Determination of the correlation between the accumulation of pigments and natural rubber in Tau-saghyz

Abstract

Ab ract. Natural rubber is a valuable polymer used in a wide variety of indu ries, from tire manufactur-ing to medical products and applications in the food indu ry. The tau-sagyz rubber plant ( Scozonera tau-saghyz Lipcsh et Bosse) is one of the few plants in the world that can be used in the production of natural rubber when cultivated in culture. To increase the productivity of plants, it is necessary to e ablish factors affecting the biosynthesis of natural rubber. In our udies, the level of pigments (chlorophyll–a, b, carot-enoids) was chosen as a factor that may have a positive effect on the accumulation of rubber in the roots of S. tau-saghyz. For this purpose, samples (leaves, roots) were taken from 3 groups of plants (north, south, ea ) in the Karatau mountains of the Kurman-Tas range. The extraction of pigments from leaf samples was carried out with acetone, and the extraction of rubber from the roots was carried out with hexane. The obtained data on the content of pigments and rubber in the samples were ati ically processed using the t-te and Pearson correlation analysis. As a result, a ati ical difference in the values of pigment accumulation in leaves and rubber in roots between the 3 udied groups of plants is shown. On the other hand, a very low level of correlation was found between the accumulation of pigments in the leaves and rubber in the roots in all three groups. The obtained results reliably showed that the level of pigment accumulation in the leaves does not affect the accumulation of rubber in the roots of Tau-sagyz.
