From a total number of 62 apple samples included in this study, 42 cultivars or selections were evaluated after storing in standard conditions, and the remaining 20 in ultra low oxygen (ULO) storing conditions. The top leader regarding total taste quality was cv. Meteor, which obtained the highest total scoring value, and also in the mean sequence it was the number one cultivar. In the following position with regard to the total fruit quality was cv. King Jonagold. In a decreasing sequence of total fruit quality, the cultivars were classified in the following order: Rosabel, Andera, Angold, Berta and Meteor stored in ULO. In the case of fruit taste...

In this study, in vitro slow growth storage was investigated in four cultivars of two Sicilian (Southern Italy) plum species (Prunus domestica L. and Prunus cerasifera Ehrh. - two genotypes each). Established shoot cultures were preserved at 4°C in the dark in a Murashige and Skoog basal medium containing one of two different concentrations of sucrose (20 and 30 g/l) and with or without growth regulators. We tested the effects of cold storage, genotype and media on survival and re-growth capacity of explants after 3, 6, 9 and 12 months of storage. Effective minimal growth under cold conditions occurred in all four genotypes....

In 2011-2013, a study on the crossing compatibility and the setting of fruit in distant hybridization within the genus Prunus, among the species P. armeniaca L. (apricot), P. salicina Lindl. (Japanese plum), P. cerasifera Ehrh. (myrobalan plum) and the hybrids P. salicina × P. cerasifera was conducted at the Institute of Horticulture in Skierniewice, Poland. The percentage of fruit set depended on the direction of pollination of the crossed species. Most fruits were obtained by crossing P. salicina × P. armeniaca and P. salicina × P. cerasifera. The largest...

The diversity of parental genotypes has a major impact on the progress of plant breeding. This study assessed phenotypic biodiversity of 91 strawberry genotypes in the core collection of the Research Institute of Horticulture in Skierniewice, Poland, using multivariate statistical methods. The assessment was carried out from 2008 through 2010 for 13 traits describing plant growth vigour, flowering and fruit ripening times, fruit yield, fruit appearance and quality (position of the calyx in relation to the surface of the fruit, fruit size and firmness, skin and flesh colour, fruit glossiness, intensity of the fruit's aroma and sweetness), as well as...

Phosphorus (P) is essential for crop production. Adequate application P rate is critical for enhancing productivity and profitability of snap bean (Phaseolus vulgaris L.). The goal of this study was to optimize P application rate for commercial snap bean production in south Florida. Six trials were conducted on sandy soils and muck soils in Hendry County and Palm Beach County, Florida, USA. Before planting cv. Caprice snap bean, plots were fertilized with different P application rates in the form of triple superphosphate (0-45-0). An increase in P2O5 application rates up to 134 kg/ha P2O5 significantly...

Although plants of Vaccinium genus have not been cultivated on a large scale in the Czech Republic, there is a potential for commercial lingonberry production in some mountain regions. The purpose of this study was to develop an efficient in vitro system for a quick multiplication of lingonberry cvs Koralle, Linnea, and Runo Bielawskie. McCown woody plant medium (WPM), Anderson's rhododendron medium (AN) and half-strength Murashige and Skoog medium (half-MS) containing cytokinin zeatin in concentrations 0.5, 1 or 2 mg/l were tested for repeated subcultures. The number of newly formed shoots varied with the cultivar, medium tested and concentration...
