Using the meteorological observations from 105 meteorological stations in Greece the values of potential evapotranspiration (PE_an) and moisture deficit (D_an) were estimated by applying the methodology of the soil water balance model sensu Thornthwaite, Their relationship with the station forest...

The existence of trees in big urban centers improves the quality of life and effectively contributes to the improvement of existence conditions in cities. The aim of this work was the research of citizens opinions about the management and growth of trees in urban centers in relation with one of the ...

The carob tree belongs to the nutrient plants and it is known since antiquity as a native plant of Greece. Its scientific name Ceratonia siliqua, originates from the Greek word "keraton" which means "horn", and which indicates the shape of its fruit. The carob tree is an evergreen, long-lived,...

Pinus brutia in Crete was sampled at four locations representing the natural distribution of the species in the island. The samples included vegetative and reproductive material. Twelve morphological and anatomical traits were measured and used to assess altitudinal and longitudinal variation of...

The introduction of new desirable traits in forestry species and their hybrids by classical breeding is time-consuming process in breeding programs. The use of biotechnology could significantly reduce the time necessary for tree improvement and offers the possibility to make new gene combinations...

Shoot tips (explants) of a mature ornamental tree, Morus alba "pendula", were established for micropropagation. Different surface sterilization treatments of the explants were tested. The best results were achieved by immersing the explants first, in a 0.5% w/v solution of sodium hypochlorite...

Mature embryos of Fraxinus excelcior L., were cultured in vitro, on different nutrient media of which the best was the 1/2 MS. Epicotyl and hypocotyls pieces were established for multiplication, on modified MS and WPM media. The best treatment was the explant establishment on MS nutrient medium...

Vegetative propagation of mature wild cherry trees, selected for wood production, was investigated by means of: (a) conventional methods (cuttings, girdling, girdled cuttings from stump and root suckers), (b) tissue culture methods (micropropagation) and (c) a combination of the above techniques by ...

Alnus glutinosa has a particular role on riparian ecosystems. Alnus glutinosa has the ability to form actinorrhizas and two different types of mycorrhizas. The improvement of micropropagation techniques is an important factor for the valorization of Alnus glutinosa and the study of symbiosis....

Agaricus bisporus, the "button mushroom" or "champignon de Paris" is the most widely cultivated edible species in the world. Although this species has never been reported in the wild in Greece, many specimens have been collected in different regions, during the period 1991-2001. Manure, especially...
