Morphology of Dasylirion cedrosanum and its correlation with images in localities of Southeastern Coahuila

Digital image processing is a tool that facilitates morphological analysis. Therefore, it was proposed to evaluate the morphological characteristics of sotol plants using digital images. For this purpose, the following variables were taken: plant height, cover diameter, height and stem diameter of 10 plants in four localities of Coahuila. In addition, photographs were taken of each specimen and the morphological data were analyzed in the ImageJ program. Using linear regression and correlation analysis, a comparison was made between manually and digitally measured data. The results show that the manually determined variables are positively and significantly correlated with the variables of the digitally analyzed photographs. The use of photographs and digital analysis is a support tool to characterize the morphology and select the sotol plants.
