Produção de frutos e caracterização morfométrica de Murici (Byrsonima cydoniifolia A. Juss) do banco de germoplasma 2015 - Barra do Garças - MT

Abstract

Byrsonima cydoniifolia A. Juss popularly known as Murici is a fruit plant belonging to the Malpighiaceae family whose fruits are of great popular appreciation, both in fresh consumption and in several other ways, in addition to their medicinal use. It is a species native to Brazil, with the legal amazon being its center of dispersion. There is little productive and morphometric information about this species. The morphometric and productive characterization provides important data for the correct exploitation and conservation of the species, helping to detect genetic variability within different existing populations. The objective of this work was the morphometric characterization and fruit production of B. cydoniifolia existing in the Germplasm bank of the Federal University of Mato Grosso – Campus Universitário do Araguaia, city of Barra do Garças - MT. Progenies from eight populations from the middle Araguaia region were analyzed, measuring the following morphometric characteristics: plant height; stem diameter; cup diameter; internode length; sheet length; sheet width; leaf petiole length; leaf petiole width and fruit production. Means and standard deviations were estimated for all characteristics and the t test was performed for the morphometric characteristics. It was verified the existence of great variability in the morphometric characteristics, allowing the selection of genotypes for commercial cultivation purposes. The populations most recommended for larger spacings were Amado Batista, Ouro Fino and Patizal, the most recommended for smaller spacings was the Santo Antônio population, however, it was felt the need to carry out other statistical analyzes to know the relationships between morphometric and production characteristics of fruits.
