SAPROPEL IN THE TECHNOLOGY OF PRODUCTION OF SEA-BUCKTHORN SEEDLINGS
Keywords:sapropel, sea buckthorn, green cuttings, rhizogenesis, root formation stimulator, seedlings
AbstractThe biological effects of sapropel in the technology of growing sea- buckthorn seedlings are studied. It is established that the rooting of green cuttings of the studied varieties on the sapropelic substrate is higher compared to the classic version – peat + sand by 2,0 – 31,3%. It is revealed that the composition of the substrate, the use of the root formation stimulator and varietal characteristics of culture influence the further development of plants grown by the non-transplant method at the place of green cuttings rooting. The most positive effect on the quality of the sea-buckthorn planting material is obtained on the substrate of peat + sand. It is recommended to use the sapropel-based substrate for rooting of the sea-buckthorn stem cuttings in the production conditions, and to apply the transplant method for seedlings further growing.
