Analysis of variability of quantitative traits at regenerants of high-bush blueberry varieties <i>in vitro</i> under different mode of lighting
There are presented the results of comparative analysis of variability of eight bio-production parameters in vitro at Brigitta and Northland high-bush blueberry regenerates under conditions of illumination by luminescent lamps and original device, based on light-emitting diodes. It were observed excess by chlorophyll ‘a’ maintenance in 1.64 and 2.53 times; by chlorophyll b maintenance - in 1.92 and 2.75 times; by carotenoids - in 1.38 and 2.13 times, accordingly to varieties investigated. The tendency to increase in reproduction factors for each of analyzed varieties is established.
