Abstract: Leaf gas exchange was investigated on six linden cultivars from Tilia cordata Mill., T. platyphyllos Scop., T. tomentosa Moench
and T. americana L. After the morning peak rapid stomatal closure was detected on leaves of T. cordata 'Savaria', 'Greenspire'
and T. platyphyllos 'Favorit'. The stomatal conductance on leaves of T. tomentosa 'Szeleste' after the midday drop was significant
higher, while highest was on T. americana 'Redmond' leaves during the whole day. According to the effect of leaf surface
temperature on stomatal conductance three groups of the examined linden cultivars were appointed. Corresponding
to their drought and heat adaptability the performance of leaves of T. tomentosa cultivars showed intermediate level of
transpiration. The large cultivar differences in the performance of leaf gas exchange should be considered at evaluation of
drought stress adaptability and environmental benefits (CO2 fixation, O2 and vapor release) of Tilia cultivars.
