Aim. We have researched probabilistic relations between genome size and two adaptability indices in eleven genotypes revealed in seeds germ of Deschampsia antarctica E. Desv. which has different genome size under standardized cultivation condition in vitro. Methods. We have used biochemical method for determination of flavonoid contents in plant leaves and flow cytometry analysis for determination of genome size in plant leaves. Results. Eleven genotypes of Deschampsia antarctica with different genome size have been researched by three data rows. Probabilistic scheme have been created and analyzed for all researched genotypes. Conclusions. The Deschampsia antarctica genome size or karyotype changes have been shown to have effect on its probabilistic relations with flavonoids content and leaf length. Mechanisms of such relations is required a detailed research.
Keywords: Deschampsia antarctica, genome size, leaf length, flavonoids.
Aim. The aim of this work is to research two adaptability indices (leaf length and flavonoid content and spectrum) in eleven genotypes revealed in seeds germ of Deschampsia antarctica E. Desv. in standardized cultivation condition in vitro. Then these adaptability indices would compare with the same for native populations. Methods. We have used biochemical method for determination of flavonoid contents in plant leaves, HPLC method for research of flavonoid spectrum in plant leaves. Results. Heterogeneity of leaf length and flavonoid content has been shown. Both parameters difference have been detected in comparison with native populations. Flavonoid spectrum has no difference in comparison with native populations. Conclusions. Deschampsia antarctica genotypes under standardized cultivation condition in vitro have had longer leaves than plants in nature populations. Length of the leaves was varied depending on karyotype of corresponding genotype. Cultivated plants have had flavonoid spectrum similar to the same plants in nature. This fact allows to assume plants in vitro possible producent of secondary metabolites.
