FEATURES OF MINERAL WASTE AND THE EXPEDIENCY OF THEIR USE IN THE FOR-MATION OF COMPLEX COMPOSTS
DescriptionThis article summarizes the results of the study of physical, chemical and biological characteristics of mineral waste; it analyzes the specific features of its behavior when applied to the soil in pure form and in complex compost; the possibility of using some of them as an ameliorant for improving the fertility of soil common in the steppe zone of the region

Description
The article discusses the features of the accumulation of essential oil in the collection samples of Oregano studied in the foothill zone of the Crimea. The range of variability of the mass fraction of essential oil of Origanum vulgare (from trace amounts to 0.53% of the bone dry weight). We have revealed that the greatest amount of essential oil accumulates in the inflorescences during the flowering phase

Description
The article is dedicated to the features of the correlations between the indicators of shoot and root growth ability of grape cuttings varieties of Moldova and Vostorg of different lengths, under the influence of the processing them with Norwegian growth regulator - Radix plus. We have found that in the control variants on both varieties there are fairly close correlation connections between the number of shoots, their length and the degree of blooming buds. However, in the advanced options the character of the relationship between these parameters depends on the varietal characteristics manifested in the potential root activity cuttings. For Moldova cuttings which are characterized by high root activity, the use of Radix plus led to some strengthening of the correlations, and for Vostorg (with the weak activity of rooting of cuttings) - to decreasing of the correlations. This fact may indicate that the negative effects of growth regulators on the activity of endogenous hormones in the cuttings of Vostorg varieties, which explains the decrease of rooting of longer cuttings. Processing the cuttings of Moldova with Radix plus led to increasing in the frequency and extension of the correlations between shoot and root growth ability of cuttings. For Vostorg, on the contrary, the use of Radix plus led to the weakening of these connections. The reason for this phenomenon, as is the case with figures of shoot growth ability may be a change in the activity of the endogenous phytohormone influenced by exogenous auxin. Character of correlations identified between indicators of root growth ability of cuttings shows that rooting depends primarily on the hormonal activity of cuttings, number of roots - on cuttings plastic substances, and the yield of cuttings with 3 roots and more - on both of these points

Description
The research results on regeneration activity of wilding cuttings of phylloxeraresistant varieties of grapes influenced by heteroauxin treatment are analysed in the article. The preliminary studies were held in All-Russian research institute of viticulture and wine-making of Ya.I. Potapenko using cuttings of 3 grape varieties – Berlandieri x Riparia Cober 5bb, Riparia x Rupestris 101-14 and Berlandieri x Riparia CO-4. The cuttings were soaked during 48 hours in 0,005 % heteroauxin and were implanted in sand in adjustable conditions of temperature, humidity and aeration. In 2012-2013 experiments were continued in Kuban State Agrarian University. The varieties Gravesak, RSB and Berlandieri x Riparia Teleki 5C were added to the experiment. Three-items buds were shooted in damp steamed sawdust in a film hothouse. In preliminary researches application of heteroauxin has allowed to increase root-growing by 20,3-40,0 %. The greatest increase of root-growing (40 %) was observed on variety СО-4, that is characterized by the weakest potential rhizogenesis activity, and the least (20,3 %) on control variety Cober 5 bb. Next researches show that treatment of cuttings basal ends by 0,01 % heteroauxin activated their regeneration process, that was expressed in: increase in sprouts length – variety 5 C, 101-14 and Gravesak by 23,1- 157,6 %; increasing of cuttings root-growing from 16,7 % on variety 5C to 60,0 % on variety Cober 5 bb, the quantity of cuttings with not fewer of 3 roots from accordingly 13,0 % to 54,7 %; increasing of roots from 0,7 on variety СО-4 to 2,7 on variety 101-14 or in 1,7-2,7 times. The application of heteroauxin on variety RSB did not show positive results, because of the variety peculiarities

Description
The article presents the results of the research on the effect of processing cuttings grapes Moldova and Bianca by a growth regulator called Stimolant 66f (Stimolante 66f) on their regenerative properties, the yield and quality of seedlings. In Moldova grade, we tested three concentrations of the drug - 0.001; 0.01 and 0.1% and grade Bianca - five - - 0.001; 0.005; 0.01; 0.05 and 0.1%, compared to treatment with IAA (standard) or without treatment (control). It was found, that both types of processing cuttings with IAA led to the inhibition of blooming buds. Application of Stimolanta to both varieties accelerated blooming buds, and to the greatest extent on grade Bianca. On the variety Moldova, the processing cuttings with heteroauxin and Stimolant at 0.01 and 0.1% had an inhibitory effect on the growth of shoots, which survived to the end of the experiment. On the variety of Bianca, both the IAA and Stimolant at all concentrations of working solution contributed to a significant increase the length of the shoots. At grade Moldova, basal ends of cuttings treatment for 24 hours in solutions of Stimolanta at 0.01 and 0.1% concentration had the root-growing ability stimulated, enhanced the yield and quality of seedlings. In grade Bianca, better rooting of cuttings with 3 or more roots was observed in the variant of "Stimolant - 0.05%", and a greater number of roots were produced in the version of "Stimolant - 0.1%." In cuttings of varieties ofMoldova, Stimolant showed better results than the IAA in optimal concentrations, and grade Bianca had about the same results
