Foliar nitrogen supply enhances the recovery of photosynthetic performance of cold-stressed coffee (Coffea arabica L.) seedlings
Cold-stressed leaves possess an elevated risk of photodamage due to an inefficient photosynthetic apparatus during winter conditions. Recovery of cold-stressed coffee seedlings treated with different concentrations of nitrogen applied as foliar urea sprays [control (0), 5, 10, 20, and 40 mM], was in...
