Research advances in non-destructive detection methods of seed vigor

Seeds are the most fundamental means of agriculture production, and their vitality will directly affect the production and development of agriculture. The detection methods of seed vigor are mainly divided into two categories:non-destructive testing and lossy testing. With advantages of no damage to seed samples, high detection efficiency, online detection, good repeatability and less experimentation pollution, non-destructive seed vigor testing methods include near-infrared spectroscopy, hyperspectral detection, electronic nose detection, and machine vision detection. Based on the development status of non-destructive testing technology for seed vigor at home and abroad, this paper comprehensively reviews methods, techniques and detection results of non-destructive testing of seed vigor, and summarizes the characteristics, application status, research progress, advantages and disadvantages in practical application, summarizes the current methods of non-destructive testing of seed vigor at home and abroad, and forecasts the development trend.
