ОЦЕНКА ПОКАЗАТЕЛЕЙ ФОТОСИНТЕТИЧЕСКОЙ ДЕЯТЕЛЬНОСТИ ПОСЕВОВ TRITITRIGIA CZICZINII TZVEL. В УСЛОВИЯХ МОСКОВСКОЙ ОБЛАСТИ

Abstract

The study of the photosynthetic activity of crops allows us to more fully characterize the agricultural crop and identify signs that can later be used in the breeding of this crop and obtaining highly productive varieties. The research was conducted in the conditions of the Moscow region in 2021-2022. The objects of research were the variety of a new synthetic culture of trititrigia - Pamyati Lyubimovoy, the line of trititrigia M12 and the variety of winter wheat Rubezhnaya. In 2021, the line № 3202 had the maximum leaf area (23.2±4.4 thousand m2/ha), and the Pamyati Lyubimovoy had the maximum value of photosynthetic potential (366.5±19.5 (thousand m2 x day)/ha). The highest biological yield capacity of trititrigia was 506.4±52.7 g/m2 (M12), while the biological yield capacity of Rubezhnaya was 722.9±106.8 g/m2. In 2022, the largest leaf area and photosynthetic potential were noted on trititrigia of Pamyati Lyubimovoy variety (48.81±6.1 thousand m2/ha, 754.5±133.4 (thousand m2 x day)/ha, respectively). The greatest biological yield capacity of trititrigia was observed in the Pamyati Lyubimovoy variety (693.1 ± 29.7 g/m2). Biological yield capacity of winter wheat Rubezhnaya reached 1056.9 ±69.5 g/m2. Thus, the morphological and biological features of trititrigia are largely reflected in photosynthetic indicators and differ from photosynthetic processes occurring in winter wheat crops.
