Spring frost can have severe effects, including bud and shoot mortality, delayed growth, reduced yield, and impacts on both the current and following years.
During spring, temperatures below 0 ˚C, and especially those below -2.5 ˚C, can damage the vine at the onset of vegetative growth.
Temperatures in this range can cause significant damage to grapevines, including damaged winter buds and even mortality.
Shading the berries with leaves can reduce solar radiation exposure and lower the temperature of the berries.
Sunlight is essential for photosynthesis, light-activated processes, and influencing vine growth and fruit ripening through its thermal effects, making it crucial for plant life and agricultural practices.
Climate is the average weather conditions in a region over a long period, typically over 30 years, encompassing the overall trends and patterns.
Weather refers to the state of the atmosphere at a particular place and time, including temperature, humidity, precipitation, wind, and visibility, and it changes from day to day or even hour to hour.
Anticyclones are high-pressure systems where air sinks and rotates clockwise in the Northern Hemisphere, leading to generally fair and stable weather.
Sunlight can inhibit the development of certain diseases in plants by creating less favorable conditions for pathogens.
Sunlight transforms light energy into chemical energy, enabling the synthesis of carbohydrates and other organic compounds, and influences vine growth and fruit ripening.
Grapes can be adversely affected by extreme heat when temperatures exceed 35 ˚C.
