The Principal Characteristics of the Trees Studied in a Comparative Culture of Beech in the Apuseni Mountains, Romania
Abstract
The biological material represented of 31 provenances of beech (Fagus sylvatica L.) has been analyzed in a comparative culture of descendents in Aleşd, Poiana Florilor, Bihor, Romania. The study material was representative for 17 European countries, from almost the entire natural area of the specie, including Romania. The seedling plants used in the setting up of the culture were two years old and came from the nursery of the Institute of Forest Genetics Schalembeck, Germany. The culture’s area of settlement was in the G2 zone, the Apuseni Mountains (Pădurea Craiului Mountains), subzone G240-hilly beech woods, while the experimental appliance for the culture was a 3x4 rectangular railing, with three repetitions, completely randomized, each unitary lot covering 10x10 m, and being made up of 50 plants placed on five rows with a 2 meter distancing in between and 1 meter distance within the row. The study was performed 5 years after planting, and following peculiarities were analysed: percent of survival of the trees (%), total height of the trees (cm), base diameter (cm) and forking (indices).
