Abstract

The first step in planning and implementing any research project is the possession of preliminary and basic data and information. Growthcharacteristics information of various POPLAR trees at seedling stage Of NURSERY, can provide many scientific and basic data for POPLAR researchers to implement different projects and apply appropriate of experimental nursenes. In this study the growth characteristics of 24 different POPLAR CLONEs (one year old seedlings) during the growth season in 1998 at Karadj Alborz Research Center, was studied. Factors such as collar diameter, height, biomass production, leaf characteristics (surface, fresh weight, dry weight, thickness, toughness and decomposition rate) for all CLONEs were measured. Over all 12 different variables were measured. Another eight variables were derived from the 12 variables. The data and information of the 20 variables were analysed, by using the PCA statistical analysis method and Minitab 8/2 software to ordinate the POPLAR CLONEs with similar function. The 20 measured variables were ordinated again to identify variables which have effective role in POPLAR CLONE grouping. Based on the 20 measured variables, the results showed that, the CLONEs of Populus x euramericana had the highest similarity, whereas the CLONEs of Populus deltoides were divided to two groups and the CLONEs of P.alba and P.nigra did not have significant difference. Among the 20 variables which were studied in the NURSERY, only 9 variables influenced the CLONE grouping. Therefore by applying less numbers of variables which they are comfortable to use, we will be able to classify similar CLONEs. Although there were enough soil moisture, appropriate air temperature and green and fresh performance of the CLONEs, the diameter and height growth of some CLONEs such as P.deltoides72/51and P.candicans terminated or decreased significantly at late August whereas some of CLONEs such as P.e.triplo, P.d. 69/55, P.d.77/51, P.d.73/51 and P.n.betulifolia continued growing until late October. This was one of the reasons of the highest growth of these CLONEs amongst the other CLONEs in the NURSERY.
