Abstract
THE present communication summarizes the results of eight hours prechilling soaking treatment at room temperature with different concentrations (500, 50, 5, 0.5, 0.05 and 0.005 parts per million in distilled water) of α-naphthaleneacetic acid, indolylbutyric acid and indolylacetic acid on the process of vernalization in Linum usitatissimum Linn., strain 477–3/2. Soaked seeds from each treatment were spread over cloth moistened with a solution of the same strength or with water and kept in Petri dishes inside a refrigerator, maintained at a temperature of 4–8° C. Mucilage on the seed-coat retained the solutions during the entire period of chilling (24 days), and this ensured a continuous supply of hormones to the embryo.
