Combined effects of prohexadione‐calcium and growing environment on sweet cherry fruit quality and postharvest performance

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Sweet cherry (Prunus avium L.) is a high‐value fruit crop, but its commercial success is often limited by poor pigmentation, reduced firmness, and short shelf life. This study evaluated the effects of preharvest applications of prohexadione‐calcium (1.5 L ha−1) on fruit quality and storage performance in lowland and hilly orchards ...

Exploration of the Phytochemical and Antidiabetic Properties of Teucrium polium: A Natural Asset for Type 2 Diabetes Management

ChemistryOpen, EarlyView.
Teucrium polium shows antidiabetic activity with its phytochemical composition and biological activities. The essential oil is rich in carvacrol, thymol, γ‐terpinene, and o‐cymene, while the aqueous and hydroethanolic extracts are characterized by poliumoside, verbascoside, isorhamnetin‐3‐O‐rutinoside, and apigenin‐7‐rutinoside. Antioxidant activity is
