Figure 2. Histological analysis of the aboveground parts of sd37 and 3037.

Figure 2

(A) The seedling phenotypes of sd37 and 3037 plants at 7 DAG. Arrows indicate the second leaf sheath. Bar  =  1 cm. (B) Parenchyma cells in the second leaf sheaths of sd37 and 3037 plants. Bars  =  0.05 mm. (C) The number of parenchyma cells in the second leaf sheaths of sd37 and 3037 plants. Error bars indicate ± SD (N = 20). A significant difference (**, P<0.01) was found between the sd37 and 3037 plants. (D) The length of parenchyma cells in the second leaf sheaths of sd37 and 3037 plants. Error bars indicate ± SD (N = 20). A significant difference (*, P<0.05) was found between the sd37 and 3037 plants. (E) Longitudinal sections through each stem internode of sd37 and 3037 plants. Arrows indicate the second internodes below the panicle. Bar  =  1 cm. (F) Longitudinal sections of the middle of the second stem internode of sd37 and 3037 plants at the heading stage. Bars  =  0.05 mm. (G) The length of the second stem internodes in sd37 and 3037 plants. Error bars indicate ± SD (N = 20). A significant difference (**, P<0.01) was found between the sd37 and 3037 plants. (H) The length of the parenchyma cells in the second internodes in sd37 and 3037 plants. Error bars indicate ± SD (N = 20). No significant difference (P>0.05) was found between the sd37 and 3037 plants. (I)–(J) Longitudinal sections through the SAMs of 3037 and sd37 plants. Arrows indicate the second internode. Bars  =  0.05 mm. (K) Longitudinal cell number in the second internode below the SAM. Error bars indicate ± SD (N = 10). A significant difference (**, P<0.01) was found between the sd37 and 3037 plants.
