Biological activity of a quinazolone-phosphite derivative synthesized from benzaldehyde and acetone as a plant growth stimulator

Abstract

The development of biologically active compounds based on heterocyclic structures remains a promising direction in modern agrochemical research. In this study, a quinazolone–phosphite derivative synthesized from benzaldehyde and acetone was evaluated for its plant growth–stimulating activity. The biological effectiveness of the compound was assessed through standard germination and growth assays, including seed germination rate, root elongation, and biomass accumulation. The results demonstrated a significant enhancement in plant growth parameters compared to untreated controls, indicating the stimulatory potential of the synthesized compound. The presence of the phosphite group is assumed to contribute to improved nutrient assimilation and metabolic activation in plants, while the quinazolone moiety may enhance biological activity through its known bioactive properties. The findings suggest that this compound can be considered a promising candidate for application as an eco-friendly plant growth regulator in sustainable agriculture.
