Abstract

This study provides a comparative analysis of the physiological and anatomical characteristics of leaves in sweet potatoes grown using different cultivation methods during their early growth period. Vegetative indices such as normalized difference vegetation index (NDVI) and carotenoid reflectance index 1 (CRI1) were significantly affected by the cultivation method, accounting for 60.2% and 54.3% variation, respectively. Key photosynthetic characteristics including soil plant analysis development (SPAD), maximum quantum yield (Fv/Fm), absorption flux per PSII reaction center (ABS/RC), trapped energy flux per PSII reaction center (TR0/RC), and dissipated energy flux per PSII reaction center (DI0/RC) were also influenced by the cultivation method, accounting for 45.3%, 50.1%, 45.0%, 42.1%, and 37.9% variation, respectively. Partial least squares discriminant analysis (PLS-DA) revealed that transplanting decreased NDVI, CRI1, SPAD, and Fv/Fm, suggesting inhibited plant vitality, lower carotenoid content for stress defense, and less efficient photosynthesis. Conversely, transplanting increased ABS/RC, TR0/RC, and DI0/RC. This indicates that while their reaction centers absorbed more light energy, a significant portion was inefficiently dissipated as heat. While, transplanting formed well-developed leaf anatomical structures, including thick midribs and wide vascular bundles and xylem diameters.
