Abstract

This experiment was carried out in order to study the effects of SALINITY stress on germination components of 3 different CHAMOMILE (Matricaria chamomilla) ecotypes. The effect of the 6 levels (0, 2, 4, 6, 8 and 10 ds/m) of salt (NaCl) stress on 3 CHAMOMILE ecotypes (Gorgan, Semnan and German) was studied as a factorial design in the basis of completely randomized design with 4 replications. The measured and calculated traits were the percentage and rate of germination, the length of radical and plumule, dry weight of radicles and plumules, vigor index and salt tolerance index. The effect of salt stress was significant on all traits. By increasing the SALINITY a significant decrease was observed in the traits and most of the traits showed significant decrease in their values compared to the control group, even at the lower levels of SALINITY stress, indicating the high sensitivity of CHAMOMILE seeds to salt stress. The percentage and rate of germination were, respectively, 74.67 percent and 4.64 in control group, and these values decreased significantly to respectively, 65 percent and 3.7 at the lowest level of SALINITY stress, which showed further decrement by increasing the SALINITY stress. The effect of ecotype was also significant on all traits except the length of plumule and SALINITY tolerance index. The percentage and rate of germination, the dry weight of plumule and radicle and seed vigor, with respective values of 75.83%, 4.12, 0.617 mg, 2.088 mg and 10.91, were significantly higher in Semnan ecotype compared to the other ecotypes. The percentage and rate of germination and seeds vigor were significantly lower in Gorgan ecotype compared to the other ecotypes.
