The paper presents the results of investigation of variability of net
photosynthesis (A), transpiration (E), stomatal conductance (gs) and
water use efficiency (WUE) in one year old seedlings of wild cherry
(Prunus avium L.), assessed in a nursery trial. Study involved 5
families of half-sib progenies which originate from the Northern part of
Serbia (Vojvodina Province). The results showed significant differences
among families in regards of stomatal conductance (0.163-0.256 mol m(-2)
s(-1)), transpiration (3.27-5.28 mmol m(-2) s(-1)) and water use
efficiency (1.98-3.80 Firnol mmol(-1)) (p <= 3.001), while differences
regarding net photosynthesis (10.49-12.44 mu mol m-2 s(-1)) were not
statistically significant (p <= 0.124). Canonical discriminant analysis
(CDA) was performed in order to estimate multivariate relations among
analyzed leaf photosyntetical traits. Families were separated by the
first canonical axis (CD1), which described 82\% of variability.
Presence of differences in regards of E, gs and WUE indicate the
possibility of choosing the best families for a breeding program.
