| Abstract | Somatic embryogenesis is a promising alternative technique for clonal propagation of superior and genetically engineered forest tree families in coniferous species (Attree and Fowke, 1993; Gupta and Durzan, 1991; Jain et al. 1995). It is also widely considered to be an efficient system for genetic transformation and transgenic plant recovery (Gupta et al. 1988; Wenck et al. 1999). Somatic embryogenesis in conifers was first described relatively by three independent groups: (1) Hakman and von Arnold (1985) achieved plant regeneration through somatic embryogenesis from cultured immature embryos of Picea abies; (2) Chalupa (1985) described somatic embryogenesis and plantlet regeneration from immature and mature embryos of Picea abies; and (3) Nagmani and Bonga (1985) reported the induction of haploid European larch (Larix decidua Mill.) somatic embryos from megagametophytic tissue. Mature conifer somatic embryos produced via plant tissue culture techniques appear to have the same quality as mature zygotic embryos, so somatic embryogenesis is a potential choice and resource for the production of artificial seeds (Attree and Fowke, 1993; Jain et al. 1995). In conifers, plantlet regeneration via somatic embryogensis includes: (1) induction of embryogenic callus; (2) maintance of embryogenic cultures; (3) maturation of somatic embryos; and (4) germination of somatic embryos and plant formation (Tautorus et al. 1991; Jain et al. 1995). Progress on somatic embryogenesis of coniferous woody plants has been reviewed (Attree and Fowke, 1993). However, plant regeneration via somatic embryogenesis from mature zygotic embryos of conifers has been only reported in Picea abies (Jalonen and von Arnold, 1991), Picea glauca (Tremblay, 1990), Picea mariana (Attree et al.1990), Picea pungens (Afele et al.1992), Picea rubens (Harry and Thrope 1991), and Picea sitchensis (Krogstrup 1990). In Pinus, plant regeneration via somatic embryogenesis from mature zygotic embryos of sugar pine (Pinus lambertiana) was reported |
