Abstract
INTRODUCAO Os processos fisiologicos responsaveis pelo crescimento e produtividade das plantas cultivadas sao diretamente influenciados pelos fatores climaticos (SILVA JUNIOR et al., 2012). A radiacao solar e a fonte primaria [...]
In order to study variations in growth, partitioning of assimilates and fruit production of melons, Yellow types 'Gold Mine' under crops shaded by different meshes were evaluated. The experiment was carried out in field Research, Department of Plant Science, Universidade Federal de Vicosa, in the period from 24/11/2008 to 11/03/2009.The treatments were four culture environments: control (full sun) and under the Aluminet® 30%-O, Cromatinet® 30% and Sombrite®, 30% meshes with reductions in solar radiation, 30.85, 35.9 and 32.0%, respectively. The experimental design was completely randomized, with four replications. For the characteristics evaluated periodically it was used the split-plot design with environments allocated to plots and subplots periodic reviews. Among the shaded environments, melon cultivation in the mesh Aluminet® 30%-O was the treatment that stood out in terms of plant growth and fruit yield. Key words: Cucumis melo, shading, leaf area, dry mass, productivity. Objetivou-se avaliar variacoes no crescimento, na particao de assimilados e na producao de frutos de melao, tipo Amarelo 'Gold Mine', sob cultivos sombreados por diferentes malhas. O experimento foi conduzido na Horta de Pesquisas do Departamento de Fitotecnia da Universidade Federal de Vicosa, no periodo de 24/U/2008 a 11/03/2009. Os tratamentos foram constituidos de quatro ambientes de cultivo: controle (pleno sol) e sob as malhas Aluminet® 30%-O, Cromatinet® 30%-O e Sombrite® 30%, com reducoes, na radiacao solar incidente, de 30,8, 35, e 32,0%, respectivamente. O delineamento experimental foi o inteiramente casualizado, com quatro repeticoes. Para as caracteristicas avaliadas periodicamente, utilizou-se o esquema de parcela subdividida com os ambientes alocados nas parcelas e as avaliacoes periodicas nas subparcelas. Dentre os ambientes sombreados, o cultivo do meloeiro sob a malha Aluminet® 30%-O foi o tratamento que mais se destacou em termos de crescimento de planta e producao de frutos. Palavras-chave: Cucumis melo, sombreamento, area foliar, massa seca, produtividade.
