Somatic Embryogenesis in , and ,, and . was also done and hybrid and back-crossed families were made. Genetic variation of glutamate dehydrogenase isozymes of both species was also reported. However, the fact that first fruiting is usually observed only in 30 to 50 year-old trees, indicating that a long time is necessary in the imp

Somatic Embryogenesis and Plant Regeneration in ,,ixed stand with beech (..), fir (.), spruce (.) and pine (., .). A small, native, community of Serbian spruce is also located on a flat, deep, swampy soil, in a mixture with beech, fir, and spruce on Mount Tara, Serbia (.). Recent studies indicate that . can be grown in a much wider ecological range

Somatic Embryogenesis in Slash Pine (, Engelm.), in east Texas where it now seeds naturally (Lohrey & Kossuth, 1990). Plantings outside its natural range mostly occurred over three decades spanning from the early 1950s through the latter 1970s. During this time, the slash pine ecosystem increased by 22% (.).

Somatic Embryogenesis in Maritime Pine (,),on was developed in the early 1960’s. The main criteria for selection are the vigour and the straightness of the stem (.). Conventional methods of selection, breeding and progeny testing of forest trees are useful but very slow. Therefore, it is well known that many difficulties have to be overcome
