Abstract
QUINTANA, Silverio Andrés; MARIA GROSSI, Cecilia Eugenia; ESPINOZA, Rodrigo and ULLOA, Rita. Plantico, an R statistical analysis package for plant biometric parameters. Rev cuba cienc informat [online]. 2021, vol.15, n.4, pp. 45-60. Epub Dec 01, 2021. ISSN 2227-1899.
Abiotic and biotic stresses negatively impact on plant development affecting biometric parameters, such as root or shoot length, that can be measured at different time points. An adequate statistical analysis of the data is required to evaluate the effect of each stress condition. Thus, Plantico, an open-source R statistical analysis package that performs the analysis of variance (ANOVA) followed by Tukey´s test, as well as the bar, line, and box plots at a given "t” time of the assay was created. An assay was conducted with Arabidopsis seedlings grown in vitro under control (MS 0.5x), saline (MS 0.5X + 75 mM NaCl) or osmotic (MS 0.5 x + 100 mM mannitol) conditions and root length was determined to validate this package. Statistical analysis of the data and the corresponding graphs were performed with Plantico. This tool can be downloaded and used for free and can be modified to include other biometric parameters and time points. Plantico is a user-friendly package that enables statistical analysis and the visualization of experimental data.
