7. Translate from Russian into English:

1) Яблоки стали возделывать в Месопотамии. В настоящее время около 2500 сортов яблок выращивают в США, и 7500 сортов яблок выращивают во всем мире.

2) Особенно высокое содержание витамина С в яблоках; яблоки также обеспечивают человека витамином А, который служит мощным антиоксидантом, помогает противостоять инфекциям, очистить организм от свободных радикалов, которые вызывают болезнь.

3) Яблоки являются одним из самых загрязненных пестицидами продуктов сельскохозяйственного производства.

4) Исследования также указывают на связь между употреблением в пищу яблок и сниженным риском заболеваемости раком из-за высокого содержания флавоноидов в них.

5) Яблоки, оказывается, содержат больше антиоксидантов, чем любой другой продукт, причем в кожуре еще больше, чем в мякоти.

Text 3. Evaluation of ‘Sun Protect’ in protecting apples (Malus × domestica Borkh.) against sunburn

Mature trees of the apple cv. Granny Smith grafted onto M9 rootstock were chosen for the study. The trees were 12 years old, planted in a randomized complete block design with 3.5 × 4 m spacing and trained to a palmette system. 25 trees were used for each treatment (five replications × five trees). The orchard was managed with standard horticultural practices regarding irrigation, pruning, and fertilization.

Apple trees were sprayed with 1 l/ha ‘Sun Protect’ (Compo-Expert) for two successive years (2013 and 2014) in an apple orchard located in northern Greece on the following dates: June 19, June 26, August 2, August 9 and August 16. Control trees were not sprayed. Collected parameters showed the meteorological data during apple fruit development and maturation for the growing sea­sons 2013 and 2014.

Forty apples were collected from each treatment at the stage of their commercial maturity. Fruits were transported immediately to the laboratory for analyses. Fruits were weighted and evaluated for colour, soluble solids, acidity, and flesh firmness. In addition, total phenol content and antioxidant activity were determined. Finally, fruits from the untreated control and from the treated trees were placed into a common cooling chamber quality parameters were determined.

Photosynthetic parameters such as photosyn­thetic rate, transpiration and stomatal conductance were measured with the LCi portable gas exchange system (ADC BioScientific Ltd., Herts, UK) from 11.00 am till 13.00 pm at harvest (mid-September). Instantaneous water use efficiency was estimated as the ratio of photosynthetic rate to transpiration rate.

Statistical analysis. All parameters were com­pared separately for each year and data were subjected to one-way ANOVA using the SPSS 17.0 for Windows statistical package (SPSS, Chicago, USA). Comparison among the means to determine statistical differences was performed using Fischer’s F-test (P ≤ 0.05).
