Manganese (Mn) excess is a major abiotic stress for plant growth. In the present study, we investigated effects of Mn on photosynthesis in Ligustrum lucidum and Melia azedarach leaves using chlorophyll fluorescence transients. Both species were exposed to two concentrations (0.5 1 mmol) 10 30 d. Results showed that significantly inhibited photosynthesis. With increase concentration time, inhibi...
