Phenotypic characterization of the pgl mutant. (A) B73 and pgl were observed at different stages. V6, sixth leaf stage; V8, eighth leaf stage; V10, tenth leaf stage. (B) Pigment contents of the third leaf were measured in B73 and pgl using absorption photometry. Seedlings were grown to the third-leaf stage in greenhouse. Data are presented as the means ± SD (n = 3). (C) Relative chlorophyll content was measured and compared at different stages between B73 and pgl. V15, fifteenth leaf stage; V16, sixteenth leaf stage; R2, blister stage; R3, milk stage; R4, dough stage; R5, dent stage; R6, physiological maturity stage. Data are presented as the means ± SD (n = 9). Asterisks represent significant differences between B73 and pgl detected by independent sample T test (*P < 0.05; **P < 0.01).
