Carbohydrate dynamics in rice leaves under shading stress (Purnendu, Swarnaprabha, IR64, IR8) during Kharif 2022 and 2023 under normal light (NL) and simulated low light (LL). (a) Total carbon content (TC) across flag (FL), second (2L), third (3L), and fourth (4L) leaves. (b) Total soluble sugars content (TSS) and (c) Leaf starch content in FL estimated at 6:00, 9:00, 11:00, and 17:30 h. Data are means ± SE (n = 6). Asterisks indicate significance by t-test (*P < 0.05, **P < 0.01, ***P < 0.001); ns = not significant.
