Abstract:

Details are on the intensity of transpiration, calculations for a particular type of forest vegetation consisting seedlings Pinus silvestris (pine) Eleagnus angustifolia, Acer pseudoplatanus (sycamore), Picea abies (spruce) and Robinia pseudacacia (acacia), planted at the age of two to three years. Studied species can generally be used for the restoration of degraded land and transpiration intensity directly correlates of seedlings water consumption. It is thus a direct indicator of water requirement for development of seedlings in good condition. Robinia pseudacacia’ seedlings realized transpiration averages significantly higher intensity than the other species. Also, seedlings of Pinus sylvestris showed water loss through sweating significantly higher than Eleagnus angustifolia seedlings, Acer pseudoplatanus and Picea abies. The lowest values were recorded by Picea abies seedlings. The seedlings were monitored during the years 2009 - 2012, the vegetation being installed on some dumps, resulting from old mine sites in the region Anina - Romania. Observations were made on ten research units at different levels of altitude ranging between 490 m - 740 m average slope is 20 units studied, presenting an exhibition targeting southern and south-east. The local climate is temperate continental, with average temperatures ranging between -17°C in winter and 4.8°C in summer between 12°C and 18°C. Average annual rainfall in the study area ranges around 70 mm. The vegetation period (average daily temperature usually exceeds 18°C) begin perimeter area studied in early May and ends in the second decade of October. Average temperatures during this period are summarized approximately between 12 and 15°C. As a type of soil are found cambisoi
