Effect of Photo-Selective Nets on Yield, Fruit Quality and Psa Disease Progression in a ‘Hayward’ Kiwifruit Orchard

نویسندگان

چکیده

The influence of the colour photo-selective nets on Actinidia deliciosa yield, fruit quality and progression bacterial kiwifruit canker (Pseudomonas syringae pv. actinidiae, Psa) need to be characterised due increasing use these nets, mainly protect from hail storms. From May 2019 onwards, pearl (Pn), yellow (Yn) grey (Gn) were installed permanently in a ‘Hayward’ orchard NW Portugal uncovered plants used as control. Compared outside conditions for both seasons, blue:red ratio mean air temperature higher (mean increase 12.7% 0.6 °C, respectively) photosynthetic active radiation (PAR) was lower (10.8% less between budbreak bloom) under Pn. Crop compared control, decreased by 40.3% three 2020, 23.9% Yn Gn 2021. Yield grade Pn similar that crops 2021, overall Gn. Photo-selective did not affect parameters. Psa control during two months although this beneficial impact needs further evaluation.
