In the present study, mung bean (Vigna radiata L.) - a salt susceptible and
Indian mustard (Brassica juncea L.) - a salt resistant crop was studied to
find out the differences in stress responses of these crops. Seedlings wer
e grown in water soaked cotton under continuous illumination of 35 mu mole
m(-2) s(-1) at 26 +/- 1 degrees C. Salinity treatment of 0, 0.5 and 1.0% (w
/v) was given to the seedlings at 6 day. Photosynthetic pigment content and
PS II electron transport activity was reduced under salinity in both mung
bean and Indian mustard. The pigment protein pattern of both the crops were
similar. Ratio analysis of B and Q thermoluminescence (TL) glow peaks sugg
ested that S(2)Q(A)- charge recombination was relatively more affected than
S(2/3)Q(B)- charge recombinations.
