利用图像处理法快速测定小麦千粒质量

小麦是重要的粮食作物,千粒质量是小麦产量3要素之一.传统的千粒质量调查采用人工数粒、称质量的方法,既费时又容易出错.利用扫描仪成像和图像处理技术可以快速、准确地测量小麦千粒质量.以200dpi分辨率对小麦样品扫描成像,用Image-Pro Plus软件进行图像处理获得样品粒数,称质量后即可计算得到样品的千粒质量数值.通过录制‘宏’,还可以实现样品的批量快速处理.本方法简便易行、准确度高、误差小,可以大大缩短千粒质量调查所需时间.

On Rapid Determination of Thousand Grain Weight of Wheat by Means of Digital Imaging

Wheat is an important crop, and the thousand grain weight (TGW) is one of the indexes to be investigated in wheat breeding.The traditional manual counting method is time-consuming and error prone.This study has improved a quick and accurate assay to measure the TGW of wheat by means of digital imaging technology.Wheat samples have been scanned firstly with a scanner at 200 dpi resolution, then the Plus Image-Pro software has been employed to get the seed numbers of each sample quickly by image processing.Weighed the seeds and calculated the TGW.By recording''macro'', batch disposal of samples can also be realized.The method has presented in this paper is simple, accurate and can greatly save the time of TGW investigation.
