Humic products are a highly concentrated mixture of biologically active substances isolated from the ecologically pure raw materials of natural origin. Under their influence in the plant organism changes the permeability of cell membranes, increases the activity of enzymes and the rate of physiological and biochemical processes, increases plant resistance to unfavourable factors and stress. Studies on the effect of humic substances on the ecological-physiological characteristics of saplings of grapes in the city of Orenburg was conducted on the basis of the Orenburg experimental station of horticulture and viticulture. The object of study — woody cuttings of three cultivars of grape — Memory Dombkowski, Aleshenkin Gift and agate Donskoy. In experience used humic preparations: humate +7 elements (K, Cu, Mn, Zn, Mo, Co, B, Fe), calcium humate and magnesium humate. Before planting the cuttings treated with solutions of humic preparations, then stood in televator to the formation of callus and planted in pots. After rooting, every ten days plants were watered with solutions of humates. The results of these studies showed that: 1) pre-treatment of cuttings of grapes solutions of humates had a positive effect on the activity of callosobruchus studied varieties. Maximum positive effect was obtained in variants with humate calcium humate and magnesium; 2) humate calcium increases the number of adventitious roots and improves their growth in all tested grape varieties; 3) preparation “ humate + 7 elements” accelerates the process of shoots in cuttings and contributes to better development of the aerial organs of seedlings of grapes; 4) Application of humic preparations at cultivation of saplings of grapes in the city of Orenburg significantly improves the quality of planting material.Key words: grapes, humic preparations, released varieties, seedlings, Orenburg.
