COMPARISON ASSESSMENT OF THE INFLUENCE OF VARIOUS TYPES OF DRUGSON THE DEVELOPMENT INDICATORS OF ROOT-BEARING SEEDLINGS OF TABLE GRAPE VARIETIES
Actual problem of viticulture is the development of progressive technology of cultivation of grape plantings guaranteeing receiving high yield, pure and safe from ecological point of view. In this regard sowing material at application of biological stimulators and regulators of growth for receiving bigger number with higher qualitative characteristics is reasonably actual and perspective. As a result of laboratory experiments on application of growth stimulating preparations on root-related grapes seedlings the data were obtained showing that, applying preparations, it was possible to receive the results surpassing control option without processing in several quality indicators 1.5 and more times. So, for example, seedling yield of root-related grape seedlings in the variants with application of the preparations» Nanosilicon « and «Beres Super Universal» on Kesha variety, made about 74.8 and 72.3 % respectively in comparison with control variant where the result made only 35.6 %. On Dekabrsky variety, identical data were obtained. Morphological indicators in both varieties on the same preparations also showed better results, however, the saplings processed by the preparation «Beres Super Universal» showed good results on the formation of the area of leaf surface of 931.52 cm2 (Dekabrsky) and 939.91 cm2 (Kesha against 395.72 and 593.74 cm2 in control variant. The preparations «Kultimar» and «Humate +7 IODINE» did not show so good results, however morphological indicators and general indicator of seedling yield were higher, than in control option without processing by preparations.
