Abstract

The article examines the effect produced by the preplant inoculation of potato tubers with Bacillus subtilis on biochemical processes occurring in the tubers of a new crop during the postharvest period at different storage periods. The content of malondialdehyde in tubers treated with strains 10-4 and 26D decreased by 15.5 and 35.5% and by 14.9 and 13.6% relative to the control after one and six months, respectively. The proline content in tubers pretreated with strain 10-4 differed insignificantly from the control in both storage periods, while in the case of strain 26D, it was lower than the control by 14.7 and 26.3%. First, the activity of protective proteins in treated tubers decreased relative to the control; then, the activity of trypsin inhibitors in tubers was found to significantly exceed that in tubers stored for a short time. The protein content of pretreated tubers was initially higher than that of the control; then, it was either at the same level (strain 26D) or 15% lower than the control (strain 10-4). The content of ascorbic acid in tubers pretreated with strain 10-4 exceeded that of the control by 16.1 and 17.9% after one and six months of storage, respectively, whereas in the case of strain 26D, no difference from the control was noted. The amount of reducing sugars was 39.4% lower than the control after one and six months of storage (strain 10-4) and 35.6% after six months of storage (strain 26D). The pretreatment with strains 10-4 and 26D positively affected the main biochemical parameters of tubers during long-term storage, providing a protective effect and preserving the biological value of produce.
