A wealth of information on the patterns of human subsistence and plant domestication has been generated from studies on maize (Zea mays) starch granules. However, very little work has been conducted on how the size and morphology of those granules might change as a function of water stress during the growing season. In the arid Southwest, the role of irrigation in growing maize is an essential parameter in many foraging models. Our study seeks to determine if there are significant changes in the size and other morphological attributes of starch granules from maize planted at Range Creek Canyon under two different irrigation regimes ranging from little water (once every three weeks) to ample water (once a day). Our results provide data on the effects of irrigation on Z. mays starch granules and, therefore, have implications for identifying archaeological maize and possibly determining past water regimes at Range Creek Canyon.

淀粉颗粒大小和形态作为水体对玉米影响的代表

对玉米（Zea mays）淀粉颗粒的研究已经产生了大量关于人类生存和植物驯化模式的信息。然而，关于这些颗粒的大小和形态如何随着生长季节的水分胁迫而变化的研究很少。在干旱的西南地区，灌溉在玉米种植中的作用是许多觅食模型中的重要参数。我们的研究旨在确定在从少量水（每三周一次）到充足水（每天一次）的两种不同灌溉方式下，种植在 Range Creek Canyon 的玉米的淀粉颗粒的大小和其他形态属性是否有显着变化. 我们的结果提供了灌溉对玉米淀粉颗粒影响的数据，因此，
