- 1Field A: normal irrigation condition; Field B: normal irrigation condition in reclaimed region; Field C: high salinity condition in reclaimed region. Field locations are described in the “Materials and Methods” section
- 2Data represent the mean of five measurements. DAT: days after transplanting; n.a.: not applicable (all plants dead)
- 3Data represent mean ± standard error (SE; n = 5). Asterisks indicate statistically significant differences between CSA and CSA-Pi9 in each field (*P < 0.05, **P < 0.01, ***P < 0.001; Student's t-test). n.a.: not applicable (all plants died); n.d.: no data
- 4All values in this column represent grain yield per plant, estimated in grams (mean ± SE; n = 5; *P < 0.05; Student's t-test), except CSA-Pi9 in field C, which was harvested in bulk and total grain weight (334 g) was divided into the number of bulked plant (18 plants). This is the reason that there is no standard error in value of CSA-Pi9 in Field C
