Abstract
The influence of temperature on breaking the rest period was studied.
Most foliage leaves develop after a rest period of 80–120 days at 10–15° C. At 25° C the development of foliage leaves was totally prevented.
Rest periods at 5° C and below caused the death of the plants.
The rest period must be given after the end of the vegetation period.
Under unfavourable conditions the plants differentiated fewer leaf primordia.
Most foliage leaves develop after a rest period of 80–120 days at 10–15° C. At 25° C the development of foliage leaves was totally prevented.
Rest periods at 5° C and below caused the death of the plants.
The rest period must be given after the end of the vegetation period.
Under unfavourable conditions the plants differentiated fewer leaf primordia.
The temperature during the rest period determines how many of the primordia develop into foliage leaves.
Correlation exists between number of foliage–leaves and flower initiation.
Increase in foliage leaves favours flower production.
