Definitions
- the present invention relates to the new use of a known compound, to novel agricultural compositions containing that compound, to methods of preparing the compositions and to methods of their use, in particular in the treatment of plants.
- caffeine is well known and has many uses. It is a purine alkaloid. Purine is 7H-Imidazo [4, 5- d] pyrimidine and the caffeine family are optionally alkyl substituted dione derivatives thereof.
- caffeine is known to be of use as a fungicide. It is also known to have an effect on the rate of DNA repair in plants. Also, in one study (Biologia Plantarum, (1998) vol. 40, No.3, pp 329-335), caffeine was shown to be able to produce a weak cytokinin-like effect on cotyledon growth, chlorophyll biosynthesis and cell elongation in the systems studied.
- caffeine can have non-cytokinin effects on plant growth and that caffeine and other related members of the purine alkaloid family have a use as plant growth stimulators.

Further in fruiting plants an earlier increase in the sugar content of the fruit is observed as well as higher fruit sugar levels achieved. Also plant colouration can be enhanced, particularly where carotinoids are present, such that there is an enhancement in and acceleration of colouration, in particular with red, yellow and orange pigmentations.
