Study of germination traits of 20 genotypes of monogerm and polygerm sugar beet through analysis at osmotic situation

摘要

Research was done according to germination indicators and experimental growth as factorial in form of random block plan In order to categorize genotypes of monogerm and polygerm of sugar beet at laboratory. 14 traits were evaluated. Three factors with high amounts were selected among others which have encompassed 83.17 percent of initial data variance. Results showed that sharing coefficient of most traits were high, so number of selected factors was appropriate and selected factors could justify traits changes desirable. First factor have been justified about 40.69 percent of initial variables, so that FGP, CVG, GRI, MDG, RS and MTG had positive and negative coefficient. So this factor was introduced as germination indicators. Second factor have been justified 26.91 percent of changes. Cotyledon length, root length, seedling fresh weight, seedling dry weight, root dry weight and total dry weight influenced on this factor, so it was called growing indicator. Finally, third factor have been justified 15.51 percent of changes. Root fresh weight and total fresh weight influenced on this factor. Totally, these three factors have evaluated a specific trait against others
