The teacher of the department, M. Matyaqubov, gave a lecture on the topic of the scientific-methodical seminar on the topic "Using the method of "Lilium flower" in determining the biochemical composition of cereal crops". In the temperate regions of both hemispheres and in the tropics, 2 species grow - N. with a pink nut (N. nicifera) and yellow N. (W. lutea). The leaf is large, shield-shaped, with a long band, floating on the surface of the water or growing above the water. The flower is single, large, bisexual, up to 16 cm in diameter, white or pink, fragrant, opens on the leaf. The fruit is conical, with many nuts, ripens under water. N. propagates from seeds or rhizomes. It blooms in the 3rd year after germination. In India and China, pink N. has been considered a sacred plant since ancient times. There are many cultural forms of N. The stems and leaves of N. contain vitamin C and rubber, and the stems and branches contain a poisonous substance - nelumbin. In the lecture, they gave information about the Nilufar flower and practiced its biochemical composition together with the students. They independently analyze the topic together with their group, ask the teacher about any misunderstandings, and 20 minutes before the end of the lesson, the groups answer questions with each other and are evaluated.
