Avaliação da variabilidade no desenvolvimento de mudas de Byrsonima cydoniifolia A. Juss.

Abstract

Murici (Byrsonima cydoniifolia A. Juss.) is a fruit species native to the Cerrado that, due to the characteristics of its fruits, presents enormous potential for acceptance by the consumer market. The degradation of the cerrado, combined with the growing interest in the murici fruit, previously harvested only through extractive methods, led farmers to turn to seedling production and the cultivation of murici on a commercial scale. However, there is a lack of studies that develop a seedling production system that can offer, in a shorter time, plants with high genetic and phytosanitary standards. In this context, the present study aims to evaluate the variability in the development of different genotypes of murici (Byrsonima cydoniifolia A. Juss), for seedling formation under commercial nursery conditions. For this purpose, an experiment was set up in a completely randomized design with different replicates that consisted of evaluating the development of plant height (cm), basal stem diameter (mm) and the number of leaves/plant of five different genotypes. According to the results obtained, it was found that the genotypes showed good development, both in height and basal diameter of the stem and number of leaves for the substrate and container used. The different genotypes evaluated did not show differences in the development of seedlings in terms of height and number of leaves, but there was significant difference in the basal diameter of the stem. The height of the seedlings at the time of pricking out does not constitute a significant difference for the seedlings to develop in height. It is suggested that the production of Byrsonima cydoniifolia A. Juss seedlings begins in July so that there are plants with adequate height for commercial planting by the beginning of November.
