CORRELATIONS ANALYSIS BETWEEN SOME MORPHOLOGICAL CHARACTERS ON ENERGY WILLOW GENOTYPES

O. PANITA

Abstract


In three different areas, Radovan, Ișalnița and Tâmburești, there were tested 14 Romanian and Swedish genotypes of energy willow, the analyzed characters being stem diameter on the base, total grow/pl., grow/stem, plant height and. no. of stems/pl. Based on average values recorded for this characters, there were calculated the correlations between those ones, for every area. Stem diameter on the base character is positive correlated with grow/stem character in Radovan and Tâmburești areas, and with total grow/pl. in the Ișalnița area. Trend models based on linear equation were calculated between grow/stem and stem diameter on the base in the Radovan area and between stem diameter on the base and total grow/pl. in the Ișalnița area. Plant height and no. of stems/pl. characters are in no correlation character regardless of location or character.
