Effect of treating the seeds and seedlings with chilling and diethyl sulphate on the growth and flowering of Antirrhinum majus [electronic resource].

Includes reference.

Seeds and seedlings of Antirrhinum majus cv. Snowflake were chilled (4 and -20"Cfor seeds and 4"Cfor seedlings) or treated with different concentrations o/the chemical mutagen diethyl sulphate (DES) (0.3, 0.6 and 0.9%) and then the treatments were transplanted In the plastic house and on the open field. The effect on the vegetative growth, flowering characters and induction of variations was assessed in three generations. In general, the decrease in plant height and inflorescence length was correlated with increasing the concentrations of DES and decreasing the temperature or the period of exposure to chilling. The variations included dwarf plant and leaf and floret changes.
