Abstract

Forests are the dominant land use in Albania, occupying almost 1.5 million hectares [11], but c.a. 70% of the forest area belong coppices and shrub forests, as the results of unsustainable practices, intensive cutting and overgrazing. Forest ecosystems serve many ecological roles, including regulation of the planet’s carbon and water cycles. Forests are also important components of economic systems. Research in the Forest Ecophysiology studies on the Faculty of Forestry Sciences is intended to produce biological knowledge that can be used to better manage forest resources for sustainable production of economic and non-economic values and aims to improve the understanding of past and current dynamics of Mediterranean and temperate forests. The overarching goal is to quantify the influence of genetics, climate, environmental stresses, and forest management inputs on forest productivity and carbon sequestration, and to understand the physiological mechanisms underlying these responses.Process-based models open the way to useful predictions of the future growth rate of forests and provide a means of assessing the probable effects of variations in climate and management on forest productivity. As such they have the potential to overcome the limitations of conventional forest growth and yield models. This paper discusses the basic physiological processes that determine the growth of plants, the way they are affected by environmental factors and how we can improve processes that are well-understood such as growth from leaf to stand level and productivity. The study trays to show a clear relationship between temperature and water relations and other factors affecting forest plant germination and growth that are often looked at separately. This integrated approach will provide the most comprehensive source for process-based modelling, which is valuable to ecologists, plant physiologists, forest planners and environmental scientists [10].

Actually the Albanian vegetation is presented in two different appearances:

·         on one hand the existence of the virgin forests, generally located far from dwelling centres, because the lack of the infrastructure and,

·         on the other hand the existence of degraded forests, located near dwelling centres because of intensive harvesting, abusive cutting and growing.

By the consequences the degraded ecosystems are under an ecological stress and their rehabilitation is very difficult. To develop low cost methodologies for improving vegetation which will result in functional ecosystems in far degraded Mediterranean areas by means of physiological studies is very important and a new scientific field in Albanian forestry.

The study is focused on seed germination physiology and seedling stress selection of some native evergreen and broadleaves oak species in order to determine the seed germination dependency on temperature and humidity, methods releasing germination beanies in species candidate for improving vegetation, the sensitivity of the germinating seeds and the seedlings on extreme temperatures, and the selection of drought and cold resistant seedling among populations of different geographical origin.
