The application of DCPTA to mung beans significantly enhances photosynthetic carbon metabolic capacity, increases the number of pods and grains per plant, and consequently boosts yield. Studies indicate that foliar spraying with DCPTA at a concentration of 40 mg/L during the initial flowering stage effectively improves plant morphological parameters; Зокрема, площа листя, вміст хлорофілу та швидкість фотосинтезу демонструють значне збільшення (p <0,05).
This treatment promotes sucrose synthesis and translocation—and strengthens the coordination of source-sink relationships—by upregulating the activity of enzymes involved in carbon metabolic pathways, thereby directing a greater proportion of photosynthetic products toward the pods and grains. Concurrently, DCPTA enhances the activity of antioxidant enzymes—such as SOD, POD, and CAT—to alleviate abiotic stress, thereby facilitating the healthy growth and development of the plants.
Furthermore, the glucose metabolism of mung beans responds favorably to DCPTA, with the activation of multiple key genes associated with sugar metabolism and energy conversion, which further substantiates its role in regulating yield formation.
