The work deals with the above-ground dendromass formation and its relationship to both leaf area index (LAI) and climatic conditions in different stand types of European chestnut (Castanea sativa Mill.) at the series of PRP Lefantovce (Forest administration Nitrianska Streda, Forest enterprise Topoľčianky, Slovak Republic) tended during 25 years by moderate crown thinning with frequency of 5 years. The highest mean periodical increment per leaf area unit (g square dm per year) was observed in all stand types during years 1977-1981 and 1982-1986. It was found out that production of above-ground dendromass of European chestnut stands is in close correlation with LAI, with admixture of woody-plant species in stands, their tending (thinning) and climatic conditions. Rainfalls showed to be the limiting factor (not less than 500 mm per year).
