This lowers the moisture content in the tree, and can cause heat stress. There are thousands of different types of apples, but they broadly fall into two categories: dessert apples for eating, and cookers, as the name suggest, for cooking. Dependant on variety. In our study, the effects of water stress on photosynthesis and photosynthetic electron transport chain (PETC) were studied in several ways, including monitoring the change of gas exchange parameters, modulated chlorophyll fluorescence, rapid fluorescence induction kinetics, reactive oxygen species (ROS), antioxidant enzyme activities and D1 protein levels in apple leaves. Trees that are heat stressed during critical times, like bloom, will have reduced fruit set. Apples are probably the easiest tree fruit to grow and the most popular with gardeners. 7B, D and F). 10- and 15-year-old trees shifted their water sources from the 160–300 cm to 0–40 cm soil layers, and 22-year-old trees mainly exploited water from the 0–160 cm soil layers throughout the growing season (Fig. Foliar diseases, such as apple scab on crabapples, cause spotting of the foliage and premature leaf drop.
