摘要

Haploid oat embryos obtained by distant crossing of oat (Avena sativa L.) with maize (Zea mays L.) are morphologically diverse. Since large haploid oat embryos convert into plants more easily, the aim of our research was to investigate anatomical and metabolic differences between large (≥ 1.5 mm) and small (< 1.5 mm) haploid embryos of hulled ‘Krezus’ and hulless ‘Akt’ oat cultivars. Anatomical sections of the embryos were compared with the profile of phytohormones, amino acids, phenolic acids, polyamines, and sugars determined by HPLC. We noticed that the development rate of haploid oat embryos depends on the genotype, as 21-day-old ‘Krezus’ embryos were characterized by a more advanced anatomical structure compared to ‘Akt’ embryos. We have shown that small ‘Krezus’ embryos accumulate significant amounts of active phytohormones: auxins, cytokinins, gibberellins, as well as amino acids: tryptophan, phenylalanine, methionine; phenolic acids: cinnamic, ferulic, sinapinic, chlorogenic, and polyamines: spermidine and spermine. These metabolites, remaining closely interdependent, guarantee the embryo’s further growth and development.
