Analyses of height and diameter growth on the basis of 191 sycamore trees from 30 different locations were carried out. Additionally, the height increments of sycamore's seedling from three locations were measured every ten days during the growing period. The results show that on maple sites the sycamore grows faster in height than the sycamoreon beech and silver fir-beech sites. Concerning the diameter growth, the sycamore on maple sites has a higher rate of growth in the early years, but is later on overtaken by sycamore from beech as well as silver fir-beech sites. The largeness of sycamore's crown influences the tree ring width. The current annual increment of height most often culminates between 12th and 14thyears of age, while diameter CAI culminates between 20th and 40th years ofage. The mean annual increment of height reaches the peak mostly between 20th and 25th years of age, while diameter MAI reaches it mostly between 30th and 50th years of age. The height increment of sycamore has a single distinct culmination in the growing period, with intensive growth of height lasting for30 to 40 daysPrispevek obravnava rastne značilnosti gorskega javorja na štirih skupinskih gozdnih rastiščih v Sloveniji. Analizirali smo višinsko in debelinsko rast 191gorskih javorjev s 30 lokacij. Na treh izmed njih smo opravljali desetdnevne meritve višinskega priraščanja mladic gorskega javorja. Pokazalo se je, da gorski javor v višino najhitreje raste na javorovjih, sledijo bukovja in nazadnje jelovo bukova rastišča. Kar zadeva debelinsko rast, v mladosti najhitreje rastejo javorovja, kasneje pa jih prehiti gorski javor z bukovih in jelovo bukovih rastišč. Debelinsko priraščanje je v pozitivni povezavi z velikostjo krošnje. Tekoči višinski prirastek najpogosteje kulminira med 12. in 14. letom starosti, debelinski pa med 20. in 40. letom. Povprečni starostni višinski prirastek doseže kulminacijo večinoma med 20. in 25. letom, povprečni debelinski prirastek pa med 30. in 50. letom starosti. Višinsko priraščanje gorskega javorja ima eno in izrazito kulminacijo v rastnisezoni, čas intenzivnega priraščanja pa traja 30-40 dniTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Biotehniška fakulteta
