桉树,约占世界人工林的五分之一,其木材产量,已成为世界木材产量最多的三个树种之一,广泛用于纤维工业。为使桉树苗快速繁育,国内外正开展桉树组织培养的试验研究。不少实验室已从器官及组织培养,分化出完整植株,但尚未见诱导出胚状体的报道。我所从雷林一号桉树(Eucalyptus“leichow”“No:1”)46号、9号优树种 Eucalyptus, accounting for about one-fifth of the world’s plantations, its timber output has become one of the three tree species with the highest timber production in the world and is widely used in the fiber industry. Eucalyptus seedlings for rapid breeding, both at home and abroad are conducting eucalyptus tissue culture experimental study. Many laboratories have been cultured from organs and tissues and differentiated into complete plants, but no reports of embryoid bodies have been reported yet.
