( Yamori et al., 2012 ; Zhang et al., 2015 ). After 30 min of illumination to obtain steady-state photosynthesis, the net photosynthetic rate in the most newly expanded leaves of 31- to 35-d-old plants grown under W24 was measured under growth light

of the rolling average of photosynthesis calculated by the LI-6400 was less than 2%. Intrinsic water use efficiency ( WUEi ) was calculated from gas exchange measurements as: WUEi = A / g wv , where: A = net photosynthetic rate in μmol CO 2 /m −2
