Which of the following is an example of a specialty crop that requires specific chilling hours?

Peaches are an example of a specialty crop that requires specific chilling hours to break dormancy and produce fruit effectively. Chilling hours refer to the time that temperatures are between 32°F and 45°F (0°C to 7°C) during the winter months. For certain fruit trees, such as peaches and apples, accumulating enough chilling hours is crucial because it ensures proper flowering and fruit set in the growing season.

In the case of peaches, they need a certain number of chilling hours to overcome their winter dormancy. If they do not receive enough chilling hours, the trees may underperform in terms of bloom time and fruit yield, leading to reduced production. Apples also require chilling hours, which supports the answer provided. However, peaches are often highlighted specifically due to their stringent chilling hour requirements and sensitivity to sufficient cold periods.

While oranges and grapes do have ideal climates and conditions for growth, they typically do not require the same chilling hours as the stone fruits do. Oranges thrive in warmer climates and are less dependent on cold temperatures for successful fruiting, focusing more on heat units for growth. Grapes, particularly certain varieties, can have different chilling requirements but primarily thrive with a hot climate and can adapt to varying conditions. Thus, while apples
