Abstract

See full text

The present invention discloses a CIELAB color space-based quantitative testing and analysis method for rice seed viability, and the method comprises removing husks on surfaces of rice seeds, soaking and imbibing the rice seeds without the husks removed, staining the rice seeds by using a TTC staining solution, and longitudinally cutting the rice seeds along embryos; converting the longitudinal section image of the rice seed from an RGB color space to a CIELAB color space, and calculating L value, a value and b value per unit area of the rice embryo as a staining intensity per unit area, and converting the staining intensity into a rice seed viability score according to a pre-established conversion model of the staining intensity and the rice seed viability score. According to the present invention, a reference result can be provided for the rapid, accurate and objective evaluation of the seed viability.
