The evaluation of drought resistance with subordinate function showed that：There were no significant differences among drought resistances of varieties and provenances. The change of physiological indices in different varieties showed differ-ent ranges. The drought resistance of seven varieties decreased in order as fol ows：Koroneiki〉 Picual〉 Berat〉 Kaliniot〉 Frantoio〉 Coratina〉 Arbequina.展开更多

The surveys are based on objective financial and expenditure data as well as on subjective views about housing conditions. The objective approach showed that mountainous areas of Greece are burdened with much higher energy expenditure while also having lower annual incomes. Under these circumstances, the energy poverty rate skyrocketed to73.5%. The subjective indicators reveal significant aspects of the problem, such as the intense problem of damp walls and mold growth at home or the restriction of other basic needs in order to cover heating needs. However, despite the proven high vulnerability of Greek mountainous areas, current energy policy actually ignores the special features of mountainous areas, implementing horizontal policies.Therefore, a specialized energy plan targeted to alleviating energy poverty in mountainous areas in Greece is an urgent imperative.展开更多

The set of compared heat energy sources comprised nine different sources. After normalisation （which meant recalculating the impacts into their proportions to the average impact of the kind, experienced by an average European in a year）, weighting （which meant attaching arbitrary weights to three aggregate impact categories according to a methodology Eco-indicator 99 E/E） and summation of the weighted results expressed in so-called ecopoints, the coal combustion furnace turned out to have the greatest impact. It was followed by an electric stove and an oil burning furnace. The wood burning furnace and the heat pump had the smallest impact, almost equal in size.
