The study of the influence of temperature on the flowering process of citrus is based on a long term series (10--17 years) at 7 locations in Israel, as well as 4 years of intensive observations on 20 citrus trees.
Results obtained indicate that the commencement of flowering depends on the temperature climate of the previous winter season. Frosty winters delay the date of the commencement of flowering by some 15 days. During 'normal' winter seasons, the colder the winter season the later the flowering period will commence.
The duration of the flowering period is also temperature dependent. It has been shown that some 86 day-degrees are required to complete the flowering phase. However, the number of day-degrees will vary slightly depending on the temperature. The lower the temperatures, the larger the day-degree requirements.
It is suggested that temperature data can be used to predict the commencement and duration of the flowering period of citrus.

## Abstract Many plants flower in response to a change in the environment. Since one of the main goals for a plant is to complete a growth cycle in order to produce seed, flowering is a key stage in plant development. We have developed a statistical procedure for explaining the variations in flower
