Light response curve
Light response curves of photosynthesis of six-week old VC and transgenic plants, grown under 10h L/14h D, in soil, were measured usingi nfrar ed g as a nalyser, IRGA (LiCor 6400XT), with 6400-18A RGB (Red, Green, Blue) light source at different light intensities. Sample chamber CO2 concentration was maintained at 400 μmol mol-1. The air temperature in the sample chamber was maintained at 25°C, and the relative humidity at 60%.
