| English abstract | A net shield is a good option for protection of apple trees against hailstorm, especially for small orchards. The shading effects caused by net shield on production feature and fruit quality was evaluated for five years. Three types of net shield that caused 12%, 18% and 30% of shading were used on 'Gala' and 'Fuji' apple trees. Reduction of fruit red color was the main negative effect of shading. Fruit red color was reduced up to 14.2 % for 'Gala' and 7.2 % for 'Fuji' when net shield was applied. The shading also reduced incidence of fruit with 'russeting' but increased incidence of 'glomerela' spot. Apple trees covered with the net for five years developed approximately 19% less bud flowers than uncovered trees |
| Portuguese abstract | A cobertura do pomar com telas de náilon é uma opção de combate ao granizo, principalmente em pequenas áreas. Durante cinco anos, avaliou-se o efeito do sombreamento provocado pela tela antigranizo, com níveis de sombreamento de 12%, 18% e 30%, sobre os fatores de produção na macieira, cvs. Gala e Fuji. A coloração vermelha dos frutos foi a variável mais afetada pelo sombreamento, reduzindo-se até 14,2% da coloração na cv. Gala e 7,2% na cv. Fuji. O sombreamento reduziu a incidência de "russeting" nos frutos, mas aumentou a incidência da mancha de glomerela. No último ano de avaliação, as plantas com cobertura de tela apresentaram uma redução de 19% no número de gemas com flor, quando comparadas com as plantas sem cobertura |
