Dormancy is a beneficial biological adaptation mechanism of deciduous fruit trees such as peaches, and is also a growth and development process of the peach trees, and dormancy and release of the peach trees are regulated by intrinsic cell changes of the peach trees and the external environment. Intrinsic changes are mainly focused on hormonal regulation, including endogenous hormones such as auxin, gibberellin, cytokinin, abscisic acid and the like and synergistic regulation between the hormones. It has also been confirmed by studies that the initiation, termination and change of dormancy stage are regulated by hormones, so that the content change of endogenous hormones during dormancy of peach branches is measured, and key substances for judging dormancy progress of peach trees are found, which plays a vital role in artificial regulation of dormancy, especially in peach tree facility cultivation.

The sampling method for measuring endogenous hormone in dormancy period of peach branches comprises the following steps: under the natural overwintering condition, sampling 1 time every 1 week from the dormancy induction period to the dormancy release period of the peach tree, selecting 10 annual branches with good growth and development and uniform thickness for each variety, removing dormancy buds, cleaning with ultrapure water for 3 times, sucking off the water on the surface of the branches, shearing the branches into 1-2mm wafers by pruning shears, quick-freezing with liquid nitrogen, grinding into powder, and testing. Because the endogenous hormone of the branches is continuously changed during dormancy, the branches need to be quickly frozen by liquid nitrogen after being collected, otherwise, the measurement result is affected, but the problems of complex operation, time consumption, labor consumption and the like exist in the process of shearing the branches into 1-2mm wafers by pruning shears, the problems are mainly represented by the fact that one branch needs to be sheared into the wafers by the pruning shears, the time consumption and the labor consumption are very high, the sample collection process of the branches is greatly limited, and the test result is affected by the fact that the sample processing time difference easily occurs, therefore, the sampling device for measuring the endogenous hormone of the peach branches is provided.
