Study of Abies somatic embryogenesis and its application

Abstract

This paper provides results of somatic embryogenesis study in our laboratory. General description of somatic embryogenesis (SE) induction, maturation of somatic embryos and plantlets regeneration of the Abies species, followed by a comparisons of some characteristics of zygotic and somatic embryos, seedlings and emblings (somatic seedlings). Own results are supplemented with some literature data. Also aplication of SE for improving of plantlet regeneration of elite fir trees from Dobroč primeval is described as well as initiation of the SE from seeds of incompatible crossings of firs where zygotic embryos abort usually several weeks after pollination.

Evaluation of a New Temporary Immersion Bioreactor System for Micropropagation of Cultivars of Eucalyptus, Birch and Fir

“…SE plant propagation is applied in key conifer species utilized for commercial forestry production [7] as well as the production of Christmas trees (e.g., A. nordmanniana) [8][9][10]. The aim of this study was to evaluate a new TIB previously developed and successfully applied for Norway spruce somatic embryogenesis [2] for applicability in shoot multiplication of selected hardwood species A. nordmanniana, E. grandis x E. urophylla, B. pubescens Ehrh, and B. pendula var.…”
