Variability of quantitative traits in regenerants Vaccinium corymbosum in vitro under influence of indolebutyric acid and phytosteroids
Abstract
Results of the comparative analysis of variability of 8 quantitative traits at regenerants of Northland and Patriot cultivars of highbush blueberry in vitro on nutrient, agarized mediums for rooting, with organic compounds, on macro- and micro- salt basis of / WPM differing on composition of auxins in 9 variants of experience are given presented. Distinctions on variability of analyzed traits depending on phytohormonal structure of the medium are established. A certain regularity of variability of height and crude weight of regenerants with growth of concentration of applied phytohormones was observed. Usage of phytohormones in comparison with control more often led to reliable increase in indicators of regenerant height by 1.21.4 times, lengths of the third interstice by 1.2-1.3 times (only at Northland cultivar), the crude weight of regenerants by 1.21.4 times (only at Northland cultivar), viability of explants by 1.2-1.4 times (only at Patriot cultivar). It is established reliable (in most cases at P <0.01) influence of a genotype, phytohormonal structure of the medium and set of two factors on variability of the vast majority of analyzed traits, respectively - seven of eight traits from shares of influence of 3-30 %, all traits from shares of influence of 19-56 %, six of eight traits from shares of influence of 10-42 %.
