Morphometric characters as indicators of site quality of Tara spinosa (Leguminosae, Caesalpinioideae) in Cajamarca, Peru
Tara spinosa [= Caesalpinia spinosa Mol. (Kuntze)] (Fabaceae) is a highly valued species in the department of Cajamarca. However, despite being a plastic species that adapts to many altitudinal gradients and soil types, its site quality indicators have not been studied to date. In this sense, the objective of this research is to evaluate morphometric characters: plant height, length, width and pod weight, as indicators of site quality in 15 provenances of Cajamarca. The heights of the sampled trees were measured. Fifty nuts were collected on the plant and data were collected on length, width and pod weight. Soil samples were extracted from the A horizon to obtain 17 physicochemical factors, and climatic data were obtained from the sampling areas. Analysis of variance between morphometric characters was performed to determine the best provenances. Pearson's linear correlation analysis (p?0.05) between edaphic-climatic factors was performed to determine the linear association with the evaluated characters. It was determined that pod length and pod weight presented significant statistical differences (p?0.05), being these morphometric characters good indicators of site quality of Tara spinosa.
