Hermiston 2002 stripe rust disease gradient

This file contains the disease gradient data from Hermiston 2002 experiment for stripe rust on wheat. The experiments were reported in [Sackett, K. E., and C. C. Mundt. 2005. Primary disease gradients of wheat stripe rust in large field plots. Phytopathology 95:983–91.] 1st column: distance from the source of infection in feet. 2nd column: distance from the source of infection in meters. 3rd, 4th, 5th columns disease severity (percentage of leaf area infected) measurements in three replicate plots. This disease gradient is plotted in Figure 2(a).

本文件包含2002年赫米斯顿（Hermiston）试验中针对小麦条锈病的病害梯度数据。相关试验成果已发表于[Sackett, K. E. 与 C. C. Mundt. 2005. 大型田间小区中小麦条锈病的原生病害梯度. 《植物病理学》(Phytopathology) 95:983–91.]。
数据集各列信息如下：第1列为距侵染源的距离（单位：英尺）；第2列为距侵染源的距离（单位：米）；第3、4、5列为3个重复试验小区的病害严重度（即叶片受侵染面积占总叶面积的百分比）测定值。该病害梯度数据已绘制于图2(a)中。
