Abstract

Indole butyric acid (IBA) is a widely disseminated form of auxin in the asexual propagation of plants by optimizing rooting response and, in a scenario of climate change where thermal and water stress are imminent, the use of technology proves to be an opportunity to stimulate the expression of morphological characteristics of the roots, which can aid through stress. Therefore, this study aims to identify the discrepant characteristics between two genotypes, contrasting the drought of C. canephora, and to evaluate the effects of the application of IBA on these characteristics for seedling production by cutting. Thus, an experiment was set in a randomized block design, factorial scheme 2 x 2; the first factor consisted of genotypes (LB1 and 02) and the second, application of IBA. After 120 days, the seedlings were evaluated for morphological and anatomical characteristics, and the data was submitted to analysis of variance, Tukey's test at 5% probability, correlation and principal component analysis, using the R Studio software. There was no interaction between IBA and genotype for seedling shoots. However, for the other characteristics, there was influence of genotype, where 02 presented an increase in dry matter, changes in the dimensions of anatomical structures and changes in root architecture, through the increase in surface area and length of fine roots while LB1 showed gains only in root attributes. Consequently, the use of IBA proves to be a strategic resource in the expression of characteristics in the rooting of genotype 02, bringing improvements in seedling quality.

    Full Professor at UFES since 2016. He has a degree in Agronomy from UFES (1989), advanced training in Plant Tissue Culture (1991), a master's degree in Phytotechnics (1993) and a PhD in Genetics and Breeding from UFV (2000). Between 2013 and 2014, they carried out post-doctoral activities, passing through UFV and the University of Almería, in Spain. His awakening to teaching and research took place during his undergraduate studies where he was a monitor, for three semesters, of the subjects in the area of Statistics of the Agronomy course (Basic Statistics, Statistical Methods, Experimental Techniques), and during the same period, he was a scholarship holder for CNPq Scientific Initiation, with experiments carried out in the field, an occasion in which we can demonstrate our experiments, in a practical way, the content of the monitoring disciplines. He joined as a professor in 1993, at UFES, at the Center for Agricultural Sciences (CCA / UFES) after a public competition in the area of Biotechnology. At CCA he taught until June 2006, during which time he taught various subjects to undergraduate students studying Agronomy, Forestry Engineering, Animal Science and Veterinary Medicine.
