Table 1 Parameters in light response curves when cotton leaves were covered in dust (light, medium, and heavy) or the control

From: Similar effects as shade tolerance induced by dust accumulation and size penetration of particulates on cotton leaves

Treatments Control Light Medium Heavy
LSP (μmol m− 2 s− 1) 228.06 ± 14a 271.09 ± 36a 366.18 ± 23b 396.07 ± 33b
LCP (μmol m− 2 s− 1) 11.70 ± 0.41a 13.10 ± 1.79a 14.38 ± 1.04a 22.29 ± 1.44b
PNmax (μmol CO2 m− 2 s− 1) 8.47 ± 0.59a 8.27 ± 1.44a 8.96 ± 0.72a 4.68 ± 0.66b
  1. PNmax light-saturated net photosynthetic rate, LSP light saturation point, LCP light compensation point. Values are shown as the mean ± standard error (n = 4 or 5). The different letters in superscripts indicate significant differences among treatments at 0.05% level
