The objective of the research was to observe the influence of A.D. type bio-phyto-modulators uponseed germination and plant biology. The biological material subject to analysis was represented by Coralvariety of tomato and hybrid Blondy F1 pepper seeds. As part of this experiment DEA A.D. type biophyto-modulators has been used. For germination rhythm determination was used one version in 4replications with 15 seeds each, which was attached a DEA type device and one control version, with nodevice attached. In the fourth day from seeding in variant with the tomatoes and DEA, the first plantsappeared, and until the sixth day all of the 15 seeds were germinated. The germination for “witness”variant began as late as day six and finished in tenth day. For the pepper seeds the sample with DEAbegan germination in the eighth day and ended in twelfth day while “the witness” began germinationin the twelfth day and ended in the fifteenth. We can see that in both cases where was located the DEAtype device germination occurred faster than normal germination time 6-8 days for tomatoes and 10-14 days for peppers. Using AD type bio-phyto-modulators brought a beneficial contribution increasinggermination speed for both species.
