The potential of thermal imaging to assist winemakers in the detection of downy...
Portela, Fernando; Paredes, Cláudio A.; Sousa, Joaquim J.; Pádua, LuísVineyards represent one of the main crop systems of greatest importance in the world economy, both in terms of the value chain of wine production and in its current expression of generating tradable goods. One of the challenges of grape production is grapevine health, which annually forces the winegrowers to incur fixed costs associated with the prevention and/or treatment of pests and diseases, causing an impa...
Using aerial thermal imagery to evaluate water status in <i>Vitis vinifera cv.<...
Araújo-Paredes, Cláudio; Portela, Fernando; Mendes, Susana; Valín, Maria IsabelThe crop water stress index (CWSI) is a widely used analytical tool based on portable thermography. This method can be useful in replacing the traditional stem water potential method obtained with a Scholander chamber (PMS Model 600) because the latter is not feasible for large-scale studies due to the time involved and the fact that it is invasive and can cause damage to the plant. The present work had three o...
