dc.descriptionIndole butyric acid (IBA) is a type of auxin that is widely used in the asexual propagation of plants as it optimises the rooting response. In a scenario of climate change, where thermal and water stress are imminent, the use of technology has proven to be one way of stimulating the morphological characteristics of the roots, which can help mitigate the stress. The aim of this study was to identify differing characteristics between two genotypes, comparing the effect of water deficit on C. canephora, and to evaluate the effects of applying IBA on these characteristics when producing seedlings from cuttings. An experiment was set up using a randomised block design in a 2 x 2 factorial scheme where the first factor consisted of the genotypes (LB1 and 02) and the second, the applications of IBA. After 120 days, the morphological and anatomical characteristics of the seedlings were evaluated, and the data were submitted to analysis of variance, Tukey s test at 5% probability, and correlation and principal component analysis using the R Studio software. There was no interaction between IBA and genotype for the shoot system of the seedlings. However, there was an effect of genotype on the other characteristics, where genotype 02 showed an increase in dry matter, changes in the size of the anatomical structures, and changes in root architecture, with an increase in surface area and length of the fine roots, while LB1 showed an increase in the root attributes only. As a result, IBA proves to be a strategic resource for the expression of characteristics in the rooting of genotype 02, affording improvements in seedling quality.
