Rapid detection and evaluation method for mechanical injury of corn seeds

Abstract

The invention relates to the field of seed science and particularly relates to a rapid detection and evaluation method for mechanical injury of corn seeds. The rapid detection and evaluation method comprises preparation of a treating solution, pretreatment of mechanical injury detection of the seeds, developing treatment of the mechanical injury of the seeds, detection and evaluation of the mechanical injury of the seeds, quality predication of the seeds and the like. Based on the mechanical injury, starch layers of the corn seeds are exposed; when an iodine-potassium iodide solution is reacted with starch, starch iodide is formed and a blue special reaction is carried out; a developing reaction is combined with division of four corn seed mechanical injury grades to rapidly detect and evaluate the mechanical injury condition of the corn seeds; and on the basis, a seed activity correlation index fitting equation is established and is used for predicating the quality of corn sample seeds under different mechanical injury conditions. The rapid detection and evaluation method can be widely applied to the aspects including the detection of the corn seeds and the like, and provides evidences to the aspects including selection and determination of machining parameters in the production and processing of the corn seeds and the like.

Description

technical field [0001] The invention relates to the field of seed science, in particular to a method for quickly detecting and evaluating mechanical damage of corn seeds. Background technique [0002] In the production and processing of modern corn seeds, mechanical operations are widely used in the production and processing processes of harvesting, threshing, cleaning, drying, packaging, etc. If the operating parameters in the processing operation are improper, and the selection of the machine is improper, etc., the seeds will be damaged due to external mechanical forces. Mechanical damage or increased damage to the surface or inside, such as extrusion, impact, rubbing, impact and shearing of threshers. Seed mechanical damage mainly includes macroscopic damage (broken, cracked, chipped, bruised, scratched, fine cracks, etc.) and microscopic damage (internal cracks, etc.). the quality of. What deserves special attention is that some seeds are mechanically damaged, which is...

AI Technical Summary

Problems solved by technology

Of particular concern is that some seeds are mechanically damaged, which are often not easily noticed, and this damage has or will affect the viability of the seeds

In addition, mechanical damage to corn seeds will inevitably affect the storage tolerance of the seeds, reduce the normal seedling rate, etc.

[0003] For the rapid detection and evaluation of mechanical damage to corn seeds, there are currently few detection methods and there are deficiencies in the identification of mechanical damage (such as: fast green dyeing is difficult to identify small cracks on the seed surface, internal damage, etc.; X-ray machines need rich identification experience , and it is difficult to detect mechanical damage on the surface of seeds, especially coated seeds), and there is a lack of suitable evaluation methods, which are worthy of research and discussion
