Fig. 2From: Comparative transcriptomic analysis of maize ear heterosis during the inflorescence meristem differentiation stageInflorescence meristem size in hybrids and inbred lines. A Scanning electron micrograph of 2–4-mm immature ears from Zheng58×lx9801hlEW2b (HY) and Zheng58×lx9801 (CK), Bar = 200 μm. B Scanning electron micrograph of 2–4-mm immature ears from lx9801, lx9801hlEW2b and Zheng58, Bar = 150 μm. C–D Comparison of inflorescence meristem size between lx9801, lx9801hlEW2b, Zheng58, Zheng58×lx9801hlEW2b and Zheng58×lx9801. * and ** indicate significant differences at the 0.05 and 0.01 probability levels. More than 10 individuals were measured for each inbred line, and 30 individuals were measured for the two hybridsBack to article page
