Greenhouse study was conducted in 2013-2014, in order to investigation of freezing effect on roots developing reproduction capability in two Cynanchum acutum L. populations. The freezing temperature of two C. acutum populations (Karaj and Kerman) determined at -1, -2, -4 and -8° C; for durations of 0 (Evidence), 6, 12, 24, 48 and 96 hours. Results showed that the increasing of the duration and decreasing the freezing temperatures, the number stalk and leaves obtained from each root were declined. But Karaj population showed rather resistance to freezing. The results of study showed that, freezing can be used as appropriate management solution with the aim of weed control and management. Freezing efficiency was effective for weed management of Karaj and Kerman population.
