Abstract

Two standard area diagrams (SADs) were developed to quantify the severity of tomato early blight (EB), caused by Alternaria solani, on leaves and leaflets. The SADs were composed by sets of images with distinct EB severity for leaflets (0–40%) and leaves (0-46.4%). To validate the diagrams, 13 evaluators with no experience in quantifying the plant disease severity estimated EB severity by using a 50-image sample of tomato leaves and leaflets, first without SADs and then using the proposed SADs. The data were submitted to regression analysis and Lin’s concordance correlation coefficient, and the accuracy, precision, repeatability, and reproducibility of the estimates for EB severity were assessed. Based on the parameters of Lin’s coefficients and intraclass correlations, EB severity estimates were consistent and more reliable using SADs, improving evaluators’ performance. The diagrams proposed in this study improved the quantification of EB severity performed by 13 evaluators, increasing the accuracy, precision, and reliability of the estimates. Therefore, the proposed diagrams can be used in further studies on the epidemiology, resistance, and management strategies of this pathosystem.

用于评估番茄叶片和小叶早疫病严重程度的标准面积图

摘要开发了两种标准面积图（SAD），用于量化叶片和小叶上由Alternaria solani引起的番茄早疫病（EB）的严重程度。标准面积图由小叶（0-40%）和叶片（0-46.4%）上不同 EB 严重程度的图像集组成。为了验证这些图表，13 位没有植物病害严重程度量化经验的评估员使用了 50 张番茄叶片和小叶的图像样本来估算 EB 严重程度，首先不使用 SAD，然后使用建议的 SAD。对数据进行了回归分析和林氏一致性相关系数，并评估了 EB 严重程度估计值的准确性、精确性、可重复性和再现性。根据林氏系数和类内相关系数的参数，使用 SAD 估算 EB 严重程度更一致、更可靠，从而提高了评估者的绩效。本研究中提出的图表改进了 13 位评估者对 EB 严重程度的量化，提高了估计值的准确性、精确性和可靠性。因此，所提出的图表可用于进一步研究该病理系统的流行病学、抗药性和管理策略。
