Fig. 4From: Maize (Zea mays L.) responses to salt stress in terms of root anatomy, respiration and antioxidative enzyme activityEffect of salt stress on the anatomic traits of salt-tolerant (JNY658) and salt-sensitive (YY7) maize varieties. Bars being annotated with different lowercase letters indicates they are significantly different at P < 0.05.
