Abstract Wheat (Triticum aestivum L.) is an important cereal crop cultivated in the most economically developed coutries. The elaboration of new effective growth regulators for intensification of seed germination stage and vegetative growth of wheat is an actual problem for modern agriculture. In our work the comparative analysis of regulating activity of low molecular weight heterocyclic compounds, derivatives of [1,3]oxazolo[5,4-d]pyrimidine and N-sulfonyl substituted of 1,3-oxazole, and plant hormones auxins IAA (1H-Indol-3-ylacetic acid) and NAA (1-Naphthylacetic acid) on acceleration of vegetative stage of wheat (Triticum aestivum L.) cultivar Zimoyarka was conducted. The growth parameters of roots and shoots of the 20th-day-old wheat seedlings grown on the water solution of the chemical heterocyclic compounds used at the concentration 10-9M were similar or higher of the growth parameters of roots and shoots of the wheat seedlings grown on the distilled water (control) or water solution of auxins IAA and NAA used at the same concentration 10-9M. The obtained results confirmed the high auxin-like stimulating effect of derivatives of [1,3]oxazolo[5,4-d]pyrimidine and N-sulfonyl substituted of 1,3-oxazole on growth of wheat (Triticum aestivum L.) cultivar Zimoyarka during vegetative stage.
Keywords Triticum aestivum L., [1,3]oxazolo[5,4-d]pyrimidine, N-sulfonyl substituted of 1,3-oxazole, IAA, NAA.
