Table 1 Measurements (mean ± standard deviation) of vegetative and reproductive traits at the end of A. artemisiifolia plant development. LT: Low Temperature, IT: Intermediate Temperature, HT: High Temperature. Different letters means statistical significant differences (p < 0.01) between LT, IT and HT for each plant trait
