Figure 1From: Reduction of photosynthetic sensitivity in response to abiotic stress in tomato is mediated by a new generation plant activatorPhotosynthetic performance in primed and salt stressed tomato plants. Gas exchange parameters as a percentage (%) of non-NaCl treated control plants were characterised in 30 day old tomato plants from application of NaCl and for eight days subsequently, following priming application of ‘Alethea’ 24 h prior to Day 0, where plants were subjected to a 100 mM salinity treatment. Both Alethea and salinity treatments were then repeated exactly as before 5 d following original treatment days (Day 4 = Alethea, Day 5 = salinity), with plants watered with H2O only on all other days in order to replace transpirational losses. (A) Net photosynthesis, (B) transpiration rate, (C) stomatal conductance, (D) internal CO2 concentration. Asterisks indicate pair-wise significant differences at * P < 0.05, ** P < 0.01, *** P < 0.001. Values are the average of 10 individual plants with standard errors.Back to article page
