Application of colorimetry method for establishment of features of pink and red color of flax petals
Abstract
Aim. Using the method of colorimetry, to investigate the features of the manifestation of pink color of the petals of the corolla in cultivated and wild species of flax. Methods. Colorimetric, descriptive, statistical. Results. Different colors of petals of a number of flax lines with the use of instrumental technologies are analyzed and their numerical characteristics in the channels of red, green and blue colors of the spectrum are established. The obtained numerical characteristics of color are characterized by rather small variation that allows to use this technology for reliable identification of the samples of flax differing in color of petals or other parts of a plant. Conclusions. It was found that in all genotypes of flax with pink color of the petals in numerical terms, the red color component has similar values and predominates over other color components. L. grandiflorum was found to have the highest percentage of color components, which differs significantly from other genotypes studied. A large proportion of red color was also found in the variety Rumyanets and L. pubescens. And in the pink-flowered lines of cultivated flax M-66 and LR-1-1 a uniform ratio of color components was found.
