Yölämpötiloja

Yölämpötiloja refer to the minimum daily temperature thresholds required for certain cold-hardy plant species to grow and thrive in a given area. These thresholds are typically expressed in hours below a certain temperature per day, and are used to determine the suitability of a location for crops that require a certain level of cold treatment to germinate or grow.

In Europe, for example, the minimum temperature thresholds for strawberries are typically set at 75 hours below 7.2°C (45°F), while for potatoes the threshold is 126 hours below 6.7°C (44°F). These thresholds are essential for determining the feasibility of growing specific crops in a region, as they take into account the local climate and the duration of exposure to cold temperatures that plants require.

Nighttime temperatures have a significant impact on plant growth, as they affect the rate of respiration, endorphin production, and other physiological processes. Crops that are subject to prolonged periods of cold stress may suffer from reduced yields, stunted growth, or other impairments.

Farmers and agronomists use the nighttime temperature thresholds for various crops to make informed decisions about seed choice, sowing dates, and farming practices. However, these thresholds can vary depending on the specific variety of the crop, soil quality, and other environmental factors. As a result, it is essential to consult detailed tables and guides that provide specific thresholds for various crops in different regions.

In an increasingly warmer climate, it is essential to consider alternative daytime temperatures that provide optimal conditions for young plant growth and higher yields, not just hours under which plant can tolerate low temperatures.
