The influence of biotization on the morphophysiological parameters of regenerants of <i>Vaccinium uliginosum</i> l. at the stage of adaptation to <i>ex vitro</i> conditions

The study assessed the biotization of regenerated Vaccinium uliginosum plants (Patriot cultivar) during adaptation to ex vitro conditions. The morphophysiological state of the plants was assessed non-invasively using a 3D multispectral scanner Phenospex PlantEye F500, which made it possible to obtain objective data on changes in digital biomass, green leaf index, height, maximum height, leaf shade, leaf inclination angle, leaf area, leaf area index, projected leaf area, leaf inclination, light penetration depth, NDVI (normalized differential vegetation index), NPCI (normalized chlorophyll index), PSRI (leaf senescence index). A comparative analysis was carried out by assessing the growth rates by compiling heat maps. The relationships between microbial treatment and root growth in the model regenerated plant were revealed. The obtained values of the morphophysiological state of plants were used to assess the adaptive potential of plants, which made it possible to identify the most promising combinations of inoculants that increase plant adaptation.
