Influence of nitrogen deficiency on photosynthesis and chloroplast ultrastructure of pepper plants (Research Note)
Pepper plants (Capsicum annuum L.cv.Zlaten Medal) were grown on nutrient solution without nitrogen, and photosynthetic response of plants was examined by determination of leaf CO2 fixation and chlorophyll and carotenoid contents.The absence of nitrogen in the medium resulted in a decrease of the leaf area and of plant biomass accumulation, and in a
