The optimal composition of the working mixtures was established and the electric field strength in excilamps at which radiation occurs in the spectral bands of the photoactivity range of plants with the maximum specific power is given. The studies are carried out on the effect of additional radiation from the source in the field of photoactivity of plants when growing cluster seedlings in greenhouse conditions. It was found that all experimental plants were dominated by control samples in terms of the area of leaf surface assimilation, the weight of the aboveground and root systems.  Product Description popup.authors Aksenyuk Ivan I Popovych Halyna B popup.nrat_date 2021-03-17 Close
