The average crystallinity of corn starch is higher than that of WT, but the proportion of linear part and branching part between the two phases of typical ae corn starch particles is equal, and the crystallinity distribution is uniform, which means that the ae mutation gene only affects the assembly of blocklet or changes its directional arrangement, thus making the typical ae corn starch present two-phase characteristics. Compared with WT corn starch, the average crystallinity of GEMS-0067 corn starch is increased, which indicates that the joint action of HAM and ae gene increases the non-uniformity of starch particle morphology and enhances the crystallinity of starch, but does not change the uniformity of starch crystallinity, and the crystallinity of the rod-shaped starch particles is still uniformly distributed. The average crystallinity WT of wx ae starch granules is high, and the crystallinity distribution inside the granules is uniform, indicating that the interaction of wx and ae genes enhances the crystallinity of starch granules, without changing the proportion of linear and branching parts.

ae du淀粉结晶程度为五种淀粉中的一种,说明du基因的引入降低了淀粉颗粒结晶度。 (8)红外化学成像技术可以用来分析不同链/支比玉米品种不同位置处淀粉吸水能力、老化能力、蛋白质含量等的差异：

The crystallinity of ae du starch is the lowest of the five kinds of starch, indicating that the introduction of du gene reduces the crystallinity of starch granules. (8) Infrared chemical imaging technology can be used to analyze the differences of starch water absorption capacity, aging capacity, protein content, etc. at different positions of corn varieties with different chain/branch ratios:

1)wx ae玉米淀粉吸水能力更强。WT玉米淀粉颗粒结晶状态均一,较难吸收水分。ae玉米颗粒中部和基部淀粉较WT玉米吸收水分多。GEMS-0067和ae du玉米颗粒冠部和基部的淀粉吸水能力与ae也有不同。

1) Wx ae corn starch has the strongest water absorption ability. WT corn starch granules have uniform crystalline state and are difficult to absorb water. The starch in the middle and base of ae corn grain absorbs more water than that of WT corn. GEMS-0067 and ae du also have different water absorption capacity of starch at the crown and base of corn granules from ae.

2)WT、ae和GEMS-0067玉米淀粉老化能力相当。wx ae品种玉米淀粉不易老化。ae du玉米颗粒冠部淀粉较其它两位置处淀粉易老化。3)WT玉米蛋白质整体来说含量,淀粉含量更多,淀粉颗粒在WT玉米颗粒中得到了充分的积累。ae玉米品种各位置淀粉含量较WT减少,蛋白质增多。wx ae品种与其它品种比较,变化更突出,蛋白质含量,且冠部和中部高于基部。ae du玉米与ae相比,淀粉多,蛋白质少。GEMS-0067玉米冠部和中部位置淀粉和蛋白质相对含量与ae品种类似。

2) WT, ae and GEMS-0067 corn starch have the same aging capacity. Wx ae maize starch is not easy to age. The starch in the crown of ae du corn granules is easier to age than that in the other two positions. 3) WT corn has the lowest protein content and the highest starch content, and starch granules have been fully accumulated in WT corn granules. Compared with WT, the starch content in each position of ae maize varieties decreased and the protein content increased. Compared with other varieties, wx ae varieties had the most prominent changes, the highest protein content, and the crown and middle were higher than the base. Ae du maize has more starch and less protein than ae. The relative content of starch and protein in the crown and middle of GEMS-0067 maize is similar to that of ae maize.
