Chemical spray keeps cut peony flowers fresh days longer

Postharvest Science

That bouquet of peonies wilting on your kitchen table in two days instead of a week might soon last longer thanks to a simple post-harvest treatment florists could adopt.

Cut peony flowers droop and fade fast once removed from the plant, which is a big problem for growers and flower shops. Researchers tested a compound called fluridone on two peony varieties and tracked the plant chemistry and genes involved in aging, finding it slows down the wilting process. This kind of work could lead to longer-lasting cut flowers on store shelves and in home vases.

Key Findings

1

Fluridone treatment delayed visible senescence symptoms in cut flowers of both 'Luoyanghong' and 'Xueying Taohua' tree peony cultivars

2

The treatment altered biochemical markers associated with flower aging, such as antioxidant activity and membrane stability

3

Gene expression analysis identified specific senescence-related genes whose activity shifted in response to fluridone treatment

Treating cut tree peony flowers with a chemical called fluridone helps them stay fresh longer after cutting, giving florists and flower lovers more time to enjoy the blooms before they wilt.
