STRESSSalt tolerance, ppm NaCl Salt level in ppm NaCl at which the treated plants have less than 50% as much green cover as the control7500  The day before data collection the plants are top-dressed with dry sand to mask any algae growing in the pots. Each flat is photographed from above using a digital camera and a light box. Photoshop is used to crop the image to the edges of the flat and add pink lines marking the edges of the pots. SigmaScan macros are then used to divide the imagie into the 18 individual pots and to calculate the % green cover for each pot. The % cover on each date is adjusted by the % cover for the pot at 0 ppm NaCI, just prior to the beginning of the salt treatment. This compensates for differences in stand caused by variable seed germination. The final green cover is the mean treatment value as percent of the mean control value on that date. Expressing the cover as a percent of the control permits comparison between species that differ in growth habit. ">GRASS.SALT.TOLERANCE.2010.BROWNPI 206274 84i SD
