Avaliação de procedências de Parkia multijuga Benth na fase inicial de desenvolvimento no município de Sinop-MT

Abstract

The present study aimed to evaluate different provenances of the species Parkia multijuga Benth to identify patterns of genetic variability. Despite being endemic to the Amazon region and holding notable relevance both economically and ecologically, there is virtually no information in the literature regarding the genetic variability of the species. Biometric characteristics of the seed (length and width), germination percentage, and growth characteristics (diameter and height) were evaluated 30 days after sowing for three provenances in the vicinity of the municipality of Sinop: EMPAER (Mato Grosso Research, Assistance, and Rural Extension Company), Municipal Natural Park Botanical Garden (PNMJB), and Municipal Forest Natural Park (PNMF). The experimental design was a randomized complete block with 3 replicates, with plots consisting of 14 plants, totaling 126 plants. The results revealed differences among the provenances for the characteristics: seed width, germination percentage, and stem diameter, highlighting the possibility of success with the implementation of genetic improvement and conservation programs.
