We have developed a rapid shoot multiplication procedure for in vitro propagation of blue honeysuckle (Lonicera kamtschatica [Sevast.] Pojark). Shoot tips of two genotypes 20/1 and Altaj were successfully established in vitro and micropropagated on the Murashige and Skoog (MS) based media containing different concentrations of 6-benzylaminopurine (BAP). Multiplication rates varied depending on the genotype and concentration of BAP. The highest multiplication rate was obtained for the genotype 20/1 that produced 10.5 ± 0.7 shoots (longer than 10 mm) on the MS medium containing 2 mg/l BAP. The lowest multiplication rate was...

In the years 2005 and 2006 the effect of site conditions, yellow and purple fleshed varieties and mineral fertilization on the content of total polyphenols (TP) in potato tubers was investigated. In both years significantly the highest TP content (by 5.7 to 56.3% higher than in other localities) was determined at the Stachy locality; we ascribe it to apparently lower temperatures in the vegetation period at this locality of higher altitude. In the purple flesh Valfi variety TP content higher by 74 to 141% was recorded in average of both years, in comparison to yellow flesh varieties. In the group of eight yellow flesh varieties the highest TP content...

Wild service tree belongs among rare woody plants tolerant to higher temperatures and low soil humidity. There are available data from analyses of 34 wild service tree localities in Slovakia. The majority of analyzed localities (70%) were on south-exposed stands (SE, S, SW); 97% of these were in altitudes up to 600 m. Wild service tree prefers biotopes of the oak-hornbeam forests. The highest frequency of this woody plant was found in group of forest site types Fageto-Quercetum. According to altitudinal vegetation stages, the majority of stands (85%) were in the 3rd and 2nd vegetation stage, where potential evapotranspiration...

A relationship between the verdure system and land use planning of a small town

M. Jebavý

Hort. Sci. (Prague), 2007, 34(4):152-158 | DOI: 10.17221/1895-HORTSCI  

Small towns are defined as towns with the population not exceeding 15,000 (20,000) residents. They are organisms that can be embraced visually, mostly with the clearly demarcated area. Residents know their small town very well, the majority of buildings and structures is constructed at a reasonable scale and architectonic dominants allow easy orientation. Verdure in a small town is either a separate functional space (park, landscaped area, forest, scattered green vegetation) or it is associated with another function (residential green spaces, green spaces of housing estates, line verdure, verdure of self-retained areas - sports grounds, cemeteries,...

Citrus Greening Disease - A major cause of citrus decline in the world: A Review

Hort. Sci. (Prague), 2007, 34(4):159-166 | DOI: 10.17221/1897-HORTSCI  

Citrus Greening Disease (CGD) was critically reviewed with respect to its history, origin, symptomatology, host range, pathogenic association, identification and detection, transmission and management. It is evident that the citrus disease has emerged as a potential serious threat to citrus production in all the citrus growing countries of the world including Pakistan. It is has been proved that in Pakistan the greening disease is the major cause of citrus decline; hence it is necessary to formulate definite planning and strategies.
