摘　　要：以往植物病害常用的评估方法都是靠目视和经验评估,而利用计算机自动识别植物病害强度与定量的技术评估可以有效避免目测评估病害所造成的误差。本研究以小麦条锈病、苹果叶片褐斑病为例,介绍了图像处理软件ASSESS在植物病害评估中的应用。结果证明,ASSESS可以有效地对小麦条锈病、苹果叶片褐斑病严重度、病斑大小、病斑数目和根系长度等指标进行自动计算,其评估效果可靠,重复性较好。Plant disease assessment is a process to quantify plant disease intensity. Applying computer automatie identification can efficiently avoid error caused by visual assessment. This paper used some examples to introduce ASSESS software in evaluating plant disease. The results showed that ASSESS could make good assessment in disease severity, lesion measurement, number of lesion and root length measurement. Based on these terms, ASSESS can be used in field disease survey and analysis, plant resistance breeding and so on. Use of software can promote plant protection experts and workers making disease assessment more precise and accurate.
