Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As described in the background art, the prior art has the defects, and in order to solve the technical problems, the application provides a measurement method for the thickness of capsicum pericarp.
In an exemplary embodiment of the present application, as shown in fig. 1, a method for measuring the thickness of capsicum pericarp includes the first steps of: material selection
Harvesting fresh hot pepper fruits in green and ripe stage, collecting 10-15 fruits from each material, and cutting 1cm×1cm square from the middle part of the fruits for later use.
