“…Peroxidase is considered to be the main enzyme responsible for the catabolism of the phytohormone IAA in higher plants (Campa 1991). Our previous studies aimed at biochemistry of embryogenesis somatic end zygotic embryos in silver fir confirmed that mature zygotic embryos have lower specific activity of peroxidase than mature somatic embryos (Kormuťák and Vooková 2005). Woodward and Pearce (1988) studied the effect of variations in naphthalene acetic acid (NAA) and BAP concentrations on inhibition of Ph.…”

Defence reactions of desiccated cotyledonary somatic embryos and mature zygotic embryos of Abies numidica were tested by dual cultures with tester, fungus Phaeolus schweinitzii. Both types of embryos expressed defence reactions. Mutual comparisons of zygotic and somatic embryos showed important differences between defence reactions against mycelial growth towards these embryos. Greater defence reactions were observed in zygotic embryos relative to defence found in somatic embryos.

“…Data of several authors indicate similar or identical storage proteins contents in somatic and zygotic embryos (Klimaszewska et al 2004, Kormuťák andVooková 2005). Marked differences were observed in carbohydrate spectra between developing seeds and maturing somatic embryos of Picea abies (Gösslová et al 2001).…”
