Crescimento da rebrota de Cordia trichotoma (Vell.) Arrab. ex Steud. manejado por talhadia em sistema ILPF

Abstract

The use of native forest species in production systems constitutes an important alternative for the diversification of Brazilian forestry and for the development of more sustainable production models. In this context, the present work aimed to analyze the resprout growth of Cordia trichotoma (Vell.) Arráb. ex Steud. under coppice management in an Integrated Crop-Livestock-Forestry (ICLF) system. The experiment was conducted in the experimental area of the Federal Technological University of Paraná (UTFPR), Dois Vizinhos Campus, using laurel-pardo individuals approximately 10 years old. Different fertilization levels were evaluated, and variables related to resprout growth were monitored monthly for 14 months, including height, sprout diameter, number of sprouts per stump, stump diameter, and sprout origin. The data were subjected to descriptive statistical analysis and analysis of variance. The results demonstrated a high capacity for vegetative regeneration of the species after stump cutting, with a predominance of lateral shoots and continuous shoot growth throughout the evaluation period. Statistical analyses did not indicate significant differences between fertilization treatments for the variables evaluated. It is concluded that Cordia trichotoma shows potential for management under coppice control in integrated crop-livestock-forestry systems (ICFS), contributing to expanding knowledge about the management of native forest species in integrated production systems.
