Abstract
The present invention relates to methods and uses of photo-labile compounds which are trehalose-6-phosphate or trehalose-6-phosphonate or agriculturally acceptable salts thereof in the induction of floral development in plants. The invention also concerns methods and the use of the compounds for the acceleration of floral development in treated compared with untreated plants.
Claims32
A method of inducing flowering in a plant, wherein the method comprises treating the plant with a compound of formula (I), a phosphonate analogue thereof, or agriculturally acceptable salts thereof:
- wherein:
- p is 0 or 1;
- R1 to R7 independently represent F, N3, NR′R″, C1-4 alkyl, —(C1-4 alkyl)OH or OH, wherein R′ and R″ independently represent hydrogen or C1-4 alkyl;
- and R8 and R9 are the same or different and represent H or a photo-labile protecting group, wherein at least one of R8 and R9 represents a photo-labile protecting group.

A method of accelerating the floral development of a plant, wherein the method comprises treating the plant with a compound of formula (I), a phosphonate analogue thereof, or agriculturally acceptable salts thereof:
- wherein:
- p is 0 or 1;
- R1 to R7 independently represent F, N3, NR′R′, C1-4 alkyl, —(C1-4 alkyl)OH or OH, wherein R′ and R″ independently represent hydrogen or C1-4 alkyl;
- and R8 and R9 are the same or different and represent H or a photo-labile protecting group, wherein at least one of R8 and R9 represents a photo-labile protecting group.

A method of co-ordinating the floral development of plants, comprising treating the growing plants with a compound as of formula (I), a phosphonate analogue thereof, or agriculturally acceptable salts thereof:
- wherein:
- p is 0 or 1;
- R1 to R7 independently represent F, N3, NR′R″, C1-4alkyl, —(C1-4alkyl)OH or OH, wherein R′ and R″ independently represent hydrogen or C1-4alkyl;
- and R8 and R9 are the same or different and represent H or a photo-labile protecting group, wherein at least one of R8 and R9 represents a photo-labile protecting group.
