Abstract:Pri 10 zdravih jelkah (Abies alba) smo raziskali anatomsko zgradbo floemskih branik (FB) glede na njihovo širino, razmerje med številom slojev celic v FB in v ksilemskih branikah (KB) iste sezone, razlike v številu slojev celic v FBin KB po obodu posameznega drevesa ter zvezo med širino FB in KB, nastalih vistem letu, ter širino dormantne kambijeve cone (KC). Intaktne vzorce tkiv zaraziskave smo vzeli iz živih dreves v letih 2001 in 2002 ter pripravili preparate prečnih prerezov za svetlobno mikroskopijo. Ugotovili smo zvezo med širino in anatomsko zgradbo FB. Pri ožjih FB je prevladoval rani floem, pri širših pa kasni. Pri širših FB se je v kasnem floemu lahko pojavil dodatni pasaksialnega parenhima. KB so bile 2- do 21-krat širše od FB. Širina KB je poobodu posameznega drevesa bolj variirala kot širina FB. Širina dormantne KC je bila v pozitivni zvezi s širino FB in KB.

Title:Relation between xylem and phloem increment in Silver fir (Abies alba Mill.)
Abstract:In 10 silver firs (Abies alba), the following was investigated: anatomical structure of phloem growth rings (FB) in relation to their width, ratio between number of cell-layers in FB and in xylem growth rings (KB), variation in number of cell layers in FB and KB around the stem circumference, relation between widths of FB and KB formed in the same year, and the width of dormant cambial zone (KC). Samples of intact tissues were taken from living trees in 2001 and 2002, and permanent cross-sections for light microscopy prepared. We observed the relationship between width and anatomical structure of the FB. Narrower FB contained more early phloem, whereas wider FB contained more late phloem cells. Wider FB sometimes contained an additional band of axial parenchyma. The KB were 2 to 21 times wider than the FB. The widths of KB varied around the stem circumference more than the widths of FB. The widths ofdormant KC were positively correlated to the widths of FB and KB.
