Abstract: In our work the low molecular weight heterocyclic compounds derivatives of [1,3]oxazolo[5,4-d]pyrimidine and N-sulfonyl substituted of 1,3-oxazole were synthesized. Comparative analysis of plant growth stimulating activity of these heterocyclic compounds and plant hormones auxins IAA and NAA, and cytokinin Kinetin was conducted. It was found that all tested heterocyclic compounds used in concentration 10-9M/l of distilled water revealed high auxin-like growth stimulating activity on the soybean (Glycine max L.) of cultivar Valuta, wheat (Triticum aestivum L.) of cultivar Zimoyarka, and flax (Linum usitatissimum L.) of cultivar Svitanok. The growth parameters of 20th-day-old seedlings of soybean, wheat, and flax grown on the 10-9M water solutions of heterocyclic compounds were as generally similar or higher than the growth parameters of seedlings grown on the water solution of auxins IAA and NAA used in the same concentration as compared to lower growth parameters of control untreated seedlings grown on the distilled water. Specific bioassay on cytokinin-like activity, conducted on the isolated cotyledons of muscat pumpkin (Cucurbita moschata Duch. et Poir.) of cultivar Gilea, showed that all testing heterocyclic compounds used in concentration 10-9M/l of distilled water demonstrated expressive cytokinin-like stimulating effect on the growth of the isolated cotyledons of pumpkin. Obtained data confirm perceptiveness of application derivatives of [1,3]oxazolo[5,4-d]pyrimidine and N-sulfonyl substituted of 1,3-oxazole in the agricultural practice for intensification of growth and development of soybean, wheat, flax and pumpkin plants.
