We present an all-inclusive software tool for dealing with the essential core of mathematical and statistical calculations in plant growth analysis. The tool calculates up to six of the most fundamental growth parameters according to a purely classical approach across one harvest-interval. All of the estimates carry standard errors and 95 % confidence limits. The tool is written in Microsoft® Excel 2000 and is available free of charge for use in teaching and research from www.aob.oupjournals.org article supplementary data (http://aob.oupjournals.org/cgi/content/full/90/4/485/DC1).
Key words: Relative growth rate, unit leaf rate, net assimilation rate, specific leaf area, leaf weight fraction, leaf area ratio, allometry.
