Abstract

A standard method for in vitro propagation of late flushing Quercus robur L was developed. Shoot induction on zygotic embryos as well as somatic embryogenesis was induced by a selective use of growth regulators. Shoot formation on zygotic embryos was induced by using modified WPM supplemented with 1 muM BAP + 1 muM 2,4-D and by using modified WPM supplemented with 10 muM BAP. The use of modified WPM supplemented with 10 muM BAP led to an induction rate of 87,9%. In combination with 5 muM 2,4-D shoot formation was already suppressed. The tested hormone combinations of 2,4-D and BAP induced somatic embryos on cotyledons of zygotic embryos, however the induction rates differed strongly. The highest induction rate of 34,8% was achieved on modified WPM supplemented with 1 muM BAP + 1 muM 2,4-D. A total of 36 genotypes were established by shoot formation on zygotic embryos and 17 genotypes were established by somatic embryogenesis. Plant regeneration from somatic embryoswas achieved with 7 of 17 genotypes.
