The results indicate that plants in the SR at T12 exhibited the highest BC load (bcH) (1.94 × 10 06 ± 8.81 × 10 05 particles·mL −1 ) while plants in the RR at T12 exhibited an intermediate BC load (bcM) (7.26 × 10 05 ± 1.83 × 10 05 particles·mL −1 ), with a highly significant difference compared to the SR at that time point ( p < 0.0001).
