Ushbu ilmiy maqolada Xorazm viloyatining tuproq-iqlim sharoitida introduksiya qilingan dorivor o‘tkir bargli sano (Cassia acutifolia Del.) va tor bargli sano (Cassia angustifolia Vahl.) turlarining agrobiologik, o‘sish va rivojlanish dinamikasi, suv rejimi hamda barg tarkibidagi biologik faol moddalar (flavonoidlar, fenolik birikmalar, antraglikozidlar) miqdori qiyosiy o‘rganilgan. Tadqiqotlar natijasida, Cassia angustifolia turi yuqori o‘sish sur'ati, vegetativ biomassa to‘plashi va reproduktiv salohiyati bilan ajralib tursa, Cassia acutifolia turi yuqori darajadagi suv saqlash qobiliyati (82,6 %) va past suv tanqisligi (11,8 %) hisobiga qurg‘oqchilik va yuqori haroratga nisbatan kuchli fiziologik moslashuvchanlikni namoyon etdi. Biokimyoviy tahlillar o‘tkir bargli sano bargida antraglikozidlar (2,84 %), flavonoidlar (3,86 %) va fenolik birikmalar (5,72 %) miqdori tor bargli sanoga nisbatan yuqori ekanligini ko‘rsatdi. Olingan ma'lumotlar mahalliy farmatsevtika sanoatini sifatli dorivor xomashyo bilan ta'minlashda muhim amaliy asos bo‘lib xizmat qiladi.

Listening comprehension occupies a central position in foreign language learning and serves as a foundation for the development of communicative competence. In English as a Foreign Language (EFL) contexts, listening is often considered one of the most challenging skills because learners must process spoken language in real time while simultaneously interpreting meaning, context, and speaker intention. Effective listening comprehension involves a complex interaction of cognitive, linguistic, and contextual factors. This article explores the nature of listening comprehension in EFL, examines its theoretical foundations, discusses the major factors influencing listening performance, and highlights its significance in language acquisition. The study emphasizes the importance of adopting appropriate instructional strategies to improve learners’ listening abilities and overall language proficiency.
