摘要：Bobinac Marin,Vid Radevic (2005): Abundunce of yield in 30- year old hornbeam stund in the seed yeurs 2003 und 2004.- Acta herbologica,Vol.14,No.2,89 96,Belgrade.Hormbeam yield was analysed in the region of southwest Srem in two seed years,2003 and 2004 in a juvenile hombeam stand at the site of pedunculate oak,hormbearm and narrow -leaved ash forest.The study trees were 30 years old,with dominant biological position and with diameter 10-20 cm.During the seed year 2003,the flowering and fruit bearing branches were recorded on 76.4 % of trees;on 17.3 % of trees they were abundant,on 23.6 % of trees medium abundant,and on 35.5 % of trees individual.During the seed year 2004,the flowering and fruit bearing branches were recorded on 92.8 % of trees;on41.8 % of trees they were abundant,on 25.5 % of lrees medium abundant,and on 25.5 % of trees individual.During the seed year 2004,there was a trend of increased yield compared to 2003,expressed by a total number of trees with flowering and fruit bearing branches and by a higher number of trees with abundant flowering and fruit bearing branches.
