Vineyard protection with rain-shelter: relationships between radiometric properties of plastic covers and table grape quality
The rise of unpredictable, heavy rainfalls increases incidence of diseases, berry rot, berry cracking, and enhance the need for rain shelters. The influence of the type of rain shelter on microclimate and grape quality is still little explored. The aim of this trial was to investigate the radiometri...
