Anti-hail nets may change the microclimate of orchards and hence modify the physicochemical and sensory characteristics of fruits. The present study aimed to evaluate the effects of anti-hail nets on the physical, chemical, and sensory attributes of apples grown in southern Brazil. The study was conducted in commercial orchards, with apples grown under a black anti-hail net under an open sky during the 2008/2009, 2009/2010, and 2010/2011 cycles. Measurements of photosynthetically active radiation were collected at both sites. Physical, chemical, and sensory analyses of fruits were performed in the laboratory. The anti-hail net reduced incident photosynthetically active radiation by 32 %. The light spectrum in the canopy changed the corresponding R/FR (red/far-red) ratio in the lower and upper canopy layers from 0.27 to 1.55, respectively. In contrast to the majority of microclimate studies carried out in the temperate zones of the northern hemisphere, this study in the southern hemisphere showed that although it reduced the incident solar radiation, the cover did not change the color or organoleptic characteristics of ?Royal Gala? and ?Fuji Suprema? apples. The net cover prolonged the subperiod between fruit setting and harvesting, thus slowing fruit ripening. Therefore, the use of anti-hail nets on apple orchards is a suitable alternative for the protection of apple trees against hail because it causes only small changes in the microclimate and in the maturation period, ensuring fruit production without affecting its quality.

O objetivo deste trabalho foi avaliar o desempenho de 12 combinações de três clones de painel (PB 311, PB 314 e RRIM 600) com quatro clones de copa (F 4512, MDF 180, IAN 6158 e IAN 6543) de seringueira cultivados no sudoeste do Estado do Mato Grosso. Utilizou-se o delineamento experimental de blocos ao acaso, com quatro repetições. Foram avaliados: produção de borracha seca, percentagem de plantas aptas à sangria, secamento de painel, estado nutricional, teor de borracha seca, plasticidade Wallace (P0 e P30), índice de retenção de plasticidade e viscosidade Mooney. As combinações das copas IAN 6543 e MDF 180 com os painéis PB 311, RRIM 600 e PB 314 apresentaram estado nutricional adequado, com produtividade de borracha seca acima de 1,41 Mg ha?1 por ano. O clone de copa IAN 6158 propiciou, em oito anos, as maiores quantidades de plantas aptas à sangria. As combinações painel/copa apresentaram baixa incidência de secamento de painel, exceto PB 311 x IAN 6158. As borrachas das 12 combinações painel/copa apresentam boa resistência à degradação térmica e alta retenção de plasticidade. |
