[目的]为了迅速准确的对中国各农业遗址中的淀粉粒残留物进行鉴定,需要进行现代植物淀粉粒形态变化研究和模拟实验分析不同试剂和实验处理方法对淀粉粒形态的影响。[方法]研究现代小麦成熟过程中淀粉粒形态变化,完成了对成熟小麦的一系列模拟试验,如：研磨、超声波处理、盐酸和双氧水处理、干燥处理。[结果]成熟过程中小麦淀粉粒经历了由小到大的变化,最后稳定在由大、小两组淀粉粒组成;研钵研磨会使小麦淀粉粒粒径增大;较长时间的超声波处理使得小麦淀粉粒粒径增大;浓度为10%的盐酸和浓度为6%双氧水对小麦淀粉粒的影响很小;低温干燥处理不会使小麦淀粉粒出现糊化。[结论]该研究结论可有效地指导考古遗址古代样品淀粉粒分析实验流程以及处理参数的选择,提高了淀粉粒分析的效率和结果的可靠性。同时也为中国的农业起源和作物传播的研究提供了基础实验资料。

[Objective] The aim was to research and identify starch grain microfossil found in archaeological sites in China, and to find appropriate procedures for the starch grain analysis experiment.[Method] Wheat starch grain size distribution was analyzed, and some simulated experiments were carried out, like mortar grinding, ultrasonic treatment, hydrochloric acid and hydrogen peroxide immersion, drying treatment, and so on. [Result] The mean size of wheat starch grains had increased in the growth process. Mortar grinding would make wheat starch grains larger than untreated sample. Long time of ultrasonic treatment can also make the starch grain size larger. 10% HCl and 6% H2O2 would have little effects on morphological feature of wheat starch grains. Low temperature heating did not cause starch grains to be gelatinized. [Conclusion] These experiment results can improve the accuracy of starch grain microfossil identification in the archaeological site. Starch grain analysis may be a utility and effective analytical tool in studying the origin of agriculture and the dispersal of crops in China.
