Crescimento inicial e metodologia para avaliação de área foliar em Eugenia dysenterica DC sob níveis de sombreamento

Abstract

Eugenia dysenterica DC, popularly known as cagaiteira, is a native forest species of Cerrado Brasileiro. The cagaiteira is one of the native species of the Cerrado that has potential of use in systems of agricultural production, mainly due to the potential use of its fruits, leaves and bark to obtain food products, drug development and ornamentation. The light level is among the main limiting factors in seedling production in nurseries. The choice of the appropriate light level can be the main management used to ensure the success of the seedlings production and the quality of these seedlings. The objective of this study was to evaluate the growth of cagaiteira (Eugenia dysenterica DC) seedlings under three different levels of light and to test two methods of quantification of the leaf area. The experimental design was completely randomized in factorial scheme 3 shading (full sun, 30 and 70%) x 5 times (0, 30, 60, 90, 120 days) in three replications totaling 45 seedlings. It was observed that the shading of 70% is where the species best developed during the evaluated period. The major characteristics and qualities of Eugenia dysenterica DC seedlings were under 70% shading, indicating that the species is not demanding in light.
