Scanning microscopic analysis cell structure of 8 apple cultivars was carried out. For each variety, skin and flesh, cut and broken preparation was made to research microstructure of apple tissue. The results revealed differences in shape, cell size, thickness of cellular wall, distribution and size intracellular spaces and other fruit texture features of apple varieties tissue. In microscopic picture some varieties of apple were found. Some dependence between structure of apple tissue and sensory assessment of fruit was found too.

In this work the dynamics of colour changes was examined in apple slices during convectional drying. The drying was carried out at a temperature of 60°C until 10% of moisture content was obtained. During drying, the colour of the tested apples was measured using the L*a*b* system. Three different apple varieties were used for tests (Ligol, Champion and Alwa). Each sample was divided into three parts – the first was dried without preliminary processing, the second was blanched in water at 98°C for 2 min, and the third was blanched in water (98°C, 2 min) with sugar and citric acid added. Based on the results obtained, the rate of changes in all colour parameters during the process was determined. It was concluded that the dynamics of colour changes depends on the variety. The type of preliminary treatment had an influence on the dynamics of colour changes mainly in the case of Ligol variety.

The hawthorn spider mite (Tetranychus viennensis Zacher) and two-spotted spider mite (Tetranychus urticae Koch) accepted all 13 apple cultivars given to them. The hawthorn spider mite most rapidly began permanent feeding on the apple cultivars: Priam, Witos, Pionier and Freedom. The two-spotted spider mite behaved similarly, but on the cultivars Romus, Primula, Florina and Lodel. The time of permanent feeding for the both spider mile species varied much, ranging from 1 min 8 sec to 21 min and 42 sec.

Productivity of plants is determined by multiple factors that directly affect one another, therefore yield variability may be high and difficult to predict. Most often, however, a lower crop yield is achieved in the notillage system than in the ploughing system. An exact field experiment was undertaken to determine the yield and chemical composition of pea seeds sown under conditions of: 1) conventional tillage – CT (shallow ploughing and harrowing after the harvest of previous crop, pre-winter ploughing in winter); 2) reduced tillage – RT (stubble cultivator after the harvest of previous crop); and 3) herbicide tillage – HT (only glyphosate after the harvest of previous crop). A cultivation unit was applied on all plots in the springtime. Pea seed yield was higher by 14.1% in the CT than in the RT system and by 50.5% than in the HT system. The CT system was increasing the plant number m–2, number of pods and seeds m–2, seed mass per plant, and 1000 seeds mass, compared to the other systems. Protein content of seeds was at a similar level in all analyzed tillage systems, but was affected by the study year. In turn, the mineral composition of seeds was determined by both tillage system and study year. The seeds harvested from CT plots contained more phosphorus and iron, those from RT plots – more calcium and zinc, whereas those from HT plots – more phytate-P, potassium, magnesium, and copper, compared to the seeds from the other plots.

Twenty two scab-resistant apple cultivars, harvested in the 2007 and 2008 seasons, were analysed for phenolic compounds content and polyphenol oxidase (PPO) activity. Tyrosine content was determined in the raw juices of five selected cultivars. The results showed substantial differences in the composition between the investigated apple cultivars, particularly in the phenolic compounds contents. Their total polyphenol content ranged from 161.9 to 882.4 mg/kg f.w., with hydroxycinnamic acids as the main phenolic compounds. The level of PPO activity ranged from 5 to 240 U/g f.w. Almost half of the 22 cultivars show PPO activity below 50 U/g f.w. 'Angold', 'Selena' and 'Gold Milenium' showed the highest PPO activity; between 125-133 U/g f.w. 'Rebella', 'Sampion', 'Topaz', 'Rewena', 'Enterprise' and 'Gerlinde' showed the lowest PPO activity. Statistical analysis showed no correlation between PPO activity and total polyphenol content or hydroxycinnamic acids. No correlation can be confirmed between PPO activity and tyrosine content.

The aim of the study was to determine the polyphenol profile and antioxidant activity of eleven apple cultivars harvested from an orchard in Garlica Murowana (Poland). 'Antonowka', 'Red Boskoop', and 'Winter Goldparmine' had the highest antioxidant properties of all the cultivars studied. The profile of polyphenols was different in individual cultivars. In all the studied fruits, though, it was shown that (-)epicatechin, procyanidin B2, and chlorogenic acid essentially outnumbered other compounds quantitatively. The apple cultivars recommended for manufacturing apple preserves are presented.
