Controlled Temperature Treatments Affect Holy Basil's Growth, Compounds, and Aroma

Research has demonstrated that preharvest temperature treatments can significantly impact the physiological characteristics, secondary metabolites, and volatile compounds of holy basil (Ocimum tenuiflorum). These findings were observed under controlled environmental conditions, suggesting a direct link between temperature exposure before harvest and the plant's overall quality. The study focused on how varying temperatures influence the plant's biochemical makeup, including compounds that contribute to its medicinal properties and distinct aroma. Specifically, the research explored changes in physiological traits, which could relate to growth rate, stress response, or overall plant health. Furthermore, the analysis extended to secondary metabolites, a diverse group of organic compounds that plants produce but are not directly involved in their basic survival functions, often possessing therapeutic or aromatic qualities. The volatile compounds, responsible for the plant's scent, were also examined, indicating potential alterations in its olfactory profile. These controlled experiments provide valuable insights for agricultural practices aimed at optimizing holy basil production for specific applications, whether for medicinal use, culinary purposes, or the fragrance industry. The findings highlight the importance of precise temperature management during the critical preharvest phase to achieve desired outcomes in holy basil cultivation.
