Plant Pollinator interactions in high temperatures

environmental temperature: Impact of radiant heat and humidity A glasshouse air temperature of 30° C at a humidity of 80% can still results in good pollination [...] conventional greenhouses, the recommended humidity range is 60-75%. Due to better air movement, the range in a semi-closed greenhouse is 70-85%. Setting malfunction [...] of poor setting can be found near the climate chamber because of hot, dry air movements caused by momentum. This exhaustion related type of poor setting
