中文摘要:

为研究不同生长环境对燕麦淀粉品质的影响，分别选取同时在我国两大燕麦主产区内蒙古和河北省种植的10个裸燕麦品种，测定其抗性淀粉含量、总淀粉含量、糊化特性和淀粉水解率，通过多重比较分析品种的变异性和地区之间的差异性。结果表明，两地区内参试样品间的抗性淀粉、总淀粉、峰值黏度、破损值和回生值的差异均较大；两地区之间，抗性淀粉和总淀粉含量存在显著差异（P<0.05），淀粉水解率以及大部分糊化特性存在极显著差异（P<0.01）；内蒙古地区种植的燕麦样品淀粉水解率、糊化温度极显著（P<0.01）高于河北地区种植的燕麦样品，而峰值黏度、破损值、回生值极显著（P<0.01）低于河北地区的样品。

英文摘要:

In order to analyze the effects of cultivation conditions on starch quality of naked oat , ten naked oat cultivars which were planted in Inner Mongolia and Hebei, the two main oat planting regions in China, were used as the materials. Resistant starch (RS), total starch (TS), starch pasting properties and starch digestion simulation in vitro of oat were determined. With multiple comparison methods, differences among the ten samples and between the two areas were analyzed. The results indicated that there are significant differences for the resistant starch, total starch, peak viscosity, breakdown and setback among the oat samples of each region. There are significant differences for the resistant starch and total starch between two regions, there are more significant differences in starch digestion simulation in vitro and most starch pasting properties between two regions. The starch digestion simulation in vitro and pasting temperature of Inner Mongolia samples are significant higher than those of Hebei. The peak viscosity, breakdown and setback of Inner Mongolia samples are significant lower than those of Hebei.
