以 PES 液体培养基、固体培养基,采用正交设计,开展了长心卡帕藻(Kappaphycus alvarezii )棕色藻株组织培养和愈伤组织诱导实验,探索了蔗糖、光强、植物生长调节剂对新芽形成和愈伤组织形成的影响,结果表明,固体培养基、IBA、6-BA 处理可诱导该藻产生愈伤组织,同时固体培养基更利于诱导形成愈伤组织;显微跟踪观察显示,该藻愈伤组织与高等植物的疏松愈伤组织不同,由细丝状细胞组成,系藻枝段中心髓部细胞脱分化形成的致密型愈伤组织;另外,愈伤枝段比新芽枝段有更高的光合和呼吸速率。

The brown morphotype of red seaweed Kappaphycus alvarezii collected from Li’an Bay in Lingshui County,Hainan Province of China,was used as explants in order to generate new buds and induce callus.Effect of the PES (Provasoli enriched seawater)media (with or without gelling agent),light intensity,and phytoregulators (Indole-3-acetic acid (IAA),Indole-3-butyric acid (IBA),6-benzylaminopurine (6-BA))were tested on new bud generation and callus formation by orthogonality experiment.The callus forming was observed in microscope,and the changes of the respiration rate and photosynthesis rate in explants among callus forming were detected.The callus of Kappaphycus alvarezii was achieved successfully by the combination of PES solid medium (0.8% ager), IBA,6-BA,while callus was not observed in the combination of PES liqiud medium,IBA and 6-BA.That indicates the solid medium plays an important role in callus induction.Kappaphycus alvarezii callus which consists of com-pact filamentous cells was different from the loose callus of superior plants.And callus derived from the medullary cells.It was found that both photosynthetic rate and respiratory rate in the branch inducing callus were higher than ones of the branch germinating new bud by means of oxygen electrode.
