Presence of Double Dormancy in Wild Persian Buttercup (Ranunculus asiaticus L.)
A. Karami and M. Khosh-Khui

Abstract:
In present experiment, the nature of dormancy in seeds of wild Persian buttercup was investigated. Scarification with 50°C hot water for 2 min enhanced seed germination. The highest Germination Percentage (GP) (98.75%) and Mean Daily Germination (MDG) (10.76%) were obtained by treating the scarified seeds with 200 mg L-1 Gibberllic Acid (GA3). These treatments resulted in seed germination, but the hypocotyls grew only to approximately 2 mm in length and then ceased the growth. Moist stratification at 5°C for 30 days significantly increased hypocotyls length. It was concluded that both mechanical and epicotyl dormancies are present in wild Persian buttercup seeds.
