Determination of the Stomatal Index of Betulae folium
STANOVENÍ STOMATÁLNÍHO INDEXUBETULAE BETULAE FOLIUM
U listů břízy pocházející z Betula pendula ROTH a B. pubescens EHRH. a sbíraných během vegetacev různých lokalitách byl zjišťován stomatální index (S.I.). Jeho hodnota je v rozmezí 3,30 ± 1,31 –7,33 ± 3,13 u B. pendula ROTH a 3,66 ± 1,34 – 12,06 ± 3,26 u druhu B. pubescens EHRH. S větší čimenší významností je hodnota S.I. závislá na stáří listu, matečné rostlině a lokalitě.
