Knowledge of the biology and development of vegetative organs of perennial weeds is an important step in their successful management. For this purpose, two separate experiments were conducted to investigate the effect of burial depth, duration, and storage temperature of Acroptilon repens roots on their survival and germination characteristics in the Weed Science Laboratory of the Faculty of Agriculture and Natural Resources, University of Mohaghegh Ardabili, in 2021. Factors included root length (3, 6, and 12 cm), storage temperature (-5, -10, and -20 °C), duration of storage at each temperature (7, 14, and 30 days), and burial depth (5, 10, and 20 cm). The results showed that with decreasing storage temperature, the rate of root deterioration increased significantly. Exposing the roots to low temperatures (-10 and -20 °C) in all three storage periods (7, 14, and 30 days) led to their complete destruction. The number of new plants and their dry weight were affected by root length and burial depth. With an increase in root size from 3 to 12 cm, the number of new plants increased by 3- to 5-fold, respectively. Regardless of root size, increasing burial depth reduced all studied traits by 85%. Increasing burial depth affected the survival of Acroptilon repens roots, and smaller organs had less chance to emerge at greater depths.
