚性愈伤组织诱导体系并获得体胚发生,采用芹菜不同的外植体在含有2,4-D的培养基上进行愈伤组织诱导和体细胞胚发生的研究。结果表明:芹菜下胚轴为外植体可以诱导出理想的愈伤组织;愈伤组织在MS+0.5 mg/L KT+0.2 mg/L NAA+1.0 mg/L 2,4-D的培养基上生长最快;在MS+0.5 mg/L KT+0.5 mg/L 2,4-D的培养基上可以诱导出松散型愈伤组织;将松散型愈伤组织转接到MS+0.1 mg/L KT+0.5 mg/L 2,4-D培养基上,每15 d继代培养一次,3次后可获得芹菜松散型胚性愈伤组织;将松散型胚性愈伤组织转接到MS+0.25 mg/L KT+0.25 mg/L 2,4-D培养基上,每15 d继代培养一次,3次后可获得芹菜体细胞胚;将体细胞胚转接到1/2MS培养基上,45 d后可获得芹菜再生植株。本试验成功建立芹菜松散型胚性愈伤组织诱导体系及体胚发生并获得再生植株的培养体系,为芹菜体细胞离体诱变育种奠定一定的基础。

Abstract: In order to establish a loose embryogenic callus induction system of Apium graveolens and obtain somatic embryogenesis, different explants of Apium graveolens were used to induce callus and somatic cell embryogenesis on the medium containing 2,4-D. The results showed that the hypocotyl of Apium graveolens as an explant can induce ideal callus tissue; The callus grew fastest on MS+0.5 mg/L KT+0.2 mg/L NAA+1.0 mg/L 2,4-D medium; Loose callus can be induced on MS+0.5 mg/L KT+0.5 mg/L 2,4-D medium; Transfer loose embryogenic callus tissue to MS+0.1 mg/L KT+0.5 mg/L 2,4-D medium, subculture every 15 days, and obtain loose embryogenic callus tissue after 3 subcultures; The loose embryogenic callus was transferred to MS+0.25 mg/L KT+0.25 mg/L 2,4-D medium and subcultured once every 15 days. After subculturing for three times, the Apium graveolens somatic cell embryos were obtained; After somatic embryos were transferred to 1/2MS medium, regenerated plants of Apium graveolens could be obtained after 45 days. This experiment successfully established the induction system of loose embryogenic callus and somatic embryogenesis of Apium graveolens, and obtained regenerated plants, which laid a certain foundation for in vitro mutation breeding of Apium graveolens somatic cell.
