SUSTAINABILITY OF MODERN VARIETIES AND HYBRIDS OF BEETROOT TO DISEASES DURING LONG-TERM STORAGE
DescriptionFungal and bacterial diseases are the main cause of losses of beetroot during storage. Resistance to them should be regarded as an important economic value of this culture. Analyzing biennial data on the preservation and damageability of diseases during the storage of 18 samples of varieties and hybrids of beetroot grown in the Moscow region, samples were identified that have complex resistance to phomosis, gray and root rot, the most harmful diseases noted during the storage of beetroot. These are varieties Bordo 237, Bordovaya VNIIO, Dvusemyannaya TSHA, and Pablo F1 hybrid, which provide a yield of merchandise products of at least 80% and are characterized by a minimal degree of damage to the above-mentioned diseases. The above varieties and hybrids can be recommended for introduction into industrial vegetable growing and use in further breeding work as donors of resistance to diseases

Description
The results of the researches on studying of grape plantings processing influence of technical grade Viorika on its agrobiological and technological indicators are stated in the article. Experiences have been conducted in public joint-stock company "Pobeda" in Temrjuksky area in Krasnodar territory. The experience scheme included three variants in 2015: without processings (control); Farmaiodne - 0,04 %; Farmaiodne - 0,06 %; in 2016 - five variants: without processings (control); Farmaiodne - 0,04 %; Farmaiodne - 0,05 %; Farmaiodne - 0,06 %; Farmaiodne - 0,08 %. Processing of experimented plants included autumn and spring bushes washing in resting period (November-April) and spraying during the vegetation period. In 2015 spraying were conducted three times: before flowering, in a growth phase of berries, in the beginning of berries maturing phase; in 2016 the fourth spraying was added after the flowering. It is noticed, that application of Farmaiodne promotes more intensive accumulation of sugars in berries juice, acceleration of crop maturing, improvement of winematerials quality. The increasing of sprouts fruitfulness and increasing in average weight of a bunch is observed, that finally leads to authentic crop increasing in a bush and productivity. Application of Farmaiodne also has positive impact on growing processes, promoting increase in sprouts length and sometimes on thickness. According to the mixture of agrobiological and technological indicators the best results are received at the application in concentration of 0,05 % and 0,06%

Description
The results of laboratory experiments on the effect of different concentrations of SkQ3 (10- (6'- methylplastoquinonyl) decyltriphenylphosphonium) on the rate of growth of spring barley seedlings of varieties Sokol and winter wheat varieties Kalym in normal and under inadequate moisture conditions, as well as data from field experiments on the effect of pre-sowing processing SkQ3 on the morphometric indices of spring barley varieties Shhedry, hard winter wheat of the Lazurite variety and soft winter wheat of the Lydia variety are presented. As a result of laboratory experiments, an increase in the growth rate of 14-day-old seedlings grown in solutions of polyethylene glycol was shown when treating the seeds with 2.5 nM and 25 nM with SkQ3 solutions. In the field experiments on the pre-sowing treatment of SkQ3 seeds, an increase in the morphometric indices of spring barley varieties of generic Lydia soft winter wheat and hard Lazurite winter wheat has been established, as well as an increase in the yield of winter wheat of both varieties as compared to the control
