ﻣﻄﺎﻟﻌﻪ زادآوری ﺑﺬر ﺣﺎﺻﻞ از ﻋﻠﻒﻫﺮز ﭼﺎودار وﺣﺸﻲ (Secale cereale) در ﺗﺪاﺧﻞ ﺑﺎ ارﻗﺎم ﮔﻨﺪم

This research was carried out as factorial based on a completely randomized design with three replications at seed physiology laboratory, ferdowsi university of mashhad. Feral rye seeds (Secale cereal) were harvested from four densities of 20, 40, 60 and 80 plants per area in interference with wheat cultivars of Sayson, Alvand, Chamran and Sepahan. 25 feral rye seeds from each of interference plots of field were separated and were considered as an experimental unit. Results showed that by increasing mixed canopy density reduced germination ability of seed from feral rye. Also, feral rye seeds obtained of interference with Alvand and Sepahan cv. had lower percentage and rate of cumulative germination than other two cultivars. Sepahan cv. in compared to other wheat cultivars had highest negative effects on feral rye from the viewpoint of seed number with ability of germination. Thus, aforesaid cultivar was appropriate for control of field pollution, in both the short and long time.
