In the present work it is demonstrated that Salicylic acid (SA) and Methyl Jasmonate (MeJA) provided protection of photosynthesis (A) against paraquat (Pq) stress and diminished the oxidative damage caused by Pq. Barley seedlings (12d old) were supplied with 500 μM SA, 23 μM MeJA or 10 μM Pq via the transpiration stream and kept in the dark for 24 h. They were then exposed to 100 μmol.m–2.s–1 PAR and samples were taken 1, 2, 3, and 6 h after the light exposure. Leaf gas exchange parameters, the… CONTINUE READING
