[By Cho Seong-je, Korea Farmers' Newspaper] The Gyeongbuk Agricultural Technology Institute urged careful management of vineyards during high-temperature periods to ensure stable grape production, as early heat waves have increased physiological disorders such as grape axial disease and sunburn symptoms. Axial disease occurs when temperatures exceed 33°C, causing increased transpiration that deprives fruits of moisture and creates uneven, sunken surfaces that reduce marketability. Sunburn symptoms refer to plant tissues like leaves and fruits dying due to high temperatures and intense sunlight, also known as heat damage. When affected by these symptoms, grape clusters lose their commercial value due to poor shape, and in cases where entire clusters are damaged,

The Gyeongbuk Agricultural Technology Institute urged careful management of vineyards during high-temperature periods to ensure stable grape production, as early heat waves have increased physiological disorders such as grape axis disease and sunburn. Axis disease occurs when temperatures exceed 33℃, causing increased transpiration that deprives fruits of moisture, resulting in uneven depressions that reduce marketability. Sunburn is a phenomenon where plant tissues like leaves and fruits become damaged or die due to high temperatures and intense sunlight. These symptoms can cause poor grape cluster shapes, losing commercial value. When entire clusters are affected, harvest yields can significantly decrease, making it crucial for farmers to manage vineyards during high-temperature periods to protect quality and quantity. First, appropriate fruit load must be maintained. Based on 10a (300 pyeong), it is appropriate to produce less than 2 tons at final harvest. Excessive fruit load ...
