Interpretive Summary:

Technical Abstract: A method for characterizing root and shoot growth of citrus was developed using ArcView 3.2 and the Image Analysis extension. Digital images of citrus plants were analyzed for spectral characteristics using the image categorization tool into distinct spectral categories. The values of pixels associated with tissues of interest were initially identified. Based on this assessment, the categories of interest were calculated to a particular value in the attribute table. A query was then run to select these pixels in the table; these were subsequently converted to a polygon feature. The tissue area of interest was then quantified using the Xtool extension.
