Tree growth, flowering, yield and fruit quality of Prunus armeniaca L. cv. Ninfa grafted on peach cv. Nemaguard [Prunus persica (L.) Batsch] and cv. Real Fino apricot (Prunus armeniaca L.) as rootstocks were analysed in experimental orchard under organic and conventional management systems. The study was performed during 2012-2013 in the province of Seville (SW Spain). Cv. Nemaguard rootstock had larger cross-sectional areas of the trunk (TCSA), higher yields, began flowering earlier and lasted 2-4 days more. The organic management resulted in lower values of TCSA and yield, and flowering was delayed and shortened....

During 2009-2011, regular captures of Cacopsylla pyri, C. pyrisuga and C. pyricola in four pear orchards (one conventional orchard, one integrated pest management (IPM) orchard, two organic orchards) were conducted in the Czech Republic. Polymerase chain reaction (PCR) tests were performed on psyllids captured from the orchards with the highest occurrence of these insects. The DNA extracted from pairs of psyllid individuals was analysed by nested PCR (R16F2n/R2-fU5/rU3) and restriction fragment length polymorphism method (RFLP) (RsaI, BfmI). Two C. pyri individuals captured on 11/05/2011 in the IPM orchard...

Ascorbate metabolism is an essential procedure for all plant cells that plays important roles in several physiological processes such as plant development and reactive oxygen species detoxification. To shed more light on ascorbate metabolism in certain organs of tomato plants, we performed a detailed compartmentalized analysis of ascorbate concentration, ascorbate peroxidase/dehydroascorbate reductase enzyme activities and transcript accumulation of genes related to ascorbate metabolism. Our results showed higher level of ascorbate concentration and ascorbate peroxidase and dehydroascorbate reductase activities in young leaves and shoot tips, while...

Caraway fruits contain essential oils that give caraway its characteristic aroma. This paper evaluates quantity and composition of the essential oil from the annual caraway grown in different production areas of Serbia. Experiments were conducted in three production areas: Banat, Bačka and Srem, during two years. The fruits contained 3.95% of oil on average. The highest content of essential oil was obtained in the production area of Banat, a part of Serbia where environmental conditions are very favourable for cultivation of medicinal plants. Weather conditions have not a significant influence on the content of essential oil in caraway fruits. However,...

Investigations of productivity and biochemical valueof dill cvs Moravan, Szmaragd, Common, Mammoth and parsley cvs Moss Curled, Astra, Festival, Gigant d'Italiawere estimated. Dill cv. Commonwas the highest, 62.3 cm, and the most productive, up to 29.1 t/ha. The analyses of biochemical compounds showed that cv. Szmaragd accumulated significantly highest amount of the dry matter (14.7%) and total sugar (3.07%). Dill cvs Moravan and Common were close as to the ability for chlorophyll accumulation (2.04-2.02 mg/g). The highest amount of essential oils was estimated in the cvs Szmaragd and Mammoth, 0.17 and 0.18%, respectively. Investigations of parsley...

Hort. Sci. (Prague), 2014, 41(3):138-146 | DOI: 10.17221/208/2013-HORTSCI  

Field experiments were conducted in two seasons to investigate growth, physiology and yield responses of cabbage (Brassica oleracea L. cvs Pennant and Rio Grande) to deficit irrigation. In 2012 season, 50% of crop evapotranspiration (ETc) irrigation temporarily decreased plant size, reduced leaf area, fresh weight, relative water content, specific leaf area and gas exchange during late development, and decreased head fresh weight, size, marketable and total yield. Deficit irrigation at 75% ETc had little influence on plant growth and physiology, but it still reduced both marketable and total yield. In 2013 season, 75% ETc irrigation had little...

Hort. Sci. (Prague), 2014, 41(3):147-151 | DOI: 10.17221/17/2014-HORTSCI  

Of the grapevines grown in the Nordic countries, cv. Zilga, bred in Latvia, has proven to be very winter resistant and fast-maturing, and produces abundant harvests. In Finland, it is grown as horticultural and agricultural plant unprotected on open land even at 63 degrees latitude. In Southern Finland (60°24'10''N, 25°01'45''E), the growth cycle of cv. Zilga from bud break to harvest lasted 116 days and to leaf fall 125 days. At the beginning of the harvest, the total sugar content was 19°Bx. Tracking the phenology of the growth cycle and the environmental conditions of the growth site shows that cv. Zilga is well placed to make use of the high ambient...
