Abstract

In order to investigate the germination variables of different barley lines and cultivars, an experiment was conducted at Agricultural Research Station of Islamic Azad University, Ardabil Branch, using completely randomized block design with three replications. In this study traits such as root length, shoot length, mean germination rate, mean germination time, root dry weight, seedling vigor, chlorophyll content index and Vigor index were evaluated. Randomized trials were used. Factor analysis was performed on the traits measured by principal component method. Factor analysis showed that the first factor accounted for the largest amount of data variations, with seedling length traits on the first day of transfer to pot, seedling length on the fourth, eighth, twelfth and sixteenth days after transfer having a large positive coefficient. This factor can be introduced as a seedling growth factor.
