From: The efficacy of chemical topping in field-grown cotton is mediated by drip irrigation amount in irrigated agricultural area

Fig. 1

The effect of the MCEW on cotton gas exchange parameters under different drip irrigation amounts at different growth stages in 2014. MCEW represents a 25% mepiquat chloride emulsion in water; PF, peak flowering stage; PB, peak boll stage; BO, boll opening stage; MT, MC1, MC2, and MC3 represent manual topping as control, 450, 750, and 1 050 mL·hm−2 MCEW, respectively. Pn, Gs, Ci, and Tr represent the net photosynthetic rate, stomatal conductance, intercellular CO2 concentration, and transpiration rate, respectively. For each stage, bars with different letters are significantly different at P < 0.05
