3.1 Chlorophyll fluorescence parameters
Redroot pigweed’s leachate affected chlorophyll fluorescence parameters
of cucumber and wheat species differently (Table 2). Leachate treatment
significantly increased the F0, Fm,
Fv, NPQ, q0, qA, Rfd,
and SV0 values in cucumber (p ≥0.01). The same
treatment in wheat increased F0, NPQ, and
SV0 and decreased ETR and
Fv/Fm parameters significantly (p≥0.01).
