Why do grapes crack?

Why do grapes crack? What is the reason? The main reasons for grape fruit cracking are as follows: 1. In the late stage of fruit growth, the soil moisture changes too much, the root absorbs a large amount of water from the soil and transports it to the fruit, and the physiological activity and division of the cells near the fruit brush accelerate. On the other hand, the cell activity near the pericarp is slow, which makes the fruit swelling and pressure increase suddenly, and the pericarp split longitudinally. 2, related to the characteristics of the variety, the pericarp is not strong, such as Fujiminori grape pericarp is large and thin, which is easy to crack; the pericarp and pulp of varieties such as Brown seedless stick tightly together, and when the pulp increases, part of the pericarp is compacted and stretched to cause cracks; the grains and grains are squeezed too tightly, as is the case with Kangtai, and it is easy to crack when the swelling pressure is increased. 3. Due to the reasons of cultivation and management, diseases occurred in the process of grape growth, the leaves were wilted or damaged, and the ratio of leaf to fruit was too small, and the transpiration of leaves was weak, which led to a large amount of water had to be transported to the fruit, resulting in fruit cracking.
