Description
  • V příspěvku je řešena problematika korun a asimilačního aparátu douglasky tisolisté. Analyzovány byla koruny dvou stromů ve věku kolem 70-ti let odlišného cenotického (nadúrovňový - podúrovňový) a produkčního (objemové min. -- max.) postavení v porostu. Jedinci poházeli z experimentálního porostu 41D7 na ŠLP %22Masarykův les%22 Křtiny (430 m n.m.). Rozdíly mezi vzorníkem č.1 (podúrovňový strom, V=0,44 m3) a vzorníkem č.2 (nadúrovňový strom, V=2,37 m3) byly zjištěny již při analýze výškového a tloušťkového přírůstu. Vzorník č.1 se vyznačoval nejen kratší korunou, a to jak absolutně tak relativně (v % délky kmene), ale taky kratšími přeslenovými větvemi a jejich nižším počtem. Zatímco koruna vzorníku č.1 byla tvořena 28 přesleny s 3,5 větvemi na přeslen, u vzorníku č.2 to bylo 37 přeslenů a 4,5 větví. Odlišný průběh byl zjištěn také v případě distribuce jehlic (g.m--1). Pro nadúrovňový strom byla typická jednovrcholová křivka, naproti tomu strom podúrovňový se vyznačoval nepravidelným vícevrcholovým rozmí (cs)
  • The paper deals with problems of crowns and of the assimilatory apparatus of Douglas fir. Crowns of two trees aged about 70 years of different coenotic (dominant - subdominant) and production (volume: minimum- maximum) position in a stand were analysed. The trees came from the experimental stand 41D7, Training Forest Enterprise %22Masaryk Forest%22 Křtiny (altitude 430 m). Differences between Sample tree 1 (subdominant tree - V = 0.44 m3) and Sample tree 2 (dominant tree,V=2.37 m3) were found in the course of the analysis of height and diameter increment. Sample tree 1 was characterized not only by a shorter crown, both absolutely and relatively (in % of the stem length) but also shorter whorl branches and their lower number. While the crown of Sample tree 1 was created by 28 whorls with 3.5 branches/whorl, Sample tree 2 was created by 37 whorls and 4.5 branches/whorl. A different course was also found in case of needle distribution (g.m--1). A unimodal curve was typical of the dominant tree while the su
