Evaluation of forage sorghum [Sorghum bicolor (L.) Moench] lines for drought tolerance at germination stage
Abstract
Drought is a major factor which limits growth and development of higher plants. This study was conducted to evaluate the effect of drought on the germination and early growth of forage sorghum lines. In order to an experiment was performed as factorial form under completely randomized design (CRD) with 3 replications. Line factor contained 15 lines and 5 levels of drought (control, -3, -6, -9 and -12 bar) with PEG 6000. Results showed that the most negative and significant correlation had between germination rate and mean germination time (r=-0.98**) and the most positive and significant correlation had between root length and seedling length (r=0.99**). Factor analysis based on principal component analysis showed that three independent factors, respectively, 52, 21 and 10% of all variation data determined. In the first component germination percentage, germination rate, root length, seedling length, index seed vigour and dry weight of seedling positive factor coefficients were shown. In the second component mean germination time, root/shoot length ratio and dry/wet weight ratio negative factor coefficients and shoot length positive factor coefficient were shown. In the three component reduced germination negative factor coefficient was shown. Based biplot, lines of KFS2, KFS3, KFS6, KFS7, KFS8, KFS9, KFS10, KFS11 and KFS12 were low sensitive to drought stress and lines KFS1, KFS13, KFS15, KFS16, KFS17 and KFS18 were high sensitive to drought stress.
