Effect of saline water on quantitative and qualitative traits of Dill (Aniethum graveolens L.) seeds

Saline stress is major human problems that thousands of years since. So that saline stress can reduce ability crops produce on land count. Saline soils in arid and semi-arid regions of Iran and developed a level equivalent to 15 million hectares of country covers. To evaluate the effect of different levels of saline water on germination and seedling vigour of Dill, this experiment was performed by completely randomized design with four replications in 2009 at the Faculty of Agriculture Laboratory Islamic Azad University, Shahr-e-Qods Branch. In this experiment the effect of five saline water levels to 0, 2, 4, 6, 8, 10 dS on germination and seedling vigour was evaluated. Statistical results showed that the effects of salinity was significant on seedling vigour, germination, seedling dry weight, germination rate coefficient, mean daily germination, germination rate and daily mean time. In general, increased salinity decreased the germination percentage. Maximum germination percentage to 79 percent control with the lowest salinity level of about 10 dS m 3 / 18 percent and increasing its salinity and proportional seedling decreased stamina. Considering the components of seedling germination and stamina can be concluded that plants get from germination to salinity levels of irrigation water that it more than 4 dS m is sensitive.
