摘要
对甘肃省玉米种植主导品种金穗4号玉米籽粒的压缩和剪切力学性能进行了实验研究,采用针尖压入法对玉米籽粒各组分的硬度作了试验分析。实验结果表明,含水率以及压缩和剪切位置对玉米种子籽粒静压破损特性和硬度有明显的影响;角质胚乳的硬度明显高于粉质胚乳和胚,而粉质胚乳的硬度略高于胚。
It was studied that the compression and shear properties of corn which is leading breed called JinSui-4 in Gansu Province,the hardness of each component of the corn grains is experiment analyzed adopting needlepoint pressing-in method.The test results points out that the moisture content and the position where the corn is pressed effect on static pressing property and hardness of corn grains obviously;the hardness of the cutin endosperm is obviously higher than powder endosperm and embryo,and the hardness of the powder endosperm is higher than embryo,when moisture content ratio increases,the hardness of corn is decreased.
