The article shows the results of the impact of foliar nutrition on crop and product quality of the Grenny Smith apples. Also the impact of the agricultural practices to fruits saving ability is discussed, as well as their quality in terms of sugars, acids and vitamin C. It was found that the use of 3-fold foliar nutrition feeding with nitroammofoska impacts positively on the results of storage.
As for beneficial fauna, the most number of parasitic hymenoptera is noticed in organic orchards. The least quantity of parasitic hymenoptera can be met in conventional orchards. The characteristic feature of arthropods in conventional orchards in 2008 was the frequent occurrence and rather big number of acariphages (ladybirds of Stethorus family). The occurrence of the considerable quantity of predatory bug Campilomma and the bugs of Orius family was registered. All the enumerated species attack phytophagous mites. With the assumption of phytophagous mites population increase in organic orchards, the increase in Stetorus specimen was registered. Acariphages in ecological orchards occurred rarely. So we can suggest that predacious insect species – Stetorus, Campilomma, Orius –can serve as a certain indicator showing one or another population density of phytophagous mites in apple-tree orchards.
The Codling moth monitoring, conducted with the help of injured fruits count and mail moths capture (with pheromone traps), is given in the article.
We consider that pheromone traps reliably register the beginning of the Codling moth large flight (of each generation) at high temperature and little precipitation.
The pheromone traps efficiency decreases at rather low temperature and showers. In organic and ecological orchards low density populations of injurious mites are under control of their natural enemies.
Detoxication mechanism of protein deterioration products in heat resistant apple trees (Florina variety) under overheating is substantiated. Apple trees drought and heat resistance increase in non-irrigated orchard is obtained under over-row spacing turf-covering with naturally grown grasses
The influence of unfavorable weather factors on the vital activity of fruit-trees was shown. Peculiarities of apple-tree generative development in the connection with temperature abnormalities have been studied
There was determined the stability of new varieties of tea-hybrid roses to biotic and abiotic stressors. There was given the assessment of their decorative qualities
PECULIARITIES OF POTENTIAL REALIZATION OF FRUIT-TREES PRODUCTIVITY IN THE YEARS OF WEATHER ANOMALIES
There was shown the influence of unfavorable climatic factors on the development of fruit cultivars. There were studied the peculiarities of potential realization of fruit trees productivity in connection with weather anomalies
In the article, there were determined the physiological parameters of resistance of stocked plants to in-creased pH soil. There was shown, that the resistance of apple-trees to the action of edafic stress-factors achieved in the case of their grafting on average-growing clone stock MM 106
There was determined that the heat resistance of fruit and decorate plants depends not only on their morpho-biological peculiarities but on the specific of temperature stressor revealing in corresponding years. There were selected three types of influence of high air temperature on plants on plants during summer period and three components of heat resistance respectively. There were cited possible mechanisms of plant adaptation to overheat. There were cited diagnostic criteria of their heat resistance
There was substantiated the purposefulness of introduction
in non-irrigated organic gardens of apple-trees of Kuban zone of in-row sodding of soil with naturally growing grasses providing the increase of plant resistance to abiotic stressors of summer period and as a consequence, stabilization of generative activity and the increase of fruit productivity
