Yield and diametric structure of Dimorphandra mollis Benth.

Authors

Abstract

Dimorphandra mollis is native to the Brazilian Savanna and has social, economic and environmental importance. This study aimed to evaluate the yield and diametric distribution of Dimorphandra mollis Benth. in the Pandeiros River Environmental Protection Area, in Bonito de Minas, Minas Gerais state, Brazil. Five areas were assessed, totaling five hectares (50 plots of 1,000 m2). The total number of plants, yield per plant (2018, 2019 and 2020) and diameter at breast height were recorded, considering all trees from the plots in diametric classes. The average diameter at breast height of all plants was 6.05 ± 3.07 cm, and that of the plants that produced in at least one of the evaluated years was 7.46 ± 3.15 cm. The diametric distribution showed classes with no individuals, indicating imbalance, as well as a trend to inverted “J” shape. The maximum annual yield was 8.08 kg ha-1 of dry fruits (2019), the minimum 0.42 kg ha-1 (2018), and the average 2.74 kg ha-1, with biennial characteristic.
