Stress induced by soil contamination with heavy metals and their effects on some biomarkers and DNA damage in maize plants at the vicinity of Ferronikel smelter in Drenas, Kosovo.

The Ferronikel smelter in Drenas is one of the main industrial areas in the Kosovo and pollution by heavy metals causes serious threat for all living organisms on this area. The objective of this study was to determine the concentration of some heavy metals (Fe, Cu, Mn, Cr, Cd, Ni and Pb) in agricultural soils and in maize plants, and their potential toxic effects on this plant through some sensitive biochemical and molecular markers. Maize seedlings growth in nine soil samples from different locations of this area.

Cryopreservation of shoot apices and callus cultures of globe artichoke using vitrification method.

Background: Cryogenic cooling became a crucial tool for the storage of heterozygous plants such as globe artichoke. This study was carried out to optimize a reliable method for in vitro cryopreservation of shoot apices and callus cultures of globe artichoke using dimethylsulfoxide (DMSO) and Plant Vitrification Solutions 2 (PVS2) as cryoprotectant solutions. Shoot apices were exposed to DMSO or PVS2 for 20, 40, 60, and 80 min prior to plunge in liquid nitrogen (LN).

Micropropagation and in vitro conservation of the rare and threatened plants Ramonda serbica and Ramonda nathaliae.

Ramonda serbica and Ramonda nathaliae are rare and endemo relict plant species from Balkan Peninsula. An efficient micro propagation and in vitro conservation method via direct and indirect organogenesis from seed and leaf explants, respectively, was established in this study. The seed of both Ramonda species were collected from different populations in Kosovo, and were germinated in nutrient media JG-B without any phytohormone.
