wateruse efficiency (WUE) (Hirose and Bazzaz,
1998). Higher draught adaptability, in other words
reducing the negative effects of the lack of water, the
invasive species are accomplishing through high rate of
photosynthesis per unit water loss (high WUE).
Generally, photosynthetic capacity, growth rate
resource acquisition, allocation, and phenotypic plas
ticity are higher in invasive and introduced, than in
native species (Nilsen et al., 1993; Pattison et al.,
1998). According to Brodersen et al. (2008) enhanced
photosynthetic rates do not indicate successful inva
sive genotypes. Morphological traits and defensive
secondary compound metabolism instead may play a
more important role in the success. Likewise, by inves

—Environmental factors like temperature and soil humidity are recognized as influencing factors on
photosynthetic response and organic productivity, distribution and biochemical characteristics of plants.
Here we present measurements of gas exchange parameters, wateruse efficiency (WUE) and nitrogenuse
efficiency (NUE) of fieldgrown invasive species
Nutt., in order to define their potentials as colonizers. Biogenic volatile organic compounds
(BVOC) in leaves and flowers depending on soil humidity were also investigated.
Results indicated species
as the colonizer with the highest physiological potential because of
its high WUE in its vegetative phase and also the highest NUE and the highest photosynthesis/dark respira
tion ratio in its flowering phenological phase. It was found that the volatile compounds of
consist mainly of terpenic compounds. There was a significant difference among the spe

tative ratio of monoterpens in flowers and leaves of
