What minimum temperature is required for apple production?
A
10°C
B
4.5–5.5°C
C
8–10°C
D
2–3°C
Correct Option:
B
Explanation
Among the given options, 4.5–5.5°C is the best answer. Apples generally need a cool temperate climate, and requirements vary by cultivar and growth stage. The additional figures sometimes quoted—such as 1,000–1,500 hours below about 7°C and 21–24°C during active growth—are cultivar- and region-dependent.
