SUMMARY .Genotype differences have been investigated in six poplar
clones (Populus nigra, Populus x euroamericana 1-214, Populus deltoides
618, Populus deltoides 457, Populus balsamifera, and Populus deltoides ssp.
angulata) in nursery conditions, as to the number and size of the stomata,
and the concentration and accumulation of nutrients in the leaves. Analyses
have been made for the following nutritious elements: N, P, K, Ca, Mg, S,
Fe, Mn, and Zn.

Among the mentioned clones, genotype differences have been established
as to the number and size of the stomata, and the concentrations and accumulation
of nutrients in the leaves.

The clones of the Populus deltoides 618 and Populus deltoides 457 generally
have very high concentrations of nutrients in their leaves, while, owing
to particularly large leaves, Populus deltoides 618 gathers the greatest amounts
of the already analyzed nurients in a certain number of leaves. Populus
deltoides 456 is characterized by particularly high concentrations of sulphur
in its leaves. The greatest number of the stomata, both on the face and back
of the leaf, is found in the clone Populus deltoides ssp. angulata. We found
also statistical differences in respect to size of the stomata on the face and
leaf back. The greatest length of the stomata have 1-214 and P. balsamifera
clones.


The obtained results show that there are remarkable differences as to the
physiological features among the clones which have been reproduced in Croatian
nurseries and grown in forest cultures. It is of great importance for
successful vegetative progeny production and raising of poplar cultures and
plantations, that the poplar clones are chosen in accordance to the given
habitat, respecting their physiological status. In the future it is neccessary to
investigate also the nutrient content of total biomass in nursary condition.
Nutrient accumulation in weed vegetation is also important because weed
vegetacion is in competition to poplars in nursaries and plantations.
