Abstract

Biologically active compounds, sugars, acids and antioxidants are key-important ingredients of healthy tomato food. Objective of the study is to investigate if specific industrial bioeffector products are improving the taste and some quality parameters of tomato fruits and how those results are appearing in pots and among organic field conditions? Spore-forming industrial Bacillus amyloliquefaciens FZB42 (RhizoVital) as single inoculums and combinations either with other Bacillus strains (Biorex-1), or with N2-fixing-siderophore-producing strains (Biorex-2) were applied on Solanum lycopersicon Mill. var. Mobil test plant. Soil microbial counts, phosphorus availability and fruit quality, such as total soluble solids (TSS), content of some essential organic acids (citric-, maleic) and sugars (glucose, fructose) were assessed. The results found, that single industrial inoculums of FZB42 product had positive effect on P-availability and fruit quality in the pots, combinations of other biofertilizers, however, did not give additional results. Fruit quality parameters, TSS content, soluble sugars and organic acids were significantly improved (p<0.05) at both experimental conditions. Such better fruit taste was correlated significantly by the most probable number (MPN) total microbial counts with greater positive values in pot experiment, compared with more variable environmental field condition. The recommendation of using such bioeffector products is supported by the positive interrelation among measured soil characteristics and inside healthy quality parameters of organically grown tomato fruits.
