小麦外观与其品质之间的相关性分析

小麦质量的快速判断在饲料生产中具有重要意义。为尝试通过外观快速鉴定小麦品质,试验测定了各类小麦的理化组成和霉菌毒素含量,探寻小麦外观与其品质之间的相关性。采用国标法测定小麦理化组成、采用酶联免疫法测定小麦中各类霉菌毒素含量。结果显示,不同外观的小麦其百粒重、灰分、粗蛋白质和淀粉量存在一定差异,且其呕吐毒素的含量差异显著,其中赤霉病粒、瘪粒、不饱满粒、破碎粒小麦的呕吐毒素含量很高,直接影响小麦品质。因此,可通过外观(如饱满度、赤霉病粒、破碎粒数量)等鉴定小麦品质。

Analysis of Correlation between Wheat Appearance and Quality

To identify the wheat quality quickly in the production of feed, the experiment classified the wheats, tested various wheat physicochemieal composition by using national standards and mycotoxin content with En- zyme-linked immuno sorbent assay （Elisa）, and tried to explore the correlation between the appearance and quality of wheat. The results showed that, the 100-seed weight, ash, crude protein and starch content were different among the wheats in different appearance, and the vomitoxin was significantly higher in the wheats of gibberellic, shrunk- en, not full and broken. The apprarence was directly affect wheat quality. Therefore, the ration of appearance of full- ness, gibberellic, broken wheat could used to identify quality of wheate.
