Under the long-term shading conditions, the development of starch granule was suppressed during the mid to late grain filling stage, as a result of decline in peak diameter, reduced range of max diameter and enlargement of small granules. 遮光处理条件下,在灌浆中期和后期小麦籽粒淀粉粒合成受到了抑制,造成了籽粒淀粉峰值粒径后移程度下降、最大粒径范围缩小以及灌浆后期小淀粉粒增殖与增大受抑制等。
