Table 2. Fundamental parameters of the O-J-I-P fluorescence induction curves recorded on attached leaves of Col-0, Ws-4 and Ler-0 accessions.

Parameter Col-0 Ws-4 Ler-0
F v/F m 0.805±0.003 0.808±0.012 0.802±0.009
M0 1.650±0.030 1.711±0.044* 1.574±0.151
M0/VJ 3.796±0.064 3.982±0.081* 3.761±0.125

The significant differences are indicated by asterisk (Student's t test P<0.05).

The plants were grown on soil for 15–17 days at an irradiance of 120 µmol photons m−2 s−1. The leaves were adapted to darkness for 15 min before the measurement (n = 20–25).
