Abstract

Enshi is a high-incidence area for Plasmodiophora brassicae infection in Brassica rapa in China; however, the differential immunomodulatory effects of selenite (Se\(^{4+}\)) on the infection of Brassica rapa by the Plasmodiophora brassicae (Pb) remain unclear. In this study, Enshi Gaoshan Brassica rapa (GBr) was selected. Pre-treatment with 0–10 mg/L Se\(^{4+}\) was applied, followed by artificial inoculation with Plasmodiophora brassicae spores (8×10\(^9\) spore/mL). Growth characteristics, photosynthesis, and electrophysiological and nutritional metabolic features of GBr leaves were measured. The results indicate that electrophysiological techniques provide more significant distinctions. S2 (1.25 mg/L Se\(^{4+}\)) was identified as the optimal immune concentration. Compared to the CK, S2 exhibited a 1.2 fold increase in \(\Delta G_r\), a 19.5 fold increase in \(\Delta G_z\), and a 2.5 fold increase in Metabolic activity (MA). S4 (5 mg/L Se\(^{4+}\)) was the immune compensation concentration; compared to CK, S4 exhibited increased WRT (1.4 fold), Nutrient active translocation capacity (NAC) (1.9 fold), and \(\Delta G\) (4 fold), achieving immune compensation. Therefore, electrophysiological indicators (\(\Delta G_r\), \(\Delta G_z\), MA, WRT, NAC) showed 30%–50% higher sensitivity than traditional photosynthetic parameters, highlighting the advantages of electrophysiological methods for early, non-destructive monitoring. This study provides innovative smart agricultural technical support for elucidating the immunity of differential Se\(^{4+}\).

The results indicate that electrophysiological techniques provide more significant distinctions. S2 (1.25 mg/L Se\(^{4+}\)) was identified as the optimal immune concentration.
