Preliminary experiments on vernalisation

  • G. D. H. Bell (a1)
Extract

1. Low temperature grain pre-treatment of some varieties of wheat, barley, and oats, has resulted, in most cases, in a stimulation to early development of the plant with a modification of the juvenile habit.

2. In addition to early developmental stimulation, winter varieties of barley and wheat also showed marked acceleration in the date of earing. Spring varieties either failed to show this earing acceleration or else were but slightly affected.

3. Glasshouse culture during the first few months of growth resulted, in most varieties, in a greater response to the grain pre-treatment. It is suggested that this was due to the absence of low temperatures in the glasshouse.
