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
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.
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 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.
