Physiological and Structural Changes in Apple Tree Branches of Different Varieties during Dormancy

open access: yesHorticulturae, 2023
Low temperature is an abiotic stress factor limiting the distribution of fruit tree cultivation areas. As temperate deciduous fruit trees, apple (Malus domestica) trees go dormant in the winter to adapt to or avoid damage caused by low temperatures.
