Chl and Car were measured in 80% acetone extracts from the top fully expanded leaves (except the flag leaf) from 4-week-old seedlings or tasseling adults grown in field. Mean and SE values were calculated from five independent determinations. Asterisk indicates significant difference as compared with Zheng58 wild-type at P<0.01 (Student’s t test).
