The effect of chemical scarification and washing on the germination of Ferula ovina seeds

摘要：

Germination is a critical stage in the life cycle of weeds and crop plants, and often controls population dynamics, with major practical implications.Washing ( with cold water) has been one of methods the traditionally used to break seed dormancy (Frisby and Seeley, 1993 ; Nadjafi et al, 2006 ).The chemicals which are used commercially in various places include : potassium nitrate, thiourea, sulfuric acid, ethanol and Cyanamid.All of these chemicals are inexpensive and can be used easily to break the true dormancy of seeds effectively (Chang and Sung, 2000).
