Under two levels of earing fertilization (N0 and N2), compared with 25℃ treatment, heat stress (35℃) accelerated the grain filling and resulted in less grain weight, and also reduced the two glutelin subunits content of both fertilization treatments 12.1% and 5.7% respectively, and reduced the prolamin content of them 6.7% and 4.9% respectively. Simultaneously, the polypeptides above 57 kD was increased 18.8% and 11.7% respectively, and grain crude protein content was also increased 0.56% and 0.35% respectively.

在N0和N2两个穗肥水平下,35℃高温处理均提高了子粒灌浆速度,明显降低了子粒单粒重;35℃高温处理还使谷蛋白的两个亚基的含量较25℃处理分别降低12.1%和5.7%,使醇溶蛋白含量分别降低6.7%和4.9%,同时却使谷蛋白组分中57kD及以上多肽的积累分别增加18.8%和11.7%,且子粒的粗蛋白含量也分别增加0.56%和0.35%。

晚更新世末期三角洲粒径较粗,有孔虫和介形类的氧化壳含量较高,有孔虫和介形类的丰度和含量也较高,CaCO3的含量较高,与现代三角洲形成明显的对照。

The results suggested that compared with A-starch and maize starch, there are more quantities of impurities, such as protein, lipid and pentosan, in B-starch. B-starch prepared in the laboratory almost has the same compositions as three samplings, and accords with the reports of some documents too. Differing from the granules in A-starch, those in B-starch are smaller sized (1-10m)and oval shaped, and felted each other. The crystallogram of A- and B-starch are similar, i.e. A type. There is difference in granular distribution between A- and B-starch. The granular distribution of B-starch is anomalous and extensive (l~1259m).B-starch has bigger dilatancy and retrogradation, and smaller blue value, solubility, viscosity, gelatinization temperature and gelatinization enthalpy.

试验结果表明:跟玉米淀粉、A淀粉相比较,B淀粉含有的蛋白质、脂肪和戊聚糖等杂质数量多;实验室制备的小麦B淀粉中淀粉、粗蛋白、戊聚糖等含量均与文献的报道接近,也与在工厂采样的B淀粉相近;与A淀粉不同,B淀粉以小颗粒的淀粉为主,平均粒径1~10μm,颗粒形状呈椭圆形,同时颗粒和颗粒之间黏结紧密;B淀粉和A淀粉晶形结构相似,都为A型;B淀粉的粒度分布情况不同于A淀粉,其粒度分布规律性不强,分布范围也较宽,粒度在1~1259μm之间;B淀粉的凝沉值和膨润力大于A淀粉,而沉降体积、蓝值、溶解度、粘度、糊透光度、相变温度和热焓均小于A淀粉;杂质的含量对B淀粉性质的影响是明显的,随着杂质含量的增加,沉降体积、溶解度和透光度减小,膨润力增大,但是它们对凝沉值、蓝值和粘度的影响比较复杂。
