Effect of Pi deficiency on the shoot and root of two wheat cultivars. a Shoot fresh weight (FW), b root FW, and c R/S ratio (FW). Twelve-day-old wheat seedlings were grown on Pi-sufficient (+Pi, white bars) or Pi-deficient (−Pi, black bars) solution for 7 days. Data are means ± SD (n = 4). Different lowercase letters indicate significant differences at p < 0.05 among columns using the least significant difference multiple range test
