Эффекты экзогенных ауксинов на изменение количественных показателей регенерантов Vaccinium corymbosum in vitro

Abstract

Results of the comparative analysis of variability of 8 quantitative traits at regenerants of Northland and Patriot cultivars of highbush blueberry in vitroon nutrient, agarized mediums for rooting, with organic compounds, on macro - and micro - salt basis of ½ WPM differing on composition of auxins in 9 variants of experience are given in the present article. The analysis of variability of ‘root length’ at regenerants of Northland and ‘percent of rooted regenerants’ of Patriot established the effects of additivity of IBA and IAA taken in concentration of 0.2 mg per liter. The highest exit of the implanted, viable regenerants was observed on the nutrient mediums containing at the same time both of auxins – IBA and IAA – in concentration of 0.2 mg/l for Patriot cultivar, and of 0.5 mg/l for Northland. The opposite effects of the auxins, applied separately at increase of their concentration, on variability of 5 studied traits at regenerants of both investigated cultivars are established.
