Asclepias syriaca is a perennial species, native to North America. In Romania, being introduced as an ornamental species, in present being found in different habitats (agroecosystems) and on ever wider areas causing damage. Although the basic biological characteristics of Asclepias syriaca are known, its control is a significant problem. As a result, we hypothesized that temperature and sowing depth can be used to reduce the population of Asclepias syriaca. To test this, the seeds were put at 5?C, 27?C, room tempe...
