اثر گلیفوسیت بر روی جوانه‌زنی غده اویارسلام ارغوانی (Cyperus rotundus)

In order to determine the dose-response assessment of germination and growth of purple nutsedge tubers compared to the Glyphosate herbicide. A factorial experiment carried out with three replications at Birjand University Research Laboratory was conducted. Treatments experimental consisting The first factor, different populations including Birjand, Kahnooj and Jiroft and second factor included concentrations ten including control, 0/00034 M, 0/00068 M, 0.0017 M, 0.0034 M, 0.0068 M, 0.107 M, 0.034 M, 0.068 M, 0.17 M and 0.34 M Glyphosate rate with 10 mL water was applied. The results showed that with increasing concentrations viability examined viability tuber and tubers germination in all three tuber populations significantly was decreased. Whereas the tubers viability of these populations show high resistance to tuber concentration than 0.034 M, populations Kahnooj and Jiroft and the concentration of 0.068 M, population Birjand was observed.
