Abstract

The study of the growth and development of a plant under different environmental conditions offers the researcher a good clue as to which are the best conditions to grow a particular species. The main objective was to evaluate the initial growth, for up to 80 days, for of Schizolobium parahyba check for this species in other resources (guapuruvu) seedlings submitted to the shading levels: 0% (full sunshine), 30%, 50% and 70% shading. The results demonstrate that the shading interfered positively in the growth in height of the seedlings, even at the greatest levels, and did not cause damage to the plants, which was proven by the lack of differences in the variables: dry matter, lap diameter and number of pairs of leaves. The production of quality seedlings is favorable up to the 45th day of submission to shading, after which seedlings should be transplanted.

Keywords

Resumo

O estudo do crescimento e desenvolvimento de plantas em diferentes ambientes oferece respostas sobre as melhores condições para as espécies serem cultivadas. Objetivou-se avaliar o crescimento inicial até 80 dias em mudas de Schizolobium parahyba check for this species in other resources (guapuruvu) submetidas aos níveis de sombreamento: 0% (pleno sol), 30, 50 e 70%. Os resultados demonstram que o sombreamento interferiu positivamente no crescimento em altura das mudas, apresentando tendência nos maiores níveis, não causando danos às plantas, fato comprovado pela não diferença das variáveis: matéria seca, diâmetro de colo e número de pares de folhas. É favorável a produção de mudas com qualidade até o 45o dia de submissão ao sombreamento, devendo ser transplantadas após esse período.

Palavras-chave
guapuruvu; luminosidade.
