Abstract
Described are compositions and methods to mitigate alternate bearing of perennial crops by use of a natural metabolite. In particular, the present disclosure provides a natural metabolite in the presence or absence of an auxin transport inhibitor to increase floral intensity (flower number) of the return bloom in the spring following the setting of a heavy on-crop to increase the yield of the putative off-crop year and, thus, increase cumulative crop yield. Additionally the present disclosure provides a natural metabolite in combination with one or both of a growth promoting type of plant growth regulator, and a hormone biosynthesis, transport or function inhibiting type of plant growth regulator.
Claims12
A composition effective in mitigating alternate bearing in a perennial crop plant, comprising:
- (i) a purified adenosine comprising 9-beta-D-adenosine, (ii) and an auxin transport inhibitor, wherein the auxin transport inhibitor is
- 2,3,5-triiodobenzoic acid;
- or
- a flavonoid or isoflavanoid selected from the group consisting of naringenin, quercetin, formononetin, and genistein;
- and,
- wherein, the 9-beta-D-adenosine and the auxin transport inhibitor are more effective in mitigating alternate bearing when applied to the perennial crop plant in combination than 9-beta-D-adenosine alone.
