Phenotypes of two rice cultivars. (a) Phenotypes of YN and YB at 30 DAF. YN is shown on the left, and YB in shown on the right. (b) Phenotypes of flag leaves of YN and YB plants at different stages after flowering. Bars = 5 cm. (c) SPAD values and chlorophyll contents of flag leaves of YN and YB plants after flowering. The values are the means ± SDs of 3 measurements. FW fresh weight. (d) Detached flag leaves from YN and YB plants at the flowering stage were incubated in water for 5 days in darkness. (e) DAB staining of flag leaves of YN and YB at 30 DAF. (f) Relative expression of RCCR1, NOL, NYC3, OsNAP, Osh36 and OsI57 in YN and YB flag leaves at different stages after flowering. The values are the means ± SDs of 3 repeats.
