Fig. 3From: A new image-based tool for the high throughput phenotyping of pollen viability: evaluation of inter- and intra-cultivar diversity in grapevineCorrelation analyses (a, c) and Bland–Altman plots (b, d) comparing manual (MC) and automatic (AC) counting of total (a, b) and viable (c, d) pollen grains. In a and c, red solid lines shows linear regression line, whereas the identity line (x = y) is shown as a blue solid line. In b and d, red solid lines indicate the mean difference between both approaches, while upper and lower solid black lines represent limits of agreementBack to article page
