The vegetative growth period requires an effective accumulated temperature of about 3500°C to ensure the normal growth and results of the almond tree. In the deciduous fruit tree species, almonds are both resistant to heat and very hardy, and can tolerate short-term low temperatures of -27°C in the case of adequate dormancy. Some wild almonds are resistant to low temperatures of -40°C.

Low temperature during flowering is often the main reason affecting almond production. Under extreme cold conditions (eg, low temperature of -28°C) for 5-7 days, shoots from 1 to 3 years old can be frozen. Under -25°C conditions, flower buds can be frozen for 3-5 hours. , -15--10 °C can germinate flower buds to death. Amygdala is an early flower variety. After being released from dormancy, the ability to resist low temperatures is significantly reduced. Freeze damage occurs at a low temperature of -3-2°C in the flowering period. If the young fruit period is -l°C-O°C, it will cause frostbite. . The optimum temperature for pollination and fertilization of almonds is 15-18 °C. When the temperature dropped to 1.4-0.2°C, flower buds stopped developing.
